MAP 3rd Grade Math
A comprehensive math course designed for third grade students to build foundational skills in numbers, operations, geometry, and data analysis.
Shapes, Area, and Perimeter
Exploring Shapes
Geometry is the study of shapes! In third grade, you'll discover 2D shapes like squares, rectangles, triangles, and circles.
Measuring Perimeter
Perimeter is the distance around a shape. To find it, add up the lengths of all the sides.
Measuring Area
Area tells how much space is inside a shape. For rectangles, use the formula: \( \text{Area} = \text{length} \times \text{width} \).
Real-World Geometry
Use perimeter to build a fence, and area to figure out how much carpet you need for your room.
Key Formula
\[Area = length \times width\]
Examples
Find the perimeter of a rectangle with sides 4 cm and 6 cm.
Calculate the area of a rectangle that is 5 m long and 3 m wide.
In a Nutshell
