## Suggestions from the Field

#### People are sharing such lovely ideas about how families can be doing interesting, engaging math at home. Here are some examples, with commentary about ways to extend or alter them for children of different ages.

**May 22, 2020**

**Representing Counting by Groups of 2** How could you show counting by 2s with things at home?

Hi F2! Today we have made a counting caterpillar, using plates and socks, to help practise counting in 2’s. Can you practise counting in 2’s? Here is a link to a counting in 2’s song to help you….https://t.co/e4Vm0HNIfQ#CPSPelican #CPSPhoebe pic.twitter.com/Ytiutc9UWR

**Describing a Cube** Can you find examples of a cube at home? How would you describe them? How many faces? How many vertices?

After doing a Shape Scavenger Hunt to practice the properties of 3D and 2D shapes, E describes the properties of a cube. There are so many benefits in hands-on learning! #trinitylearns #MBtos #virtuallearning #distancelearning pic.twitter.com/cfLiQNEEix

**Roller Derby** Practice sums, and think about strategy (probability)! Directions here.

L went for the fancy buttons in our Roller Derby rematch! It’s such a good game with lots to notice & conjecture about. As we tallied our sums, she decided we should use the buttons we pulled off the board if we could, which let us see our actual roles & initial placement. #tmwyk pic.twitter.com/II6gfOxBTD

**A Number Hunt** What numbers can you find? Can you find decimal numbers? What do the numbers tell you?

#homesteadmath #hrcemath

What's the context behind numbers. The digit 2 in one setting can be very different in another.

**Race to Fill. **Roll, add, and put a [grape] in the answer. For older kids: roll, add, and multiply by 7. Race to fill all the sections.

Another simple activity to set up and easy to differentiate (YR and Y3 here). We turned it into a race to fill all the sections and they loved it! 😊#homeschooling #homelearning #MathsEveryoneCanAtHome #math pic.twitter.com/9mYFskVrby

— Maths 4 Kids (@Maths4Kids) April 18, 2020

**How many windows?** Young children can think about 1 or a few floors and how they know. Older children can think about more floors, and whether they can figure out the number of windows on [10 or 20] floors without first figuring out 1-9 or 1-19 floors.

If all the sides of this building are identical, how many windows are there on 1 floor? 2 floors? 20 floors? #grid #ParentsCount #STEAM pic.twitter.com/mfL9PpztTM

— Bedtime Math (@BedtimeMath) April 21, 2020

**Fractions of Squares** Do you see 1/4 in the image? Can you see 1/4 another way? How would that change if the teal and yellow sections together equal 1? Additional images and challenges: image 2, image 3, image 4, image 5. (Inspired by Traci Jackson’s Math Walks and Nat Banting’s Fraction Talks.)

What do you notice? How many ways do you see 1/4? What if 1=teal+yellow? What fraction is gray? What other questions could you ask? #mathwalk @takemathoutside @FractionTalks pic.twitter.com/8W7aYSEvvo

— Trish Kepler (@KeplerTrish) April 25, 2020

**Comparing Nonstandard Units **Find different objects you can use to measure length. Compare how many of each it takes to measure the same length. Which results in the largest measurement? the shortest? Why do you think that is?

#Nonstandard units of #measure that may be found @ home. Which unit would you choose to measure the length of…

✅ a table?

✅ a foot?

✅ a door?Why did you choose that unit? What other units can you think of?#HRCEmath @HRCE_Math @OSullivanSonya @DeniseGB55 @ya_wolfe pic.twitter.com/bib2RwQEV1

**What fraction is [gray]?** Can you figure out what fraction of the square is each color? What color/colors would make up half of the shape? a fourth?

Today the Gr 5 students are looking at this; so far they're doing really well, finding all sorts of ways of making their fractions. Good for my mental addition! pic.twitter.com/YSXlM4IZ7J

**Strike It Out **In this game, Player 1 chooses two numbers to cross out on the numberline and then finds and circles the sum or difference of those two numbers. Player 2 crosses out that circled number, chooses another to cross out, and circles the sum or difference. The winner? The player who prevents their opponent from being able to take a turn. (Directions, from @nrichmaths.)

Maths at home! Back to @nrichmaths for another problem-solving based game (involving addition and subtraction within 20), including video instructions. Lots of mathematical reasoning about what is and isn't possible is likely. See: https://t.co/Ont82cN8Ra #homeschooling pic.twitter.com/XN9pgGMU6D

— Marilyn Burns (@mburnsmath) April 22, 2020

**Collecting Data **Decide on something to collect data about at home or in your neighborhood. Discuss how to collect the data and then collect it. Discuss what it tells you and any new questions it raises. You might want to refine your method (e.g., I think we should only count people once). Once you are happy with your method, collect data for a few days, and compare the data. Is it similar or different? Why do you think so?

