Making 10 and 100: Farmer Daisy's Farm

Welcome to Farmer Daisy’s farm! Her hens lay brown eggs and white eggs, and the chicks and ducklings follow her everywhere. Farmer Daisy always knows how many more she needs to make 10, because she knows her number bonds.

Remember: Number bonds to 10: 1 + 9, 2 + 8, 3 + 7, 4 + 6, 5 + 5. They help with 100 too: 30 + 70 = 100, just like 3 + 7 = 10. For 64 + 36 = 100, the ones make 10 (4 + 6), so the tens make only 9 (6 + 3).

Magic trick: To make 100, make the ones add up to 10 and the tens add up to 9, because the 10 ones turn into one more ten.
