Great lesson plans covering a wide-range of math-related subjects.

There are a set of three lessons here that help students with the concepts of angles. Each of the lessons is a hands on approach to help students learn fundamentals angles and fundamental properties in geometry.

The students will be split into small, cooperative groups and build a city following specific guidelines. The students will learn how a city is constructed with angles, intersections, parallel, intersecting, and transversal streets. They...

NZMaths is a New Zealand teacher resource that provides lesson plans for students in algebra, geometry, measurement, numbers, statistics, logic and reasoning.

This fourth-grade geometry lesson teaches the definitions for a line, ray, angle, acute angle, right angle, and obtuse angle. We also study how the size of the angle is ONLY determined by how much it has "opened" as compared to the whole...

[Free Registration/Login Required] In this lesson, learners use the geometry program GeoGebra to explore Cavalieri's Principle, specifically to investigate whether it applies when calculating the volume of oblique solids. Lesson includes...

Calling all Shape Detectives! In this weeklong adventure, the children will explore and search for basic shapes as they go on a shape hunt. They will describe, match, sort and compose a variety of two-dimensional shapes, and create a...

The animals need help! In this week's Afterschool Adventure, children will take the role of Animal Assistants and use their spatial skills to help save the day. Each section of this weeklong adventure is introduced by a video clip or...

Sixth graders use substitution to find the values of equations and expressions they wrote using appropriate math symbols.

I love blending art and math. I want my students to develop a depth of knowledge for 2D plane shapes and distinguish polygon from non-polygon shapes.

In this task, students are shown three unit squares and two line segments connecting two pairs of vertices. They are asked to find the area of a triangle formed by intersecting lines. They can solve it using coordinate geometry or...

In this exploration, students will apply their knowledge of finding volume and surface area of cylinders and rectangular prisms. Students will make recommendations to the local movie theater after determining which package is cost...

This inquiry instructional activity explores the definitions of quadrilaterals and the properties of the diagonals of quadrilaterals to classify quadrilaterals. Students will work cooperatively to justify conclusions. This lesson plan...

In this activity, students will be required to generate a formula for volume of a rectangular prism. Students working in cooperative groups will use prior knowledge for finding area of a rectangle to determine the "amount of area in a...

This lesson allows students to discover the number Pi. By measuring real life objects, students will get to see where the number Pi comes from as well as how the circumference formula is derived.This lesson plan was created as a result...

Get your spy glasses ready! In this weeklong adventure, children will explore shapes and their attributes and use this knowledge to decode a secret message. Children will learn about two-dimensional (flat) and three-dimensional (solid)...

This lesson plan provides a cross-curricular lesson for second grade students. Teachers will read Elino R J. Pinczes' One Hundred Hungry Ants and then engage the students in hands-on division activities that connect to the book.

[Free Registration/Login Required] In this lesson plan, learners build geometric models of graduation caps using stiff paper. The activity requires the application of skills in finding surface area, understanding similarity, knowing the...

In this lesson, students will learn that math is important in navigation and engineering. Ancient land and sea navigators started with the most basic of navigation equations (Speed x Time = Distance). Today, navigational satellites use...

Use Cabri Jr to copy an angle. The activity is followed by a student-to-student interview/reflection sheet intended to require students to think, talk, and write about why the construction worked. The reflection sheet could be adapted...

Picture a roll of toilet paper; assume that the paper in the roll is very tightly rolled. Assuming that the paper in the roll is very thin, find a relationship between the thickness of the paper, the inner and outer radii of the roll,...
