Pip the Bunny says:
“When numbers go up to 20, split them into Tens (T) and Ones (O)!”
Lesson 1: Stacking Tens (T) and Ones (O)
For 12 + 5, split 12 into 1 Ten (10) and 2 Ones (2)!
Add Ones first: 2 + 5 = 7. Then keep the 1 Ten = 17!
Lesson 2: Put Big Number in Your Head!
For 14 + 3: Keep 14 in your head and count forward 3 fingers: 15, 16, 17!
