Measure area using counting with squares as a strategy
I can use squares to cover the surface and count the area.
Lesson details
Key learning points
- Using squares means that there are no gaps or overlaps.
- Fractions of squares can be added to make whole squares.
Common misconception
Pupils might count a part square - such as a triangle - as one square unit.
The slides show two parts moving together to make a whole square. Cutting out and physically moving the parts is an effective strategy.
Keywords
Area - The measurement of a flat surface. It measures a 2D space.
Square units - A square of a set size used to measure area.
In Cycle 3, pupils are asked to visualise parts of shapes being manipulated to form a rectangle. If they are unable to do so, print out the relevant slides so that they can cut out the shapes and re-form them as rectangles.
