Are your geometry whizzes learning about angles and shapes? This online learning exercise gives 10 multiple choice questions based on images and word problems. Concepts include deducting angle degree, classifying shapes, and identifying...

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging students to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

What does translating points on a number line have to do with solving inequalities? Young mathematicians first learn about translations of points on a number line, and then use this information to solve linear inequalities in one variable.

Here is a simple and clever activity which illustrates the concept of mathematical proportion and size quite effectively. In it, two pupils hold baseball bats: one is a regulation-size bat, the other is a miniature souvenir bat. The...

In this telling time worksheet, students use fuses which burn at different times to tell times in 45 minute increments. They solve this number puzzle and check their answer with an online solution.

Young mathematicians identify different cases of intersecting secant lines. They then investigate the case where secant lines meet inside a circle.

Practice the metric system with this basic activity. Guided by a fun illustration of a mouse, students problem solve using a balance scale. Two graphic organizers allow them to record their findings in grams and kilograms.

This a fun problem for young geometers to play with while gaining important insight into deductive reasoning. Some will find the answers very quickly, others might take a less direct path, but all will use their knowledge of the sum of...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson plan series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Your learners will get a lot of practice finding volumes of pyramids and cones in this nicely written practice worksheet. It even has room for them to show their work. The first few pyramids and cones are labeled pictures, while the last...

Use a hands-on approach to exploring the concepts of related rates in your AP Calculus class. Individuals explore the effect of the rate of change on a variable related to a variable they control. After analyzing the data they...

Is 0.56 stronger than -0.78? Interpret the correlation coefficient as the strength and direction of a linear relationship between two variables. An algebra lesson introduces the correlation coefficient by estimating and then...

There isn't a more popular geometry formula than the Pythagorean Theorem! Learners understand the special side relationships in a right triangle. They use the Pythagorean Theorem to find missing sides and to solve problems. They begin...

Help learners understand that perimeter and circumference are one in the same. Learners apply their skills to determine the perimeter/circumference of triangles, rectangles, and circles. They then use the same strategy to find the...

The middle of the data is important, but what about the rest of it? The lesson plan shows learners the importance of the range, quartiles, and extreme values. Pupils practice finding each of these values from given data sets.

Explore linear functions! In this Algebra I lesson, mathematicians graph data in a scatter plot and use a graphing calculator to find a linear regression and/or a median-median line. They use the model to make predictions.

High schoolers use diagrams of the constellation Orion and the constellation Ursa Major which show the distances between the stars of the constellations. They calculate the perimeters of each, find the average distance of the stars for...

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.

In this geometry worksheet, 10th graders use the theorems regarding right triangles to find the missing length in a special right triangle. The one page worksheet contains eleven questions. Answers are included.
