For example, 8 is a cube number because 8×8×8=512 Square Root: The number that when multiplied by itself gives the original number. For example, the square root of 4 is 2, because 2×2=4.

Question: What are the next three square and cube numbers after 1, 4, 9, and 16? Clues: • Square numbers are numbers multiplied by themselves, and cube numbers are numbers multiplied by themselves three times. • Square numbers follow a pattern of increasing by odd numbers: 1, 4 (1+3), 9 (4+5), 16 (9+7). • Cube numbers follow a pattern of increasing by even numbers: 1, 8 (2x4), 27 (3x9), 64 (4x16). In pairs: Select and solve one of the tasks: A. Work in pairs and write down the next three square and cube numbers. B. Work in pairs and explain your solution through a drawing.
