CHAPTER 8: MEASUREMENT

Lesson 8: Counting Square Centimetres

Goal

Estimate, measure, and compare areas using square centimetres.

Instructions for Use

Area Explorer allows students to demonstrate an understanding of area of regular and irregular shapes.

To use Area Explorer, look at the shape on the grid. Count how many squares are coloured and use that to determine what the shape’s area is. Type your answer into the white box and click “check answer” to see if it is correct. Click on “Draw New Shape” to see another shape on the grid. If you want to try working with a larger shape, increase the number for the shape’s perimeter.

Exploring Area allows students to determine and record area.

To use Exploring Area, click on “recording sheet” to print out the worksheet for the activity. Work through the seven questions on the worksheet to explore how area changes depending on length and width.
