1. Mathematical Problem-Solving Understand the problem Devise a plan Carry out the plan Look Back

2. The Mathematical F-Word

3. Fractions! 1/2 + 1/4

4. Understand the Problem Can you state the problem in your own words? Can you restate the problem using a diagram, table of values, or words?

5. Identify what is known. Identify specifically what the problem is asking for.

6. Devise a plan Have you previously solved a related, easier problem? Can you devise a related, easier problem and solve it?

7. Look for a pattern Make more tables, drawings, etc. Guess (!) and check.

8. Can you state the problem in your own words? One fourth plus one half One quarter plus one half

9. Can you devise a related, easier problem and solve it? One shovel plus one pencil One bird plus one bird

10. Add: two cows plus one cows. Add: two shovels plus one shovels. Add: two cows plus one shovels.

11. Add: two snoitcarfs plus one snoitcarf. Add: two viertels plus one viertel. Add: two fourths plus one fourth.

12. Two fourths plus one fourth versus 2/4 + 1/4

14. Every half is equal to two fourths So, one fourth plus one half is the same as one fourth plus two fourths
