🔢 1st grade Math: how to help at home

What each unit covers

1. 🔢Numbers to 20

   Counting, ordering and comparing numbers to 20, and seeing teen numbers as 1 ten and some ones.

2. 🔟Make 10

   Finding pairs that make 10 (like 6 + 4) with ten frames, fingers and stories. Making 10 is a key strategy for adding.

3. ➕Adding

   Adding to 20 with pictures, ten frames, number lines and short stories, using strategies like counting on, doubles and making 10.

4. ➖Take Away

   Subtracting within 20 by counting back and thinking addition, and solving short take-away and compare stories.

5. ⚖️Equal or Not

   Learning that = means "the same amount as" (not just "the answer is"), and using ≠ when two sides are different.

6. 📏Measuring

   Measuring length with paper clips and cubes, comparing longer and shorter, heavier and lighter, and seeing why same-size units matter.

7. 🔺Shapes

   Naming and comparing 2D shapes by their sides and corners, and 3D objects by their faces and whether they roll or stack.

8. 📊Data & Graphs

   Sorting by one attribute, reading picture graphs and bar graphs, and comparing groups.

9. 💯Numbers to 100

   Reading and building numbers to 100 with tens and ones, comparing them, and seeing that two names can mean the same amount.

10. 🔢Count It Up

    Counting forward within 100, back from 20, by 2s to 20, and by 5s and 10s to 100, plus seeing small amounts at a glance (subitizing).

11. 🍕One Half

    One half means 1 of 2 equal parts. Children share items fairly between two people and see that two halves make a whole.

12. 🕐Hour & Half Hour

    Telling time to the hour and half hour on clocks with hands and on digital clocks.

13. 🦘Jump by Tens

    Finding 10 more and 10 less than a number in their head, subtracting tens, and adding ones or tens to a two-digit number.

14. 📊Picture Graphs

    Reading picture graphs with three groups: how many in each, how many more, how many in all, and which question a class survey can answer.
