Squares of Numbers — Easy Worksheet 1
Grade 6 · Whoobee Name: ____________________ Date: __________
Answer each question. Every one is about squares, asked in a different way.
How to solve
Squaring a number means multiplying it by itself: 7² = 7 × 7 = 49. A negative number squared is positive: (-7)² = (-7) × (-7) = 49. For a decimal, the answer has twice as many decimal places: 0.3² = 0.09. For a fraction, square the top and the bottom: (23)² = 49. The area of a square is its side squared.
Example
5² = ___
Answer: 25

💡 Look for a number that, used as a factor twice, gives 25. Squaring 5 means using it as a factor twice: 5 × 5 = 25. That means the missing number is 5. (Its opposite, −5, also works, but the question asks for the positive number.)