Collecting data in our neighborhood. We thought about some important questions:

-If we saw the same person twice, do we count them once or twice?

-What should we do if they have a mask but it’s not on?

-Why are some people wearing masks and others not? pic.twitter.com/aOlZQgWOT7— Kassia Wedekind (@kassiaowedekind) April 21, 2020

**1,000 Bullseye **This game – from Box Cars and One-Eyed Jacks – involves addition, multiplication, and strategy!

#dailySTEM #burnabylearns math game 1000 Bullseye…roll the dice, and x or + to get your score. Keep a running total. Doubles or scoring a multiple of 100 earns an extra turn. First to 1000 wins. Play with 10, 12 or even 20 sided dice to increase challenge. pic.twitter.com/GG9R5SKKAR

**Running the Facts** Write a set of “facts” — e.g., “the doubles” in this example — without the answers, on paper. Children figure out the answers — and decide where to write them on the sidewalk or driveway. (If inside, they can make another set of cards with the answers, and place those around the space they’ll be playing in.) To play, flip a card with a fact and run to place it on the answer. Repeat until all the cards are placed. At the end, double check that the cards are correctly placed. Try to improve your time.

**Measuring with Non-Standard Units **How long is your [arm, leg] if you use your socks to measure? How many socks tall are you? What if it doesn’t take an exact number of socks? Challenge: Do you think it will take more of your socks or Dad’s socks to measure your height? Why do you think so? Can you estimate how many of Dad’s socks it will take? How would you think about that?

I can’t remember where on Twitter I saw the suggestion of measuring heights with socks (for ks1) but it went down very well here. Led to some discussion of quarters of socks and odd and even numbers. #tmwyk pic.twitter.com/n9oq36qwwl

**Acting Out Ten In Bed **Find a story or song about a group that grows or shrinks by 1 (e.g., Ten in Bed). Ask your child to act it out, and figure out how many after each one comes or leaves. Challenge: Can you show it on paper? Older children can do the same for a story about a group that grows in a different way (1+2+3+4+5), for example, “How many fruits did the Very Hungry Caterpillar eat by the end of Friday?” Or, “When all of the animals were together, how many were on the journey in Rooster’s Off to See the World?” (This story reverses midway, with groups of 5, then 4, then 3, then 2 leaving.)

Today we have used the number rhyme ‘10 in a Bed’ to practise finding 1 less. Could you use your teddies to practise this too? Can you write the number sentences to match? Here is a link to the rhyme so you can sing along…..https://t.co/S5UXurBSh9#CPSpelican #CPSPhoebe pic.twitter.com/VkeOOC9YgT

It's a street maze! To play..

1. Start on the 1 in the bottom centre square

2. Then, jump 1 space in any direction (F,B,L,R) but NOT diagonal.

3. You can jump in any direction the number of squares indicated by the square you’re standing on.

**Fermi Problems **Sometimes, we wonder about “maths problems we will never know the exact answer to” (according to genderi.org/enrico-fermi-b,) – otherwise known as Fermi problems. Look for opportunities to ask such questions and think about how you would estimate an answer to them.

We are harnessing our inner Fermi’s and starting some estimation problems around our house based on comments that get made… let’s see what we come up with throughout the day! #iteachmath #brokencamera pic.twitter.com/BV9uX3ID3r

**Measuring with Nonstandard Units **Use a non-standard measurement unit (e.g., same-sized blocks or legos, paper clips, birthday candles, or spoons) to measure things around your home. How can you show what you found on paper? Extension: Find things to measure where there are multiple, different examples (e.g., dandelions in the yard, feet in your house). Put them in order and make comparisons like, “The smallest dandelion was one cube. The tallest was 5. The tallest is 4 more than the smallest.”

**Save Twenty** In this @mathforlove game, players roll dice with the goal of getting as close to (or exactly) 20 without going over. Players roll 5 dice, “save” as many as they like each round, and roll any they don’t save again. After 4 rounds, add the amounts on the dice to get your score. If your total is over 20, your score is 0. Play a set number of games. The person with the highest score wins.

We closed out math time today playing the game Save Twenty. You roll 5 dice. You can save dice and reroll others up to four rolls. If you make a total less than 20 that's your score. If your total is over 20 your score is 0. #tmwyk https://t.co/p4pLuBRYUv

**Find the Numbers and Make a Number Line** Hide numbers around the house for students to find. Put them in order to make an at-home number line!

