Creating Shapes
In this geometry skills lesson, students respond to 4 questions that require them to examine the pictured shapes and follow the instructions to create new shapes out of them.
Curated OER
Vectors
In this geometry worksheet, students investigate vectors. They add, subtract and identify the magnitude of each vector. There are 4 questions with an answer key.
Curated OER
Geo-Mat
Students review plane figures by playing a game that resembles "Twister." They listen to directions to locate a large example of the figure which is placed on the floor.
Curated OER
An Introduction to Quadrilaterals
Students explore different types of quadrilaterals. Students define the terminology used with quadrilaterals. They create particular quadrilaterals based on specific characteristics of the quadrilaterals using an online tool.
Curated OER
Perimeter and Area
Seventh graders develop strategies for finding the perimeter and area of large geometric figures. Through lecture and guided practice, 7th graders practice the strategy of dividing a geometric shape into smaller more manageable shapes...
Curated OER
Polygon Perimeters
Students define the terms polygon and perimeter to begin the lesson. Using a calculator, they practice determining the perimeter of various symbols in a painting. They discuss how geometry and art are related to one another.

Math 53 - Midterm 1 Review
In this math worksheet, students eliminate the parameter to find a Cartesian equation of the curve given by the parametric equations.
Curated OER
Missing Angle Problems
In this problem solving worksheet, 6th graders focus on the angles described in each word problem. Students must solve for each of the 6 problems, giving a written explanation for each in the space provided.
Curated OER
Polygon Perimeters
Students complete worksheets where they calculate the perimeter of polygons. In this perimeter of polygons lesson plan, students divide complex shapes into simple shapes to find the perimeter.
Curated OER
Flowchart Development
Students identify the parts of a flowchart. In this sequencing lesson, students define and then create their own flowcharts.
Curated OER
Parallel-o-Home
Students investigate the usage of parallel and perpendicular shapes in the real world. In this geometry lesson, students investigate shapes for properties that are related to the real world. They relate all the properties of shape tot he...

How Big Is It?
Fifth graders look at the Garrison flag and estimate how big it is. In this measurement lesson plan, 5th graders then calculate the area and perimeter of the flag.
Curated OER
Area of Quadrilaterals
In this math worksheet, students read an informative chart about how to find the area of quadrilaterals. Students then answer 6 questions in which the area of quadrilaterals is calculated.
Curated OER
Tangram Shapes
In this tangram worksheet, students trace the tangram pieces and cut them out to solve the five problems. Students make shapes with the tangram pieces.

Tango's Story
Fifth graders listen to "Grandfather Tang's Story" and use tangram pieces to create animals described by the main character.
Curated OER
The Chicken Run
Fourth graders work in a group of 4 to make rectangle with a 12m length of string. They discuss its perimeter and how they would calculate its area. Then another group of 4 make another rectangle and estimate if the area would be greater...
Curated OER
Fractions of a Set
Third graders use fractions to describe part of a set. In this fractions lesson, 3rd graders are introduced to fractions through a book and use pattern blocks to describe a fraction as a part of a set. This lesson includes a scripted...
