What’s Included in This 4th Grade Math Unit

This comprehensive unit provides the perfect mix of visual reference pages, practice worksheets, and engaging games to make geometry concepts stick.

Geometry Vocabulary for Math Notebooks (6 pages):
Students glue these reference pages into their math notebooks to use throughout the unit. Each page defines key geometry terms and includes diagrams to reinforce understanding.

Worksheets (10 total):
Students apply geometry concepts to classify and describe polygons. Activities include:

• Identifying quadrilaterals, pentagons, hexagons, and octagons

• Using clues to determine the correct shape

• Sorting shapes by attributes such as sides and angles

• True/false geometry statements

• Diagram-based shape classification and sorting

Error Analysis Pages (4 total):
Students evaluate sample work to identify and correct geometry mistakes. These pages spark math discussions and deepen understanding of common misconceptions.

Emoji Math Sort:
Students use smile and frown emojis to check shape classifications on 48 task cards. It’s an interactive and self-checking review of geometry properties.

Polygon Spinner Activity:
Students use a paperclip spinner to randomly select polygons and keep tallies of which shape “wins.” A fun, no-prep game for practicing shape recognition and vocabulary.

Create Your Own Gym Geometry Activity:
Students design a gymnasium that meets specific geometric criteria, combining creativity with real-world math application. Perfect for fast finishers or enrichment.

Game #1: Fast Draw / Fast Define

Students play in pairs — one draws a geometric figure while the partner guesses the term. A fun way to review and reinforce geometry vocabulary.

Game #2: Race to Sort

Teams race to correctly sort polygons by shared attributes. The first team to finish accurately wins — ideal for whole-class review sessions.

Game #3: Who Took Mr. Fluffers?

A student favorite! Using clues about angles, sides, and shapes, students solve a geometry mystery to discover who stole the classroom cat, Mr. Fluffers. It’s a hilarious and challenging deduction activity.

Game #4: Build a Pizza

Students earn pizza toppings for each correct answer. The first to build their full pizza wins! Chance cards keep gameplay fun and unpredictable.

Game #5: Whole-Class Game – Bucket Filler!

Students solve geometry task cards posted around the room. Each correct answer earns a chance to drop a card into the “bucket.” Winners are randomly drawn for prizes — a great movement-based review.

Game #6: Racing Game – Line Them Up!

Teams compete to line up geometry task cards in the correct order from START to FINISH. Fast-paced and perfect for reinforcing polygon properties.

Geometry Terms Included

Students will learn and apply the following vocabulary throughout the unit:
line, line segment, endpoint, ray, parallel lines, perpendicular lines, intersecting lines, angle, acute angle, obtuse angle, right angle, open and closed figures, plane figure, polygon, side, vertex, properties, circle, triangle, quadrilateral, square, rectangle, rhombus, kite, trapezoid, pentagon, hexagon, octagon, irregular polygon, and congruent figures.

Flexible Classroom Uses

This 4th grade classify shapes unit can be used for:

• Whole-group lessons on geometry concepts

• Small-group intervention or enrichment

• Math centers and partner games

• Homework and review practice

• Early finisher or sub-plan activities

Every page is designed to build deep conceptual understanding while keeping students actively engaged.
