Students make a simple sundial to examine the changes in shadows over time. In this sundial and shadow lesson, students make a simple sundial out of a manila folder and pencil. They observe how shadows change over time, and relate it to...

Combine algebraic and geometric strategies to find solutions. The task asks learners to find the coordinates of a third vertex of a triangle to create a triangle with a specific area. The project is a set of seven problems that...

Where do the coordinates lead? As children brainstorm ways to find the location of different buildings, they learn about coordinate points and how to use them to locate areas on a grid or map. They practice using ordered pairs by playing...

For this geometry worksheet, 10th graders determine that if two planes are perpendicular to the same line, then they are parallel.  The one page worksheet contains one problem with the solution. 

Learners explore the concept of solving systems of equations with two equations and two unknowns. In this solving systems of equations lesson, they work through problems of solving systems by substitution, elimination, and graphing....

In this geometry review game worksheet, students use the provided game cards and calling cards to play a Bingo-like game. Students learn geometric terms while playing a group game.

Students study West Virginia quilts. For this mathematics lesson, students use symmetry, geometric shapes, and patterns to create their own quilt square.

Third graders describe and compare attributes of two-dimensional shapes. They explain geometric terms, angles and shapes. Students demonstrate each vocabulary word with their body and they mirror the body positions associated with each...

Learners investigate the side splitter theorem. In this geometry lesson, students estimate and solve problems dealing with ratios and proportions. They identify angles created by lines that are parallel.

Third graders measure time and length. Through the use of video and technology, they explore key elements of measurement, such as units and conversion between units. They explore alternate units of measurement and apply measurement to...

What did you do over your summer vacation. Young wage earners must compare summer job options, and determine when each job earn the same amount and what that amount be. This be done by creating, graphing, and solving systems of...

In this geometry activity, students solve problems that are bimodal. They define properties of circles and triangles. There are 117 questions.

In this math activity, students complete the practice exam that asks for the solution to the parametric equation. Also they name the perpendicular line in relation to it.

In this geometry worksheet, 10th graders determine the answer to a vocabulary questions and then follow the give rules to place the answer in the appropriate place on the crossword grid.   The one page worksheet contains 18...

In this math worksheet, 6th graders complete multiple choice questions about number sentences, composite numbers, angles, and more. Students complete 30 questions.

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

Review context clues with your young readers using this helpful resource. Eight questions contain a missing word that pupils choose out of five options. The sentences provide ample context clues, making the choice more about test-taking...

In this geometry worksheet, students create a map that uses various geometrical concepts. The final project is the creation of a "geometrical town." Rubric for grading is included.

In this rounding learning exercise, students solve 40 problems in which whole numbers are rounded to the nearest 10. 100 or 1000. Students also round to the nearest dollar.

This study guide on lines and angles covers key terminology; line notation; parallel, perpendicular, and skew lines; and postulates and theorems about lines. It is available for download with free registration.

Learn all about lines. This lesson targets what is a line and the different types. Check-out the interactive simulations to know more about the lesson and try your hand at solving a few interesting practice questions at the end of the page.
