Here is a straightforward example of how to apply the Pythagorean Theorem to find an unknown side-length of a trapezoid. Commentary gives additional information on proving that the inside of the trapezoid is a rectangle, but is...

Let's use math to solve an argument. Jon and Charlie are debating about who can run farther, but who is right? That's what your class will figure out as they apply their understanding of fractions to this real-life situation. A simple,...

It is easy to find the area of a triangle where the base and the height are given. But in this resource, it is up to your geometers to identify the base and height of the triangle. In fact, your pupils will learn that there are three...

Challenge: create an assessment that features higher level thinking from beginning to end. A ready-made test assesses knowledge of dilations using performance tasks. Every question requires a developed written response. 

Put together the pieces and model a parabola. Learners work through several examples to develop an understanding of a parabola graphically and algebraically. 

Can they put it all together? Ninth graders apply what they know about proofs and triangle congruence to complete these proofs. These proofs go beyond the basic triangle congruence proofs and use various properties, theorems, and...

Show your school spirit! Class members use instruments or sing along and employ what they have learned in the two previous lessons to perform their school's songs.

Every bug is an insect, but not all insects are bugs. A presentation lists the characteristics of insects, describes their body parts, and explains metamorphosis. It also details every order and includes photographs and multiple facts...

Eleventh graders compile a list of places in the United States where they have either traveled or where their relatives or friends live. They collect travel posters, brochures, postcards, and maps from their region of the United States.

Beginning biologists learn the characteristics of the five classes in the arthropod phylum. A student handout lists characteristics to help them identify five specimens. You will need to collect an example of each: arachnida, crustacea,...

Clever! Earth science learners construct a model of a planet containing a magnetic core. The planet, Terrabagga, is made out of a paper grocery bag, magnets, a dead D battery, and rubber bands. Pictures of each step of the construction...

How accurate is data collected from a sample? Learners answer this question using a simulation to model data collected from a sample population. They analyze the data to understand the variability in the results.

A lesson involving mapping, the use of a compass, writing and following directions, and exploring the first two themes of geography is here for you. Learners create original maps that show the routes they take through their own...

Class groups collaborate to produce the storyboard for their video project. After determining the sequence of scenes, the camera angles, and characters in each scene, each group member is assigned a number of scenes to illustrate. When...

Fun from A to Z! Use a collection of alphabet worksheets to help kids practice their letters. Kids can color and trace each letter, and draw items from a word list to indicate each letter.

Rainy day schedule doesn't mean you can't stay fit! Use a collection of indoor physical activities during periods of inclement weather, substitute teaching days, or for those afternoons when your class just wants to move around!

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Determine whether two triangles are similar. The lesson presents opportunities for pupils to find the criterion needed to show that two triangles are similar. Scholars use the definition of similarity to find any missing side...

What type of quadrilateral is that? Discover the difference between the types of quadrilaterals. Small groups investigate types of quadrilaterals using geometry software to find their properties. To keep track of the different...

What do skateboarding and baked goods have in common with math? You can use them to connect half-pipe ramps and cakes to arcs and sectors. Pupils compare the lengths of three different ramp options of a skate park. They calculate the...

What are the musical elements that characterize a school's fight song or its alma mater? Class members listen to examples of fight songs and alma maters from various schools, play a listening game, and then create a list of the...

In this math instructional activity, learners learn to measure common classroom objects or body parts using a standard inches ruler and a centimeter ruler. Students measure 21 objects in both ways.

By now your class most likely has experience using a ruler, but they may not have learned to measure length to the quarter inch. This handout begins by explaining how, and then gives learners an opportunity to estimate these more...

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...
