Perfect Squares and Square Roots
Learning Goal: I will be able to...
- represent squares and square roots, using a variety of tools - geoboards, connecting cubes and grid paper (7)
- estimate, and verify using a calculator, the positive square root of a number, and distinguish between whole numbers that have whole number square roots (8)
Success Criteria: I can...
- explain the difference between squares and square roots
- use a calculator to solve square roots
Note:
Finding the square root of a number is the inverse operation of squaring that number.
The perfect squares are the square of the whole numbers.
The square root of a number, n, written below is the number that gives n when multiplied by itself.
