Solve the problem using 3 different representations of pictures, words and numbers.
Review the solution and determine if it is reasonable.

4. Working together
In groups of 2 to 3 students, share your response with your group members
Each group will then create a “Final Copy” on chart paper of the strategy you choose to share in your group. It can be one of your group member’s strategies or a combination of all strategies.
When everyone is done, we will share your final copies with the whole group

5. As students share, answer these….
What connections do you notice between the different representations?
Which representation appeals the most to you? Why?
How do different representations help you make sense of the problem?
