Materials: Two-color counters, 12 for each student
1. Have students fill the ten-frame with yellow counters. Have them put one red counter below the frame.
Ask: What is 10 plus 1? Have students write 11. Do 10 + 2 similarly.
2. Have students put 9 yellow counters in the ten-frame and 2 red counters below. Ask: What addition do
the counters show? 9 plus 2 Then have students move one red counter to fill up the ten-frame. Ask:
Nine plus 2 is equal to 10 plus what number? Have students write 1. Ask: If 10 plus 1 equals 11,
then what is 9 plus 2? Have students write 11 for the sum 9 + 2.
3. Have students put 8 yellow counters in the ten-frame and 4 red counters below. Ask: What addition do
the counters show? 8 plus 4 Then have students move two red counters to fill up the ten-frame. Ask:
Eight plus 4 is equal to 10 plus what number? Have students write 2. Ask: If 10 plus 2 equals 12,
then what is 8 plus 4? Have students write 12 for the sum 8 + 4.
