Day 83: Composite Figures Study Guide & Quiz

6th Grade Math Standards: 6.G.1 Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.
MA.1.a.Use the relationships among radius, diameter, and center of a circle to find its circumference and area.
MA.1.b. Solve real-world and mathematical problems involving the measurements of circles.

The Learning Objective: Find the area of a composite figure

Quote of the Day: “I’ve noticed an interesting thing. When some star players are interviewed after a game, they say we. They are part of the team and think of themselves that way. When others are interviewed, they say say I and they refer to their teammates as something apart from themselves - as people who are privileged to participate in their greatness.” - Carol Dweck

Question from Yesterday (as always from a student): Is it ok to find the area of a square and then multiply that by 5 if they are all the same size?

Assessment: The composite figures quiz. I saw lots of common mistakes such as not dividing by two or not being to find the correct base and height of a figure.

Agenda:

1. Composite figures study guide #1 & #4
2. Quote, Star Student, Question of the Day
3. Partner up and do the problems 5, 6, 7, 8 , and 9
4. Take the quiz (second part of class)
5. Start and fix the weekly quiz

Glass-Half Full: The way in which the study guide was done was appropriate. We reviewed key concepts from the study guide rather than the whole study guide which would have taken too much of our time.

Regrets: The 6th problem on the study guide required students to multiply 16.5 by 21 and this distracted students from the primary hard part of this problem which was identifying a base and height. It took too long and could have been a difficult problem if the numbers were 3 and 5. I need to go back and change these numbers in the future.
