It doesn't get simpler than this. Scholars first learn to simplify radicals by determining the prime factors of the radicand. The lesson progresses to simplifying radicals involving algebraic expressions in the radicand.

Discover how algebra tiles can help in dividing polynomials. Pupils watch as instructors demonstrate how to use algebra tiles to solve problems involving the division of a quadratic expression by a linear expression. Once they get the...

Show your math class how to use vectors in adding complex numbers. Vectors represent complex numbers as opposed to points in the coordinate plane. The class uses the geometric representation to add and subtract complex numbers and...

Students identify important properties of triangles. In this geometry lesson, students differentiate between medians, bisectors and altitudes in a triangle. They identify the properties of these important segments.

Young cartographers in groups hide treasure at school and then create a map to find it using pattern blocks and tiles. They make paintings with clues to create a visual representation of the location of their treasure. Groups present...

The Function That Shall Not Be Named? The eighth installment of a 35-part module uses a WhatPower function to introduce scholars to the concept of a logarithmic function without actually naming the function. Once pupils are...

Kids gain a deeper understanding of mathematical symbols, by playing an interactive game using flash cards. They complete an attached Missing Symbols Worksheet, flash card and an assessment are also included.

Student observe the effect soap (or detergent) has on the movement of food color in milk. Pupils observe the properties of solids and liquids while making butter. They read a poem, Shaking, and listen for ryhming words. Studdents...

Time for pupils to use their imagination! Learners examine the relationship between a system with no real solution and its graph. They then verify their discoveries with algebra. 

Students design their own playground equipment. In this design lesson, students take pictures of equipment they like and make a class pictograph of their favorite ones. They investigate the design, research equipment around the world,...

Using a TI Navigator to drag quadrilaterals around to create different shapes, students learn how to draw midpoints in their quadrilaterals. In this geometry activity, students solve problems using the properties of...

Introduce starting space scientists to the electromagnetic spectrum, expecially the portion of visible light. Teach them about wavelength and frequesncy. Then give them a roll of adding machine tape and a manila folder to make a...

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Students measure angles using a plane table kit. In this geometry lesson, students use trigonometric identities to find the values of the length of a football field.

You and your calculus learners will appreciate this description, discussion, and examples of the Intermediate Value Theorem. Applications of the theorem are also discussed.

Noah didn't construct this kind of arc. High school scholars first explore how angles can be formed in circles. They then learn relationships between angles and arcs by conducting an exploratory activity where they position and draw arcs...

Learners analyze data using bar graphs and the TI in this statistics lesson plan. They investigate quick polls and graph the data using different properties of statistics. This assignment requires a TI Navigator.

Examine the science behind computer communication. After defining the properties of magnets, learners simulate how a computer hard drive works by sending each other binary codes using the magnets. They use these communications to...

Students use models and symbols to represent properties of the Pythagorean Theorem. In this right triangle instructional activity, students connect real jobs to properties of right triangles. They solve word problems applying the correct...

As part of a study of percent and percent change, learners first complete an assessment task with several percent change problems. They then complete an activity using cards to create a diagram expressing percent increases and...

Time to learn about sundials. Scholars see how to build sundials after learning about Earth's rotation and its relation to time. The unit describes several different types of possible sundials, so choose the one that fits your needs — or...

Right triangles are so special! Use special right triangles to discover the trigonometric ratios. Pairs construct special right triangles and find the values of the ratios of the sides. In the process, they discover the ratios stay the...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Investigate vectors and learn how to use them. Explore why size and direction, as well as knowing speed and distance, are important components of the vector problems you are trying to solve. This is an extensive lesson which includes six...
