Square Number Facts
Square Number Facts
Purpose
Name square number facts 12 through 102
Materials
Optional use of diagrams of a 1 × 1 square, 2 × 2 square, 3 × 3 square for student reference
Overview
Ask students to complete square number facts such as 42, 52, 62, 72, and so on.
As in previous activities, you might use name cards to randomize who is selected to answer. This should keep students’ attention, ensure a quick pace, and provide lots of practice when working with a small set of selected facts at a time.
About the sequence
Part 1 asks students to name square number facts 12 through 52. Part 2 moves on to naming square number facts 62 through 122 and encourages students to look for patterns associated with square numbers.
Part 1
Let’s work on some square number facts by squaring numbers 1–5:
Examples:
- 12 (1)
- 22 (4)
- 32 (9)
- 42 (16)
- 52 (25)
If it’s helpful for children to visualize squaring numbers, have 1 x 1, 2 x 2 and 3 x 3 squares available in the classroom for reference.
While children are enjoying their building of mastery, feel free to repeat. When children are eager for more, try Part 2.
Part 2
Let’s work on some more square number facts. This time we’ll incorporate squaring numbers 6–12.
Examples:
- 62 (36)
- 72 (49)
- 82 (64)
- 92 (81)
- 102 (100)
- 112 (121)
- 122 (144)
