Students use the slope and y-intercept to graph lines. In this algebra lesson, students graph linear equations and apply it to solving real life problems.

Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory lesson.

Students explore the relationship between geometry and ancient American art. They see how to recognize geometric properties in specific works and explain how these properties contribute to their meaning and artistic merit.

Students use logical arguments and inductive reasoning to make or disprove conjectures. After observing a teacher led demonstration, students discover that the deductive process narrows facts to a few possible conclusions. In groups,...

Students explore lines, rays, line segments, and planes. In this math lesson, students discuss the math concepts and direct their instructor in graphing functions. Students collaborate in graphing additional functions.

Explore the concept of creating and describing 2D and 3D shapes.  Using geometry your scholars will describe the attributes of shapes and their properties.  They explore and discover what happens when you combine shapes and...

Students identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.

Using a varity of strategies, young mathematicians solve multistep word problems. They play a logic game as a whole group, and then work with a partner on a computer to complete a worksheet that requires a variety of problem solving...

Students identify the different types of bridges. Using the internet, they research information on how they are built by completing a scavenger hunt. Locating a specific area, they determine which type of bridge would be appropriate and...

Students extend and create patterns. Through a variety of activities, they discover patterns as they exist in math and their everyday lives. Students create a necklace that represents a pattern.

Students explore the concept of tessellations. In this tessellations instructional activity, students use an applet to construct tessellations. Students use regular polygons to construct tessellations. Students find patterns and symmetry...

The class explores the concept of complex numbers on a website to generate their own Mandelbrot sets. They will practice performing operations with complex numbers and then to get a visual understanding, graph the absolute value of a...

Fourth graders use polygons to create animal figures with symmetry. In this polygons and symmetry lesson plan, 4th graders create a symmetrical animal collage by cutting and gluing geometric shapes and figures from math...

Make origami ducks with your class to reinforce geometry concepts and vocabulary; develop fine motor and visual translation skills; and enrich study of Japanese culture, the pond habitat, or migration. Create a whole group "worksheet"...

Students use ratios and proportions to represent quantitative relationships as they investigate the concept of how percentages are used by designers. Students decorate the same room using three different percentages of colors.

Students explore the concept of Pascal's Triangle. In this Pascal's Triangle lesson, students use an applet called 'Coloring Multiples' to explore Pascal's Triangle. Students develop patterns starting with various numbers in Pascal's...

Students discover the relationships of the lengths of the sides of right triangles and right triangles using a series of drawings on dot paper. They investigate and solve problems of standard (customary and metric units) and non-standard...

Here is a math instructional activity which has learners practice multiplying two and three digit numbers by one digit numbers. They discuss multiplication strategies and use those strategies to play a game.

Second graders examine the metric system. In this metric system lesson, 2nd graders compare measurements of common objects in metric units. Students compete in a garden scavenger hunt.

A fun (and delicious!) instructional activity teaches measurement to your third graders. They work in small groups to first predict, then to measure the weight, circumference, and number of seeds found in a watermelon. Everyone gets to...

Students make a box and whiskers plot using the TI-73 graphing calculator. Each student would have their own calculator but they would work in small groups of two or three to help each other enter the data and make the plots.

Students explore the concepts of length, perimeter, and area. In this math lesson plan, students use Shape Explorer to practice finding length, perimeter, and area.

Study geometry through the concept of quilt design. High schoolers examine the geometric shapes in various quilts and then create their own quilts using geometric shapes that fit together. In the end, they write a paragraph to...

Seventh graders use highest and lowest points of land elevation around the world to find the differences. Sea level is zero, so students be operating with positive and negative numbers. After students find the information on the...
