Chalkboard Challenge: Fifth Grade Math Review
This PowerPoint addresses fifth grade math concepts, focusing mostly on geometry. The interactive math review game is in a "Jeopardy" style format and enables students to revisit the topics in geometry such as polygons, quadrilaterals...
Curated OER
Naming Shapes
Students study geometric shapes and practice naming them properly. In this geometry lesson, students work in groups to give definitions of the vocabulary to each other in their own words. Students also visit a lower grade and teach...
Curated OER
Midsegments of a Triangle
Students analyze midsegments of triangles in this lesson. They use Cabri Jr. software to observe the relationships between interior angles and midsegments of triangles. Specific instructions for creating this lesson in Cabri Jr. are...
Curated OER
Circle Theorem
In this geometry activity, students draw an illustration of a circle centered between two points. They draw three line segments. Students answer two questions about the resulting angles. A sample, interactive drawing is included with the...

Conditional Statements
In this geometry worksheet, students read given sentences and identify the hypothesis and the conclusion of the conditional statements. There are 21 questions.
Curated OER
Shapes Are Everywhere
Third graders use various shapes to identify polygons and understand symmetry. They explore pattern blocks noticing their similarities and differences, then share with other team members. They draw 3 polygons in their journals and...
Curated OER
Investigating Segments in a Right Triangle
High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...
Curated OER
Trajectory Perplexity
Students investigate measuring angles correctly through projectiles. In this geometry lesson, students launch a projectile to investigate the importance of how to measure an angle correctly and to explore trajectory. They collect...

Indirect Measurement
Students measure and apply their knowledge of proportion to solve problems. In this geometry lesson plan, students measure using a meter stick, small mirror and measuring tape. They compare and contrast their measurements to objects...
Curated OER
What Shape Am I?
First graders analyze characteristics of geometric shapes. They identify, describe, and create simple geometric figures. They analyze characteristics of geometric shapes and determine the defining attributes of a circle,...

SAT Problem Solving
In this geometry worksheet, 10th graders practice taking math questions that are on the SAT. The questions deal with a variety of different math. There are 10 questions with an answer key.
Curated OER
That's So Square
Students familiarize themselves with the three most common geometric shapes: circles, triangles and parallelograms. They sketch, sort, and name the shapes.

Introduction to Fractals: Geometric Fractals
Middle schoolers study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Middle schoolers complete worksheets based on...
Curated OER
How Tall Is It?
Students identify how tall a tree is. In this measurement instructional activity, students use "luminometers" to measure a tree and complete a data sheet.
Curated OER
Exploring Functions with CAS
Your mathematicians will examine several conjectures regarding even and odd functions and investigate a formal proof of the conjectures using CAS.
Curated OER
Geometry House!
Fourth graders use computer drawing tools to create a house of geometric shapes.
