#### People share 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.

**October 9, 2020 (Math for the Neighborhood)**

When we say “math for the neighborhood” we are thinking of something Math with Me MN calls “Public Math.” They are encouraging people to create and share friendly, approachable activities, in their homes and communities; activities “designed to connect people to each other and to mathematics” and “to reignite joy and play in (distance) learning, and to maximize student agency.” Examples we’ve seen below; lots more of examples @MathWithMeMN. Also, #MathWalk, #SidewalkMath, #PublicMath

Sharing my math love with my neighborhood today! #dg58pride pic.twitter.com/7t6bP3bF1f

I made natural, biodegradable chalk paint to math-up a walkway for the younger children in our neighbourhood.

Equal parts cornstarch and water and for this colour I added turmeric. #publicmath #sidewalkmath #sd38learn pic.twitter.com/FMi0P6JQc7— Janice Novakowski (@jnovakowski38) April 8, 2020

**Before and After.** This game helps children practice what number comes before or after another number – or what’s one more (or less) than a number. You can write the number instead of rolling a die. Older children can practice what’s 10 or 100 more or less than a number.

https://twitter.com/JovanDM/status/1245722722963009536?s=20

**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?

**Toilet Paper Math** This thread of Tweets shows how one jumbo package of toilet paper can present a context for multistep problems. 1) How many rolls? How do you know? 2) How many packs?

**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.)

**Perimeter Around the House **Can you use your hands or feet to measure the perimeter — the length around the edge of an object — of things at home? What if you measure the same thing first with your feet, then with your hands? Which do you think will give the bigger/smaller result? How much bigger/smaller? Why?

**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.

**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.)

**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)

https://twitter.com/MrsMains/status/1239910657174253574?s=20

**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?

**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.)
