Adding to 10: I can add two groups and write a number sentence.

1. Mei has 4 pears.

   Kofi has 1 pear.

   Picture: Mei's: 4 pears and Kofi's: 1 pear.

2. Put the pears together. That is adding.

   Count them all: 1, 2, 3, 4, 5.

   4 + 1 = 5

   Picture: Mei's: 4 pears and Kofi's: 1 pear. The groups are pushed together and counted. 5 pears altogether.

   Picture: Two groups of frogs: 2 and 1.

   Choose one:

   • 2
   • 3
