Strings and Areas
You'd be surprised what you can do with a string! The constraint is the length of string, and the task is to maximize area. Given a series of composite shapes, learners must create a formula for the maximum area for a specified...
Lesson Planet: Curated OER
Area of an L-Shape
Think about your shapes as tangrams as you find their areas! Scholars learn to decompose L-shaped compound figures to find their areas. A video shows how to break the figure into rectangles, and learners practice using the included...
Lesson Planet: Curated OER
Area of Compound Shapes
Composite figures—because everything isn't shaped like a rectangle, triangle, or circle. Learners practice separating compound shapes into something more manageable. A video shows them how to make the calculations, and worksheets give...
