Problem set #2.
I wrote these problems to find out more about the children’s understanding of base-10 concepts.
1) For Valentine’s Day, Emilio got 4 rolls of candy. Each roll had 10 candies in it. How many candies did Emilio get altogether?
2) Sunny has 16 pieces of chocolate. Just to be nice, her friend gives her 20 more pieces of chocolate. How many pieces of candy does Sunny have now?
3) Jack has 30 dollars. How many more dollars does he need to have 45 dollars to buy a new bike?
4) Daniella has 55 tropical fish. She wants to put 10 fish in each bowl. How many bowls does she need for all of the fish?
