Perimeter, Area and Scale Factors for Length, Area and Volume
Start here
Focus on area and perimeter of 2D shapes including circles. Open support for “Calculate Sides and Areas of Similar Shapes Using Area Scale Factors”, then explain the idea in your own words.
Year 8 learners practise area and perimeter of 2d shapes including circles.
The activities include Calculate Sides and Areas of Similar Shapes Using Area Scale Factors, Calculate Sides and Volumes of Similar Shapes Using Volume Scale Factors, Find the Area of a Circle, and related practice. The checked support below includes teach, practice, video, teaching. Open a resource in its provider's website and choose the format that best helps the learner explain the idea independently.