Today I challenged Jacob to a number hunt around the house. He had lots of fun searching for the numbers and then used them to make his own number line. Could you go on a number hunt around your house?#CPSPelican #CPSPhoebe pic.twitter.com/1jYmaLahrM

**Make a Puzzle **Use the front of a cereal or other box to make a puzzle.

Looking for an easy DIY puzzle? Recycle box tops from your cupboard by cutting the front side into a puzzle. Increase the difficulty of the puzzle by cutting the pieces smaller, or encourage your child to cut his or her own pieces. #joyfulmath #MTBoS #homeschooling #Covid_19 pic.twitter.com/dKN6dSdyiT

**Sums to 100 **Use the numbers 1-9 to make 3 two-digit numbers that sum as close as possible to 100.

OCTM Daily Math Activity: Using the digits 1-9, at most one time each, fill in the boxes to get a sum as close to 100 as possible. Is it possible to get a sum of 100? What was your strategy at first? How did your strategy change with different attempts? #OCTMconnects pic.twitter.com/FA8wj50kHL

**A Nature Hunt** What can you find outside? How many different kinds of things? How many of each kind? Can you make a graph that shows what you found? What does the graph tell you?

Inspired by @Kim_D_ONeal morning meeting to do some graphing this morning. Beau had to find objects first then graph it. Love outdoor math #thecoleway @NISDElemMath @NISDCole pic.twitter.com/wsiPyCZWOu

**Counting Tangerines **Find situations to pose questions about counting. Ask, “How many [pieces of tangerine]? How do you know?” And, “How many [tangerines] total do you think I used? Why do you think so?”

Abuelita arranged these tangerines 🍊 and then asked her 2 grandchildren: “¿Cuántas mandarinas hay?¿Cómo lo sabes?” /How many tangerines? How do you know?” My ❤️ is full!! #countingcollectionsathome pic.twitter.com/QLbMZODvD3

**Sprout ** A game that requires only pencil and paper. Easy enough for the very young, with lots for older children and adults to think about.

Sheltering in place? Try this game, invented in 1967. Read more at https://t.co/IPKwwj5v3k (and so much more at that site!) pic.twitter.com/kfq0834Uh3

**A Number Hunt at Home** What numbers can you find at home? What do the numbers you find represent?

Mrs. Nania went on a math scavenger hunt this morning in her house and found so many numbers! She can’t wait to see what numbers you found! #WhatAreOurSwansUpTo pic.twitter.com/GNlyI7Ehds

**Math & Art **Draw a rectangle with lines breaking it into many different shapes for students to color. They can figure out how many shapes, how many different kinds of shapes, how many of each kind of shape, and how many colors they used. A different challenge: What is the least number of colors you can use to color this space if you can’t use the same colors on adjacent shapes? (graph theory)

Excellent design! we did this too, but did #graphtheory instead: what is the least number of colors you can use to color this space if you can't use the same colors on adjacent shapes … and we ended up with four. (wall was too bumpy; next time sidewalk!) #MTBoS pic.twitter.com/xQU80M6MQG

**A Color Hunt** Children who are beginning to learn about attributes and sorting can sort a set of objects by color, or go on a search for objects to sort by color. Discuss the ones that raise questions, e.g., objects that are more than one color. (Note: This activity comes from:

https://www.dayswithgrey.com/blog/preschool-morning-routines-that-encourage-child-led-learning.)

Morning #tmwyk, taken from Days with Grey (https://t.co/o2zPAZRM0A). "The dinosaur is purple, but the wheels are orange!" "Okay, so where will you put it?" [Thinks and inspects the toy, turning it over and around] "Purple!" We also talked about which color has the most objects. pic.twitter.com/xLmXgoTczb

**Shape Hunts** Students can look for 2-D shapes, 3-D shapes, shapes with [4] sides, shapes with [6] faces, or [triangles] or [cubes].

Hey Kindergarten #irascholars ! We are identifying and describing 3D shapes in math… cubes, cylinders, spheres, comes and pyramids! Check out the examples of these Teagan Davis of these around her house! Tag us in pictures of your 3D shape hunt! pic.twitter.com/s8rTh2zF9c

**Drawing Shapes** Challenge your child to draw different shapes. You can ask for a particular shape – “Can you draw a square?” – or for a shape with a particular attribute – “Can you draw a shape with 3 straight sides?”. Extension: Draw as many different examples of shapes with 4 sides you think of. What makes them different? How many can we name? (Printable dot paper. Do the activity online.)

