Grade 4 Mathematics - FAST Success Kit
This kit helps students master calculating perimeter (the distance around a shape) and area (the space inside a shape). Students will learn formulas for rectangles, solve problems with composite figures like L-shapes, find missing side lengths, and apply these concepts to real-world word problems. These skills are essential for geometry success on the Florida FAST assessment.

Complete solutions
Calculate perimeter of rectangles using P = 2l + 2w or P = 2(l + w). Understand perimeter as the distance around a shape.
Calculate area of rectangles using A = l x w. Understand area as the number of square units that cover a shape.
Break apart L-shapes and other irregular figures into rectangles, then add or subtract areas to find the total.
Use perimeter or area to work backwards and find unknown dimensions of rectangles.
Apply perimeter and area concepts to real-world situations like fencing gardens, carpeting rooms, and covering surfaces.
Understand that perimeter is measured in linear units (cm, m, ft) while area uses square units (sq cm, sq m, sq ft).
