Students explore quilting. In this math patterns lesson plan, students define the perimeter of a quilt border, create tessellations using geometric shapes, and detemine the area of a quilt.

High schoolers explore the concept of fractals. In this fractals activity, students discuss Sierpinski's Triangle using an applet. High schoolers discuss the patterns involved with fractals. Students discuss the area of Sierpinski's...

Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.

Students play a game with mats of different shapes and colors spread out over a playing area. As a shape and color is called out students run the the corresponding mat and stand on it.

In this geometry worksheet, students are given a rectangle and a square. They verify ratios when given equal perimeters or areas. Students are given adjacent squares. They find the distance between the centers, and identify the means...

Students solve problems involving triangles. In this geometry lesson, students apply properties of triangles to find the missing angles and sides. They identify angles of parallel lines cut by a transversal.

In this maximum and minimum worksheet, students solve and complete 10 various types of word problems. First, they find the numbers if the product of the square of one of the numbers with the cube of the other number is to be a maximum....

Fifth graders use Geoboards to demonstrate how shapes can be made by looping the rubber bands over the nails. They make a triangle on their Geoboards. At least one side of the triangle should be either horizontal or vertical. The picture...

In this function worksheet, students find the slope of a line tangent to a given graph, they derive formulas for the area and perimeter of a given right triangle, they graph functions, and compute the derivative of functions. This...

Eighth graders investigate the Pythagorean Theorem and practice applying the theorem to various triangles. Finally, in the next lesson in the sequence, 8th graders create a song or a story to help them remember the Pythagorean Theorem.

Pupils explore similarity to see that the area of a circle should be a constant times the square of its radius. Students create a hexagon. Pupils share their designs with the class.

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...

Sixth graders derive an original formula for calculating the area of an irregular figure.

Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...

There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

Having a good working knowledge of math vocabulary is so important for learners as they progress through different levels of mathematical learning. Here is 125 pages worth of wonderfully constructed vocabulary and concept review cards....

You literally need to use the resource. Young mathematicians solve geometric problems by using literal equations. They go on to solve distance/rate/time problems by using literal equations — a great progression that helps introduce the...

Use of the resource = Opportunities for increased learning. Learners must use equations and inequalities to solve real-world and geometric problems.

Tired of going around and around for a resource on circles? Scholars determine the general equation of a circle on a coordinate plane, then participate in an activity matching equations to the radii and centers of the circles...

In this geometry learning exercise, students create circle, line and bar graphs using different comparisons of events. There are 24 questions with an answer key.

Dominoes, polyominoes, tetrominoes, and pentominoes are the subject of this interesting math activity designed for middle schoolers. Pupils cut out shapes that are embedded in a worksheet in the plan, and experiment with them by...

Lesson 16 in the series of 28 is a mid-module assessment. Learners simplify expressions, write and solve equations, and write and solve inequalities. Most questions begin as word problems adding a critical thinking component to the...

Shapes are so fun! Little ones explore, identify, and create shapes using tangrams or pattern blocks. The activity is intended to stimulate critical thinking while engaging learners through play and shape identification. Each child will...
