Twelfth graders apply the formula for finding the area of a triangle to various problems. They work real life problems for finding the area of a bathroom and the cost of tiling it. They play a game, Triangle Bingo, where they match...

A activity involving mapping, the use of a compass, writing and following directions, and exploring the first two themes of geography is here for you. Learners create original maps that show the routes they take through their own...

What does it take to build a stable arch? Pupils apply vectors and physics as they examine arched bridges and their structural integrity. They use vectors to represent the forces acting on the stone sections and make conclusions based on...

Students identify the relationship between chords, secants and circles. For this geometry lesson, students calculate the length of the chords. They sketch the secant lines on a circle.

Learners identify types of arcs and angles in a circle, find the measure of arcs and angles, and solve real world problems involving lengths of segments in circles, lengths, and areas.

For this geometry lesson, 10th graders break down a circle and identify the different parts. They discuss chords, diameter, radius, circumference, major and minor segment. There are 42 problems broken down into 5 different sections.

How many visual models can be used to show multiplication? Three basic kinds of models can be used to represent and explain the equation 4 x (9 + 2).  The commentary section provides description and graphics to explain the set...

The shortest distance between two points is a straight line. Learners use the Pythagorean Theorem to develop a formula to find that distance. They then find the midpoint using an average formula. 

Have learners graph complex numbers to gain a visual and mathematical understanding of the distance and the midpoint between two complex numbers. This lesson is short, but to the point, and addresses an important complex number...

In this math worksheet, young scholars graph the linear functions in comparison to the inequalities. Then they compare the line segments on the coordinate plane.

Students investigate the Pythagorean Theorem.  In this seventh through twelfth grade geometery instructional activity, students explore the Pythagorean Theorem and its converse and use it to find the length of the missing side...

Young scholars watch a segment of the PBS video which show the lemurs' ability to jump. In pairs, students collect measurement data involving each other's length of a standard step, a standing broad jump, and a long jump. They record...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

The key to understanding is making connections. Scholars explore angle dilations using properties of parallel lines. At completion, pupils prove that angles of a dilation preserve their original measure. 

Challenge scholars to prove the Pythagorean Theorem geometrically by using a cut-and-paste activity. They then must solve for the missing sides of right triangles.

In this geometry worksheet, 10th graders calculate the perimeter and area using the specific formula for that polygon. There are 5 questions with an answer key.

In this geometry worksheet, students calculate the midpoint and distance between two points. They use the correct formula to solve the area and perimeter of polygons. There are 20 multiple choice questions with an answer key.

Students identify the route of Magellan's voyage. In this map skills lesson, students use a globe to identify various coordinates where Magellan traveled.

Students find the perimeter and area of circles, triangles, and rectangles. In this perimeter and area lesson, the teacher gives students formulas for each shape and measurement and works through examples on the board. While no creative...

Challenge: create an assessment that features higher level thinking from beginning to end. A ready-made test assesses knowledge of dilations using performance tasks. Every question requires a developed written response. 

Sixth graders explore characteristics of two and three-dimensional figures. They observe the teacher demonstrate the faces, edges, vertices and names of specific figures. In groups, 6th graders examine and describe given figures. ...

In this geometry activity, students use a ruler and a protractor to measure the lengths of the line segments and size of the angles that make up a drawing of a Christmas tree.  The one page activity has one problem.  Answers...

Middle schoolers study the triangle inequality. They will identify, compare, and analyze attributes of two and three-dimensional shapes. Then they develop vocabulary to describe the attributes. They also use manipulatives to analyze the...

Students explore perimeter and area of regular and irregular polygons. They experiment with color squares and create different arrangements using the same number squares. Then they compare the area and perimeter measurements of each.
