  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.
