1. Select A Strategy 3.14C select or develop an appropriate problem-solving plan or strategy, including drawing a picture, looking for a pattern, systematic guessing and checking, acting it out, making a table, working a simpler problem, or working backwards to solve a problem

2. Saving Dimes The class is saving dimes to buy a treat for the class. MaryAnn has 10 dimes. Kate has twice as many dimes as MaryAnn. Tim has half as many dimes as MaryAnn and Mike has half as many dimes as Kate has. Johanna has twice as many dimes as Tim and Mike have together. An ice cream party will cost them \$8.00. Do they have enough money? Explain how you know.

3. Understand the Problem • What do you understand about the problem? • Discuss with a partner • How can you restate the problem? • What information do you have? • What information do you need? • How can you represent the problem by drawing a picture?

5. Strategy • How might you solve this problem? • What materials might you use to solve this problem? • Select a strategy: • Simplify the problem • Draw a picture or diagram • Look for a pattern • Write a number sentence • Guess and check • Make a model • Act out the problem • Make an organized list or table • Work backwards

9. Communicate • Is the answer reasonable? • How do you know? • Could you solve the problem another way? • Describe the method. • Is there a more efficient way to solve it? (easier) • Why is this method easier than the one previously chosen? • Could you write another problem that is similar? • Why is this more challenging than the original?
