Our second graders are digging in deep to solve word problems that use two or three digit addition subtraction and addition. We have learned how to use comparison bars, math mountains and equations to solve these problems. The most important task that we need to remember is to visualize what the problem is asking for, slowing down to understand what is being asked. Here are just a few examples of what we have learned:
Word Problem #1 ( Comparison Bars)
David has 46 marbles. He has 13 fewer marbles than Ellery. How many marbles does Ellery have?
Word Problem #2 ( Two Step Word Problems)
Kiara has 2 cartons full of cereal boxes. Each carton contains 12 cereal boxes. She sells 17 cereal boxes. How many are left?
