Bring about the change you want to see in the world  or at least in your lesson plans. Young mathematicians learn about translation and reflections by applying them to polygons on the coordinate plane. Results provide data to...

Comparing unit prices of food products is a skill that learners will use for the rest of their lives. Here is a simple plan that provides practice calculating the unit price for various grocery store products. Use two jars with differing...

Multiply your understanding of multiplying fractions. A short activity teaches pupils how to multiply fractions. By using fraction models, they get a better understanding of the concept.

Second graders listen to the story Miss Nelson is Missing by Harry Allard and James Marshall. In this literature lesson plan, 2nd graders predict the story's ending with drawings and discussions within groups.

Use your pupils' sense of curiosity to explore the Parallelogram Law. Here is an activity that outlines a complete lesson from beginning to end, allowing pupils to follow a conjecture through to the proof stage.

Kindergarteners practice basic addition and subtraction. For this math lesson, students sing a song about pigs on a farm to help them understand the concept of adding and subtracting things together. Some excellent extension activities...

Learners investigate ordered pairs. In this math lesson, students plot and locate ordered pairs in a coordinate plane and are exposed to how to read and create a map.

Students graph data of sea turtles hatching rates from Watamu/Malindi Marine National Park and Reserve in Kenya.  In this math lesson, students use real life science data to calculate mean and median values. Students use...

Here is a math instructional activity which has learners practice multiplying two and three digit numbers by one digit numbers. They discuss multiplication strategies and use those strategies to play a game.

Students calculate the square root of a given number using carpenter's square measurements. In this math lesson, students relate this method on the Pythagorean theorem. They answer practice problems after the exploration activity,

Find Pythagorean Triples like the ancient Babylonians. The resource presents the concept of Pythagorean Triples. It provides the system of equations the Babylonians used to calculate Pythagorean Triples more than 4,000 years ago. Pupils...

Two methods are always better than one! The eighth installment in this series asks pupils to convert decimals to fractions using two approaches. Individuals first use the more traditional approach of long division and then use reverse...

The 23rd segment in a series of 25 presents random samples from two populations to determine whether there is a difference. Groups determine whether they believe there is a difference between the two populations and later use an...

Putting a rectangular object into a circular one—didn't the astronauts on Apollo 13 have to do something like this? Learners first construct the center of a circle using perpendiculars. They then discover how to inscribe a rectangle in a...

First angle measures, now segment lengths. High schoolers first measure segments formed by secants that intersect interior to a circle, secants that intersect exterior to a circle, and a secant and a tangent that intersect exterior to a...
