Squares, Cubes, and Roots: Grade 6 math
This topic covers calculating squares, cubes, and their corresponding roots. The worksheet reinforces mental recall of common values and estimation of non-perfect roots.
What this covers
Squares, Cubes, and Roots is taught in Grade 6 (age 11 to 12) as a topic to introduce. It sits in the Number strand.
Worked example
Calculate 5^2 + sqrt(64).
- Evaluate the square: 5^2 = 25
- Evaluate the square root: sqrt(64) = 8
- Add the results: 25 + 8 = 33
Answer: 33
Difficulty scale
The sheet generator offers five difficulty settings for this topic.
- Squares of integers from 1 to 12
- Square roots of perfect squares up to 144 and cubes from 1 to 5
- Cube roots up to 125 and mixed order-of-operations with roots
- Higher squares up to 20^2, cubes up to 10^3, and fractional roots like sqrt(14)
- Estimating non-perfect square roots between consecutive integers
Common mistakes
- Multiplying the base by 2 instead of squaring it (e.g. 5^2 = 10)
- Halving a number instead of finding its square root (e.g. sqrt(36) = 18)
