Compose and decompose sets of 13 and 14 and compare sets of each with your little learners. They use objects to construct sets of 13 and 14, record their answers, and compare sets in several different ways.

High schoolers are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Students investigate the properties of inclined planes and how implementing them can reduce the force necessary to lift objects off the ground. In this inclined planes lesson, students are introduced to the concept of simple tools and...

Tenth graders draw, label, plot and locate points on a coordinate plane. For this geometry lesson, 10th graders define a coordinate plane and identify the different quadrants. They relate coordinate plane to the game of battleship as...

Practice reading coordinate planes with a series of graphing worksheets. Kids read questions about symbols and shapes on specific coordinates, then use the answer section to indicate which shape in on the desired coordinates.

Identifying the location of ordered pairs on coordinate planes is the focus in the math lesson presented here. In it, 4th graders are introduced to coordinate pairs, the x/y axis, and the techniques associated with this type of graphing....

Turn a lesson on the coordinate plane into a class game of battleship with this fun math resource. Providing two coordinate grids and and places to fill in the ordered pairs that are guessed, this activity is a great way...

Teamwork and critical thinking combine to for a creative lesson plan on reducing greenhouse gas emissions. Ebullient environmental studies learners play a game in which they strategize how to place colorful energy wedges together to...

Although graphing a linear inequality on the plane is but a few steps added onto the graphing of a linear equation, for many learners the logical leap is quite intimidating. This approachable PowerPoint presentation breaks graphing...

Make your work as a teacher a little easier with a physical science project on simple machines. After introducing young scientists to these devices and identifying their different uses around the school, this project engages...

Five questions make up an interactive that challenges mathematicians to compare unit rates. Word problems question scholars about two friends going on a road trip. Scholars manipulate two cars on a coordinate plane to help solve word...

What's the best way to use a simple machine to solve a real-world problem? Scholars construct their own simple and complex machines to explore the concepts of work and force. They discuss examples of simple machines they have found in...

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

In this mathematics worksheet, 1st graders identify which object in an illustration has a flat side the same shape as the box shown. Then they look at other shapes and identify the ones with a flat side, if any.

Take some time to reflect on graphing. Learners count a point's distance from the line of reflection to create reflections of geometric figures. Given the rules for four basic lines of reflections, pupils determine the points to create...

A short video shows how to find the shortest distance between a line and a point on the coordinate plane. Using the fact the shortest distance is the perpendicular, the presenter shows the class how to find the intersection of the two...

One of the hardest skills for many young geometers to grasp is to move beyond just declaring obvious things true, and really returning to fundamental principles for proof. This brief exercise stretches those proving muscles as the...

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

Context is the key to understanding slope. A real-world application of slope uses a weight loss scenario with a constant rate of change to introduce the concept of slope of a line, before it makes a connection to the ordered pairs...

Using a teacher-built wind tunnel constructed from a paper concrete tube form, a fan, and a balance, individuals determine the amount of drag their rocket design will experience in flight. Pupils make modifications to increase the...

The documentary, The Legendary King of San Miguel Island, introduces the fascinating tale of Herb Lester, his family, and their life on San Miguel Island. Viewers have an opportunity to expand their study of the island and of...

Young theatre artists engage in a scavenger hunt to acquaint themselves with set design. The challenge is to search the site and match a separate maquette with each of the 24 clues.
