Intervention Lesson I48 Rectangles with the Same Area or Perimeter Materials colored pencils or crayons. Ms. Arellano s class is making a sand box shaped like a rectangle for the kindergarten class. They have 16 feet of wood to put around the sand box. What length and width should the sand box be so it has the greatest area? Each of the rectangles in the grid at the right has a perimeter of 16 feet. Find which rectangle has the greatest area by answering 1 to 3. 1. Complete the table. The formula for area of a rectangle is A w. Rectangle Length Width Area (square units) W X Y Z 2. What are the length and width of the rectangle with the greatest area? 3. What length and width should Ms. Arellano s class use for the sand box? 4. Reasoning Tracy told Tomas that if a two rectangles have the same perimeter, they have the same area. Is Tracy correct? Explain your reasoning. Mr. Katz has 30 carpet squares to make a reading area in his classroom. Each square is one foot on a side. He wants to make the area in the shape of a rectangle with the least possible border. How should he arrange the carpet squares? Intervention Lesson I48 185
Intervention Lesson I48 Rectangles with the Same Area or Perimeter (continued) Each of the rectangles on the grid at the right has an area of 30 square feet. Find which one has the least perimeter by answering 5 to 8. 5. What is the perimeter of Rectangle 1? P 2 2w 2( ) 2(5) feet 6. What is the perimeter of Rectangle 2? P 2 2w 2( ) 2(3) feet 7. What is the length and width of the rectangle with the least perimeter? 8. How should Mr. Katz arrange the carpet squares? Draw a rectangle with the same area as the one shown. Then find the perimeter of each. 9. 10. 11. 12. Reasoning Marco has 36 feet of fencing, what is the greatest area that can he can fence? 186 Intervention Lesson I48
Intervention Lesson I62 Making Line Plots A year is sometimes divided into 1st quarter: January to March quarters, as show at the right. 2nd quarter: April to June 3rd quarter: July to September 1. Take a survey by asking, Which 4th quarter: October to December quarter of the year were you born? Write the number of the quarter each person answers in the grid. Quarter of the Year You Were Born 2. What are all of the possible quarters that can be said? Answer 3 to 7 to make and use a line plot of the data. 3. Draw a line. Below the line, list in order, all the possible quarters that could be said. 4. Write Number of Birthdays by Quarter below the line plot. 5. For each quarter that was said, mark an X above that quarter on the number line. If more than one X needs to be placed above a quarter, stack them in a single column. 6. Which quarter has the most number of birthdays? 7. How many birthdays are after the 2nd quarter? Intervention Lesson I62 213

Intervention Lesson J18 Use a Simpler Problem, Table, and Pattern (continued) Answer 6 to look back at how you solved the problem. 6. Reasoning Was it easier to use simpler problems, a table, and a pattern than it would have been to solve by drawing a picture of 10 tiles in a row? What if there were 50 tiles in a row? Complete each table. Solve each problem. 7. Suppose Mr. Lange had a rope 50 feet long and wanted to cut it into 25 equal pieces. How many cuts would it take? Pieces 2 3 4 5 6 Cuts 1 2 8.
