Reasoning with resources

Yesterday we practised using the Cuisenaire to solve number sentences with a missing number. The last time we used them we found the difference between numbers with ones. Now we were more confident and could use tens and ones.

Today we had a word problem to solve. In the problem Willy Wonka had given us a bag of sweets. He gave us three different types and 8 in total. We had to see how many combinations of the sweets we could find.

How many solutions can you come up with?
