In your own words, explain what a polygon is. Draw two examples. Then, in your own words, explain what a parallelogram is. Draw two examples.LESSON 31: MATH JOURNAL Directions: Find the missing factor by rolling the die or choosing a number card. Record the missing factor in one of the problems below and then solve. When fi nished, circle the facts that were the easiest for you to solve. Directions: Using the quadrilateral sheet, cut out the shapes and place them where they belong on the Venn diagram below. Label each circle and the intersection.LESSON 32: APPLY Directions: Tear out this page and cut out the quadrilaterals. Sort them and glue them onto the Venn diagram. QUADRILATERALS Directions: Write a defi nition of a trapezium in your own words. Compare your defi nition with a partner’s. Directions: Tear out this page and cut out quadrilaterals to use for your quadrilateral image.LESSON 33: APPLY Directions: Once your picture is complete, fi ll out the bar graph below.LESSON 33: APPLY, continued Directions: Refl ect on your learning. Write two statements about the data in your bar graph. Then write one question that could be answered using your graph.LESSON 33: MATH JOURNAL Directions: Find the missing factor by rolling the die or choosing a number card. Record the missing factor in one of the problems below and then solve. When fi nished, draw a rhombus around the fact that was the most challenging and a trapezium around the easiest fact.LESSON 34: CONNECT Directions: Follow the steps below.1. Read the problem and then build the garden plot using the small squares.2. Draw the garden plot on the grid paper. (Hint: You can place your squares on the grid to help you draw the outlines of the garden plot.)3. Find the total area of the garden plot (array).4. Repeat for all garden plots.LESSON 34: APPLY 1. If Jana, Omar, Youssef, Nadia, and Aya all put their gardens together, what would be the total area? How many total square units would they need?Directions: Refl ect on your learning. How is fi nding the area of garden plots similar to solving multiplication problems? Explain your thinking in the box below. You may also use pictures. Directions: Look at the puzzle below. How many rectangles can you fi nd? You may color or number them (or use another method) to help you keep track.LESSON 35: CONNECT Directions: Determine the area of each rectangle. Explain the strategy you used in the work space provided next to each shape and record the answer.LESSON 35: APPLY These gardens are not rectangular. Can you fi nd the area anyway? Show your thinking. Directions: Solve the following problem: Mohammad makes a drawing with 5 squares. Mona makes the same drawing but uses triangles. It takes 2 triangles to make a square. How many triangles does Mona draw? Directions: On the grid below, draw and label as many rectangles as you can with an area of 18 square units. Then write equations that match your rectangles.LESSON 36: APPLY LESSON 36: MATH JOURNALOmar planted two fl ower plots. One was 3 × 4 and one was 2 × 6. Do they have the same area? How do you know? Show your thinking in numbers and pictures in the box below. Directions: Play Mystery Multiplication. Select two number cards, create an array using the two numbers as your factors, write the equation, and then fi nd the product.LESSON 37: CONNECT Directions: Determine the total area of each shape.LESSON 37: APPLY Directions: Refl ect on what you have learned about area. Then answer the following questions using words and pictures.LESSON 37: MATH JOURNAL Directions: Split the arrays below into at least 2 smaller arrays. Label the factors for each part. An example is shown below. Directions: Play Mystery Multiplication. Select two number cards, create an array using the two numbers as your factors, write the equation, and then fi nd the product.LESSON 39: CONNECT Directions: Break apart the arrays and, using the distributive property, write an equation to show your work. LESSON 39: APPLY LESSON 39: MATH JOURNALWhat is the Distributive Property of Multiplication? Explain it in your own words. Use drawings and numbers to explain your thinking. Directions: Break up the following arrays in as many diff erent ways as possible. Use diff erent colors to keep track of your diff erent arrays. Then select the one that is most helpful to you as a mathematician and write the equations that match it in the box. LESSON 40: APPLY
