In this lesson, we evaluate three claims regarding the ratios and percentages of white squares to black squares on a checkerboard. We explore Peter's claim about the ratio of squares on the top row, Fran's assertion about the percent of white squares in the left column, and Marjorie's statement regarding the first two rows' ratio. Furthermore, we apply map scale concepts through Caroline's and Kellen's scenarios, translating map distances to real-life feet using the given scales. Engage in ratio language to analyze these claims effectively.

CRA PRACTICE 3RD
Peter claims that the ratio of white squares to black squares on the top row of the checker board is 4 to 5. Do you agree with Peter’s claim? Explain using ratio language.
Fran claims that the percent of white squares on the far left column on the checker board is 50%. Do you agree with Fran’s claim? Explain using ratio language.
Marjorie claims that the percent of white squares in the first two rows is 25%. Do you agree with Marjorie’s claim? Explain using ratio language.
CRA Practice Question Caroline was at a playground looking at a map. According to the map scale, 1 inch = 10 yards. Caroline determined that where she was standing was, according to the map, was approximately 5 inches from the slides. About how many feet away from the slides is Caroline in real life? 1 yard = 3 feet
CRA Practice Question Kellen was hiking with his friends and they needed to know how far away their cabin was. The map scale states that 1 inch = 20 yards. Kellen and his friends determined their location was about 3 inches away from their cabin, according to the map. About how many feet are Kellen and his friends away from their cabin? 1 yard = 3 feet
