3rd Grade Magic of Math Unit 6: Geometry, Area & Perimeter

Build a strong understanding of 3rd grade geometry, area, and perimeter with 20 days of hands-on math instruction!

Magic of Math Unit 6 takes students from identifying and classifying shapes to understanding area and perimeter through visual models, manipulatives, partner games, interactive activities, and meaningful practice.

Week 1: Geometry

Students explore:

• Quadrilaterals and polygons
• Attributes of shapes
• Congruent figures
• 2D shapes
• 3D shapes
• Classifying and describing figures

Week 2: Area

Students build an understanding of:

• Area
• Unit squares
• Finding the area of rectangles
• Relating area to multiplication
• Using models to determine area

Week 3: Area & Partitioning Shapes

Students practice:

• Decomposing rectangles
• Finding the area of decomposed figures
• Partitioning shapes into equal parts
• Relating partitioned shapes to fractions
• Applying area strategies

Week 4: Perimeter

Students learn to:

• Measure and find perimeter
• Determine unknown side lengths
• Solve perimeter problems
• Explore the relationship between area and perimeter

This progression moves students from geometry into two weeks of area instruction before finishing with perimeter.

What's Included

• 20 days of lesson plans
• Mini-lessons
• Daily word problems
• Hands-on activities
• Partner games
• Independent practice
