THE CURIOSI · EXPLORE & TRY

Explore the picture together. Open each numbered card for a little help.

Look at each counter or step. Open the explanations to connect the picture and the equation.

1Start with 8

Eight purple counters leave two spaces in the first ten-frame.

2Split 5 into 2 and 3

Two of the five green counters fill those spaces. Three go into the second frame.

3Ten and 3 make 13

8 + 5 = 8 + 2 + 3 = 10 + 3 = 13.

Count carefully and explain your steps. Use objects or fingers whenever they help.

Show the total for 8 + 5. Notice a full ten-frame and three more. Tap a box to add a counter; tap it again to remove it. Each frame holds ten.

0 counters selected.
