In this unit, students are expected to be able to calculate the area of a rectangle using whole number side lengths AND fraction or decimal side lengths. The also need to be able to find the area of a triangle, parallelogram, and trapezoid when given the formula.
This unit also includes volume. At this level, students should be able to find the volume of a rectangular prism both by (1) counting cubes and by (2) multiplying the side length using the formula. Counting cubes can be difficult for some students because of the ones that can't be seen. The students do not have to memorize the formulas, and will be given a formula reference sheet for the assessment.
Games, Resources, and Practice Sites:
Volume Shoot game
IXL Volume of Cubes & Rectangular Prisms
Cubes - NCTM Illuminations Resource
Area of a Rectangle - Math Open Reference
Area of Plane Shapes
Volume of Common Solids
Interactive Area
3D Boxes
