Riley says this picture represents 0.26 because the blue squares represent tenths and the red rectangles represent hundredths. 10 blue squares make 1 red rectangle, and 10 times 10 equals 100. Use the drop-down menus to explain why Riley’s reasoning is incorrect.
Riley is incorrect because it should take ___ to make ___ a blue square.
Riley is incorrect because it should take 10 red rectangles to make 1 blue square.
Explanation: Since each blue square represents a tenth (0.1), and each red rectangle represents a hundredth (0.01), you need 10 red rectangles (0.01 * 10 = 0.10) to equal 1 blue square. Thus, the correct representation of 0.26 is not accurately depicted by Riley’s explanation.
