These floors were made for learning. Pupils use coordinate planes drawn on the classroom floor using tape to investigate parallelograms. They measure lengths, angles, and slopes to identify properties of parallelograms.

Leave all your travels needs to the math department. Pupils apply knowledge of triangles to identify a triangular path for a traveler to take. They use a given distance for the second leg of the trip and a constraint on the length of the...

Take the class over the rainbow. Pairs or small groups follow directions to create a spectrograph. The pupils measure the angles formed by the different colors of the spectrum along with calculating the lengths formed by the spectrum and...

Determine how far the ball rolled. The class watches a video of a person controlling a sphere rolling on the floor. Pupils develop some questions about the video and make estimates to the solutions of the questions. The teacher provides...

View a tree designed by Pythagoras. Pupils watch a video as a tree is built by using squares representing the side lengths of a right triangle, with each side of the squares becoming the side of another triangle. Learners come up with...

A unit plan that is over 50 pages in length offers lessons and activities that define stress, practice breathing techniques, bring awareness to triggers, refocus worries and fears, and offer practical problem-solving strategies. The unit...

Hit the highlights. Pupils complete 20 problems to review key aspects of skills learned about polynomials. They multiply, divide, and factor polynomials along with determining the zeros of a polynomial. At the end, individuals complete...

It is all about where the side is located. Pupils use their knowledge of angles in standard position to find reference angles. They use the Pythagorean Theorem to find lengths along a terminal side of an angle to determine the exact...

Add a little algebra to the geometry. Class members learn about the Addition Postulate for segments and angles. The pupils use their knowledge of solving equations to find lengths of segments and measures of angles. Individuals apply...

Apply perspective to similarity. Individuals learn about the Side Splitter Theorem by looking at perspective drawings. Pupils use the theorem and its corollary to find missing lengths in figures. Next, they practice using the theorem and...

Make sure it is all right in class. Pupils review the Pythagorean Theorem and find sides of right triangles, either by simplifying radicals or using calculators to find approximate lengths. Learners find out how to use the converse to...

Put trigonometric ratios into inverse. Scholars learn how to find an unknown angle in a right triangle by using inverse trigonometric ratios. The pupils understand how the inverses undo a trigonometric ratio to provide the angle measure....

Take ratios of sides to a new level. Pupils learn the definitions of the three basic trigonometric ratios in right triangles. Using the definitions, scholars find missing lengths in right triangles, based on a known angle. Individuals...

There are plenty of fish in the sea, but only a few good resources on regression. Young mathematicians first perform a linear regression analysis on provided weight and length data for fish. After determining that a linear model is not...

Name that statistic! Classmates each write their name and the number of letters in it on a sticky note to place on the board. As a class, they determine the median, mode, and range of the name lengths, and create a dot plot of the data....

Touch a circle once. Individuals watch a video and learn two theorems related to tangents and circles. The pupils then apply the theorems to find missing angle measures and lengths in figures. At the end, they practice their skills on...

Examine the concept of variation through observation and measurement. Middle schoolers will study a peanut and record any distinguishing characteristics visible as well as sketch their peanuts and describe them in writing. Their peanut...

What is the best way to prepare for an AP® exam? Learners become familiar with the AP® Biology exam by completing a full-length practice exam. The AP® test prep by the College Board contains multiple choice, grid-in, and free-response...

Now you can introduce rational functions using ... spaghetti. Scholars begin to learn about rational functions. After collecting data using an experiment on the amount of mass that different lengths of spaghetti can support, they write...

In many places in the world, people go to great lengths to get books to read. This beginning-of-the-year activity uses pictures of people reading in extraordinary situations to stimulate effective listening and speaking using the...

Can you prove it? Lead your class through the development of the Side Splitter Theorem through proofs. Individuals connect the ratio and parallel method of dilation through an exploration of two proofs. After completing the proofs,...

Young mathematicians examine area of different figures with the same cross-sectional lengths and work up to volumes of 3D figures with the same cross-sectional areas. The instruction and the exercises stress that the two...

Doing is more effective than watching. Learners use spaghetti to discover the relationship between the unit circle and the graph of the sine and cosine functions. As they measure lengths on the unit circle and transfer them to a...
