Area of triangle (starter- times tables + rectang
Here you get 1hour lesson: a presentation, ext-support-expected worksheets, a snap game and 1cm^2 transparent grid that can be printed on A4 tracing paper to measure area by counting. This was my interview lesson with Y7 kids, but use the snap game for older kids. Differentiated, focuses on functional skills and retention of the formula. The starter - times tables, or the area of a rectangle.\nSNAP - 1st page is the back side (goats have rectangular eyes, link with area of rectangles). I insist b and h are perpendicular, hence the sign). Have fun.
