Number Sense: Games Up to 20

Ages 4–6 · 16 minutes · Math

Play games that reinforce number sense for numbers up to 20

In this lesson, students will get more comfortable with the numbers up to 20. They will practice counting objects, they will compare the sizes of groups, and they will fill in the blanks in sequences. Reinforcing these skills will support them as they move on to learn about the numbers up to 100.
