How many squares are there on a standard checkerboard (8x8)?. Think of it on a smaller scale before jumping to the answer …. 1. = 1 1x1 square. 1. = 4 1x1 squares. 2. = 1 2x2 square. 5 squares. 2. Think of it on a smaller scale before jumping to the answer ….

How many squares are there on a standard checkerboard (8x8)? Think of it on a smaller scale before jumping to the answer … 1 = 1 1x1 square 1 = 4 1x1 squares 2 = 1 2x2 square 5 squares 2
Think of it on a smaller scale before jumping to the answer … = 9 1x1 squares = 4 2x2 squares 3 = 1 3x3 squares 14 squares 3
Think of it on a smaller scale before jumping to the answer … = 16 1x1 squares = 9 2x2 squares = 4 3x3 squares = 1 4x4 square 30 squares total
Do you see a pattern? What is it? …. The sum of the squares … So … an 8x8 checkerboard has 8x8 + 7x7 + 6x6 + 5x5 + 4x4 + 3x3 + 2x2 + 1x1 squares = 64 + 49 + 36 + 25 + 16 + 9 + 4 + 1 = 204 squares
