You will need a display of the Two
Ten Frames Master and connecting
cubes or counters. Arrange 8
connecting cubes on the top ten
frame and 4 on the bottom ten
frame. Flash the display on for a
few seconds, then turn it off. Ask:
- What number do you see? (12)
- How many cubes need to move to the 8 to make ten? (2)
- How many are left? (2)
Then turn on the display to confirm students' thinking.
Arrange 10 connecting cubes on the
top frame and 2 on the bottom ten
frame. Flash on the display for a
few seconds, then turn it off. Ask:
- What counters do you see? (12)
- Which organization was easier to count, the first arrangement or this arrangement? (this arrangement)
- Why? (Possible response: It is easy to see the ten.)
Repeat this discussion for several more problems. Such as 7 + 6 and 5 + 7.
C. Ten Frame Flash 
I will show you two ten frames and flash the display on and off. Tell the number shown and how you know.
