We have been using our knowledge of number bonds to 10 to solve number bonds to 100 with multiples of 10.
If I know 3+7 = 10, I know 30 + 70 = 100.
Play these games to reinforce this knowledge.
Choose Number Bonds, then Make 100 (tens)
There are also number bonds to 10 and 20 which would be useful revision.
