Grade 1 Math at Home

Welcome! We’ll update this page every weekday with a new math activity. Many of the activities will be fun and worthwhile for students of all ages so that you can do them as a family. The following day, we’ll share examples of how other people did the activity so you can check your work and stretch your thinking.

The resources on this page focus on the major work for first grade:

  • fluency with addition and subtraction facts within 10; doubles through at least 6 + 6

  • addition and subtraction with teen numbers

    • adding 10 to make teen numbers (3 + 10 = 13)

    • subtracting 10 or ones from teen numbers (16 – 6 = 10)

  • solving story problems that involve adding and subtracting beyond 20

We’ll do a lot of work with shapes and patterns, too!

Rubbing soapy hands together at the sink.

Math in Our World: A Soapy Situation

It’s important to wash your hands to keep them clean.

I like to slowly count when I wash my hands. That lets me know that I spent enough time using soap and water.

Sometimes I count to 20.
Sometimes I count to 10, and then I count to 10 again.
Sometimes I count to 15, and then I count to 5.

  1. Show what’s happening using numbers, math words, objects, or pictures.

  2. What do you notice? What do you wonder?

  3. What math questions can you ask about this situation?
    Answer the questions that you can!

How could you get started?

  • Think about two numbers you can add together to make 20.

  • If you’re stuck, use 20 small objects. Put the objects into two groups and count how many are in each group.

  • Think about counting to 10 and then counting 10 more. What happens if you change the first number to 11? How does that change the other number you count to?

  • Feeling creative? Try skip-counting! You can count by 2s, 5s, or 10s while you wash your hands. Can you say the first 20 numbers in your skip-counting pattern?


  • Can you come up with a different way to count each time you wash your hands?

  • The next time you wash your hands, show someone else how you’re counting. Use numbers and math words to explain your thinking.

  • Ask if they have any other questions you can answer!

Follow Up

Can you think of other ways to use math while you wash your hands? Think about counting backward or counting by tens. Maybe you know a math song that takes about 20 seconds. We’d love to hear your ideas!
