1. Mathematics Extended WEEK 3 LESSON

2. Recap… (Perimeter) Perimeter is measured or calculated length of the boundary of the shape . The perimeter of a circle is its circumference . Perimeter is the sum of all sides .

3. Recap… (Area) Amount of space it occupies. Measured in square units. Surface Area = Sum of Area of its faces Area of basic shapes is calculated using a formula.

4. Recap… (Volume) Amount of space it fills up. Measured in cubic units Volume of cuboids and prisms can be calculated using a formula.
