Making Two-Dimensional Shapes- Matching Worksheet
Now that your learners recognize two-dimensional shapes, can they find what each half of those shapes would look like? There are seven shapes on this worksheet, bisected by a dotted line. Scholars examine these shapes and match them to a...
Curated OER
Sorting 2-Dimensional Shapes
Some shapes have square corners, and some do not. Scholars participate in a sorting activity as they determine if these 12 shapes have square corners, categorizing them based on this attribute. Encourage geometers to draw the square into...

Which One Could Make This Shape?
Explore two and three-dimensional shapes. Learners first examine three 2-D shapes and determine which of three 3-D figures could have made that shape. The wording here is a bit confusing; make sure your kids understand what it is...
Curated OER
Making Two-Dimensional Shapes
Find the shapes that fit. Pupils explore visual discrimination in a set of geometry worksheets, which has them examine shapes that have been divided in half. They observe a set of shapes to determine which of them would fit into each...

Making Two-Dimensional Shapes
Use this introductory geometry worksheet as a projected warm-up for your class, doing it together and then revealing the explanation on the bottom half. Learners examine a square and a circle, each bisected by a dotted line. They must...
Curated OER
Square Corners
Which ones are square corners? As they learn more about shape attributes, be sure scholars understand the difference between a vertex and a square corner. After examining two examples, learners circle the 90-degree corners in 12...

Geometry 3D Shapes: Test Your Skills
Time to find out what they've learned! The final lesson of a five-part series has learners complete a 39-question multiple choice review. They use what they've learned in the previous lessons to complete questions that include concepts...
Curated OER
Geometry Level 3
What a wonderful resource! Learners create two-dimensional shapes according to the instructions stated, use the squares to make a triangular prism, a cube, and a pyramid, and identify features of plane shapes, among a myriad of other...
Curated OER
Recognize and Draw Shapes
Each of these 10 shapes comes with a question for learners to answer as they analyze its attributes. They examine the following shapes: hexagon, trapezoid, pentagon, circle, diamond, parallelogram, rectangle, triangle,...

Volume of Composite Shapes
It's the parts that make the whole. Learners apply volume formulas to composite figures to find the total volume of the figure. Previous lessons in this series taught the methods for finding the volume and/or dimensions of...
Mathematics Vision Project
Module 5: Modeling with Geometry
Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...
