#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

**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

**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.

**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.)

**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

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