#learningfromhome with quadrilaterals yesterday with my daughter. I asked her to try and draw different 4-sided figures. Which one do you think she had the most trouble drawing? pic.twitter.com/2Qg3eu2zgr

**Pairs of Socks **After sorting and pairing the family’s socks, count how many pairs and how many leftovers without a partner? An extension: if we have [#] pairs of socks, how many socks are there altogether? How do you know? What if we added in the socks without a parnter?

Sock Sorting Party! How many socks? How do you know? The 9 year old made an array but counted by 2’s. He got two different numbers. Still working out why. 🤔 #Counting collectionsathome #tmwyk #MTBoS pic.twitter.com/sX3FtXWW4C

**Dominoes **If you have a set of dominoes, make a sheet with areas for 1-18. The task: find the total number of dots on each domino, and place it beneath that sum. (Extension: Record an equation for each domino after you’re done. Extension: Is there more than one equation you could write? eg 7 + 7 =14, 3+1+3+3+1+3=14)

A simple math activity for K-2 (depending on which dominoes you choose) Subitize and add the dots on each dominos and then sort into categories based on sum. @Hubbard_School @TisdaleSchool pic.twitter.com/WPkfiZZTrJ

**Counting Coins** Give your child a set of coins. Younger students can sort them into groups, count how many are in each group, and name the groups (e.g., pennies). Slightly older students can figure out how much money is in each group and how to write it. Older students can figure out how much money there is altogether and how to write it. Discuss the value of each coin and relationships between the coins. Extension: How many different ways could you make [.25¢]? Do you have them all? How do you know?

Counting coins is a great way to practice counting, adding one and two digit numbers, beginning level financial literacy, and even decimals! This is my 1st grader making values 3 different ways. #iteachmath pic.twitter.com/G5pycFRmxE

**Make a Calendar. **Challenge children to write the numbers 1-[31] on sticky notes and make them into a calendar on a large piece of paper labeled [March]. Younger students might need the days of the week written in, and the 1st sticky note placed for them. Older students can be challenged to figure those pieces out by themselves.

Today my girls and I created a calendar! Give it a try at home. I just used post its and poster letters. They worked together to make it! It really helped to give us some structure today. pic.twitter.com/sqa0VMvdKn

**A Shape Hunt** Going on a hunt for shapes around the house is a great geometry activity. (Students might submit photos to their teacher, view others’ work in a google classroom, or bring what they found to a video-chat. Open the Tweet below to read the whole thread.)

3D #shapes are everywhere! We went on a #shape hunt today as we searched our homes and then #recorded our findings! Can’t wait for them to #share tomorrow morning when we meet! #bozzisbunch @Inv3_Math #shapehunters pic.twitter.com/aRkEFL1H8S

**Talk Math about Our Class **Show a picture of some or all of the students in the class. (Or have children draw a picture of all or some of their class or family.) Ask, “How can you use math to talk about it?” (For example, children might notice how many students are wearing glasses; how many classmates are missing; or how many eyes there are. Older children might be challenged to think about what fraction of the class is pictured or has black hair.) Extension: Challenge students to write a story problem about the picture and solve it. (Teachers who are collecting students’ work can turn these into a future assignment.)

Asking my KK 218 kiddos to look at this collection of their self portraits. How can they use math to talk about it? Count the eyes, smiles, blue shirts, brown hair. So many ways to count and share. @BlanchardMemAP @BlanchardMem @Inv3_Math @ablearns pic.twitter.com/25eWA6J6bh

**How Many Legs?** Children can be challenged to count the legs on the humans at home; the legs on all of the things that are alive (i.e., including pets); *all of* the legs in the house including things that are not alive (i.e., tables and/or chairs). (Note: This activity is a slight adaptation of one from https://exemplars.com/.)

Day 2 of school at home – here is a twist on an @Exemplars question we love:

Chairs have legs. People have legs. How many legs are in your house?

For our kiddos – share your thinking in @Seesaw!#distancelearning #remotelearning pic.twitter.com/0fYdJbkloh

**$1.00 Words** If A = 1¢, B = 2¢, C = 3¢ … and so on, can you find a word that equals $1.00? There are 7 examples in the tweet below, to get you started!

Ahh, $1.00 words. Here's a sentence with every word worth $1.00: Whenever Henrietta whistled, costumed elephants merrily performed. Maybe ask kids to draw a picture of that. A virtual $1.00 word art show opportunity!!! https://t.co/gPLJuLOZRi

**Where Would [#] Go on the Number Line? **Draw a number line that goes from 0 to — depending on the age of the child — 10, 100, 1000, etc. Ask “About where do you think [5, 10, 100] would go? Why do you think so?”

Where does 1 billion go?#mtbos pic.twitter.com/srA8umAFsx
