How can you formally assess understanding of circle concepts? Pupils take a mid-module assessment containing five questions, each with multiple parts.

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...

Students convert angle measures between degrees and radians. They are given a copy of the task sheet with a graphic to help describe the situation. Pupils review the angle and arc relationship in a circle related to length of the...

In this geometry worksheet, 10th graders solve for missing sides and angles of a triangle. They use the pythagorean theorem to solve for the unknown in a right triangle. There are 5 questions on this worksheet.

In this geometry activity, 10th graders identify the missing angles using the polygons sum conjecture. They measure exterior and interior angles using their angle theorems. There are 63 problems.

In this isosceles triangle worksheet, students solve 19 multiple choice and short answer problems.  Students use the isosceles triangle theorem to determine unknown angle measures.

For this properties of quadrilaterals worksheet, students use the properties of quadrilaterals to find the perimeter, angle measurement or length of a missing side of a given polygon. Examples and explanations of the properties are...

In this similar figure worksheet, students use similar figures and indirect measurement to determine distance.  They use proportions of similar figures to determine scale figures.  This two-page worksheet contains 8...

In this law of sines worksheet, high schoolers solve 9 multiple choice and short answer problems.  Students use the law of sines to missing side lengths and angles of triangles.

Students measure the perimeter and area of their polygons. In this geometry lesson plan, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of...

In this geometry worksheet students explore similar polygons and determine measure of missing sides and angles. Students use indirect measurement with similar triangles and determine the area and volume of similar figures. The seven...

Seventh graders investigate how to make and set up a scatter plot. In this statistics lesson, 7th graders collect data and plot it. They analyze their data and discuss their results.

In this geometry activity, students solve problems based on the triangle inequality theorem(s) in which determine if the given lengths can form a triangle, given two sides of a triangle determine the range of the third side, and order...

In this solving quadrilateral word problems worksheet, students draw figures to identify quadrilaterals, use angles to find the ones missing, and explain classification. Students solve six problems.

Here is a great science lesson. It extends the concept of vision into the area of optical illusions, perspective, and tessellation. This well-designed plan has tons of great activities, utilizes interesting video, and should lead to a...

Geometry students use hinged mirrors to discover that the regular polygons are composed of triangles tessellating around a center point. They sketch triangles on paper models of the regular polygons having 3 to 10 sides and compute the...

Students sort and compare/contrast the lengths of various whales. They sort pictures of whales in order of smallest to largest, and given a rope marked with the lengths of the whales, they compare the actual lengths of the whales.

Middle and high schoolers solve and complete 29 various types of problems. First, they match each name with its correct formula. Then, students find the length of the missing side and the distance between the two points given. In...

Help your learners examine triangles. Pupils explore the different sizes and measurements of triangles. They discover triangles can be isosceles or scalene, and examine the attributes of triangles. Here is the website where you can...

Create trigonometric functions from circles. The first lesson of the module begins by finding coordinates along a circular path created by a Ferris Wheel. As the lessons progress, pupils graph trigonometric functions and relate them to...

Learners identify the stages of the water cycle. They listen to the book "Magic School Bus: Wet All Over," examine the Build Your Own Water Cycle website, predict and measure the amount of water in a jar for a week, and read a short play...

How can we identify shapes in the Universe? High schoolers will compare and contrast elliptic and hyperbolic geometry. They will also explore one possible way to measure the curvature of the Universe, namely, by measuring the sum of the...

Young geometers investigate two-dimensional figures using coordinate grids. They identify polygons and draw examples of their reflection, rotation, and translation on a coordinate grid. And they complete a worksheet practicing examples...

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...
