1)Solve the problem with any kind of math model and explain what your math model represents. Line AE is a straight angle. Angle ABC is 42 degrees. Angle CBD is 33 degrees. What is the measure of angle DBE? 2) Create a circle map to show everything you know about division. Divide your circle map into 4 quarters: Top left corner: definition in your own words Top right corner: words that are related to division Bottom left corner: Number examples Bottom right corner: Picture examples 3) Use bar modeling to answer the following question. Explain how and why you have set up your bar model. There are 5 times as many children as adults at the Fall Carnival. There are 422 adults. How many people total were there at SAS Pudong for the Fall Carnival? 4) Draw a comic strip that will explain to the fourth graders (who are just starting to learn how to do division) the purpose of division. 5) Complete IXL for 20 minutes, doing an activity recommended for Unit 4 noted on the teacher blog or a higher, more challenging activity. Parent signature: ___________ The activity(ies) I did were: Grade ____ Activity _________ 6) Please ask your teacher for the “HALF THE JELLYBEANS” story. After reading the story, explain what is wrong with the main character’s mathematical thinking. Is there any humor in the story? Explain why. 7) Mrs. Rekate was in Chicago last week.
