Based on the analysis of the image, the task is to identify which cards correctly match a number with its corresponding base-10 block representation (hundreds, tens, and ones).
Here is a summary of the findings:
Top-Left Group:
*
Card 1 (126): Correct. The visual shows 1 hundred, 2 tens, and 6 ones (100 + 20 + 6 = 126).
*
Card 2 (621): Correct. The visual shows 6 hundreds, 2 tens, and 1 one (600 + 20 + 1 = 621).
*
Card 3 (162): Incorrect. The visual only shows 6 ones, which represents 6, not 162. A correct representation would need 1 hundred, 6 tens, and 2 ones.
Top-Right Group:
*
Card 1 (80): Incorrect. The visual shows 8 hundreds (representing 800), not 80. A correct representation would need 8 tens.
*
Card 2 (808): Correct. The visual shows 8 hundreds and 8 ones (800 + 8 = 808).
*
Card 3 (284): Correct. The visual shows 2 hundreds, 8 tens, and 4 ones (200 + 80 + 4 = 284).
*
Card 4 (482): Correct. The visual shows 4 hundreds, 8 tens, and 2 ones (400 + 80 + 2 = 482).
The problem in the image is that some cards are mismatched. Specifically, the card for the number
162 is incorrectly paired with a visual for
6, and the card for the number
80 is incorrectly paired with a visual for
800. All other visible cards are correctly matched.
