DURING TEAM WORK… I work cooperatively with my team members to accomplish a particular goal by: Performing assigned tasks/roles Listening to my team members Respecting the ideas of others Being a helpful contributor to the team.

Entry How can you figure out the size of a part of a part without having to draw a diagram? Work with your team or your class to explore this question as you consider the example of 2/3 * 4/5. Describe how you could draw a diagram to make this calculation. If you completed the diagram, how many parts would there be in all? How do you know? How many of the parts would be counted for the numerator of your result? Again, describe how you know. How can you know what the numerator and denominator of a product will be without having to draw or envision a diagram each time? Discuss this with your team and be prepared to explain your ideas to the class.

Entry PARTS OF PARTS, Part 2 Work with your team to find each of the following parts of parts without drawing a diagram. For each problem, explain clearly why your answer makes sense. of of

Entry Andy and Bill were working on finding of.. They started by drawing the diagram in the book. Suddenly Andy had an idea. “Wait!” he said, “I can see the answer in this diagram without having to draw anything else.” Discuss with your team what Andy might have been talking about. Be prepared to share your ideas with the class. Use your diagram to find of and of. Work with your team to find other examples of fractions that could be multiplied using a simple diagram like Andy’s.

WHEN I STAND AND DELIVER… I go quickly to the white board when it is my turn. I print my name on the white board neatly and complete the assigned task on the white board. I complete the problem as a notebook entry if it is not my turn to be at the board. I stand at attention to show my teacher when I am done and requesting permission to be seated. I address the teacher as “sir” or “ma’am”. I ask or answer a question in a clear, loud voice.

Entry 24: Stand and Deliver at board I will call out problems out loud One person from each group at a time goes to the board, prints their name on the board, listens to the problem and copies it down and solves it Everyone else copies the problem onto their notebook as an entry – Resource Manager – Facilitator /Timer – Recorder/Reporter – Task Manager/Justifier

Entry 24: Stand and Deliver Write each of the mixed numbers below as a fraction greater than one, and write each of the fractions greater than one as a mixed number. Include a diagram to explain each answer. 1.3 ¼ 2.4 4/5 3.23/4 4.15/2
