How many ways to make 10?
Gather 10 counters or dry pasta pieces and two small bowls. Split the counters between the bowls. Count each group, then count them all.
Say: “I have 4 here and 6 here. Four plus six makes ten.” Try another split. Draw your groups on paper and write the number sentence.
Check together: Does every split still make 10? Examples: 1 + 9, 2 + 8, 5 + 5.
Adjust it: Start with 5 counters for support. For a challenge, find all the different splits of 10.
Use age-appropriate counters with adult supervision.
