1. Solve a Simpler Problem Lesson 5-6

2. Strategy When a problem contains difficult numbers (like fractions or mixed numbers), then imagine the problem with simpler numbers. Solve a problem using the simpler numbers. Check to see if the strategy worked. Does the answer make sense? Go back and use the same strategy, only this time you can use the more difficult numbers.

3. If you get stuck… Remember, there are only four operations to choose from: multiply, divide, add, or subtract. Try a few operations and see which answer makes the most sense.
