Composing & Decomposing High School Examples
High School Example:
Compose 3D shapes into other shapes, ie. nets
Factoring via Area Model (connected to visualizing)
Function operations, all up to function composition in Calculus.
Composing and decomposing numbers connects to algebraic expressions in high school. Providing examples of squares and rectangles that have known dimensions provides students with the ability, to begin with the familiar as they move toward algebraic expressions where the size of the area is unknown.
Sort the following. Be prepared to describe how you sorted:
Make a rectangle using more than 3 tiles.
How would you describe the dimensions of your rectangle and the area of your rectangle?
