While this lesson focuses on a study of the Hudson River, it could be used as a template for a discussion of map skills, converting measurements, and plotting a route. The lesson includes vocabulary and other resources to make it a...

What a great way to introduce life cycles in your classroom! Kindergartners learn about chickens using visual aids, vocabulary lists, and more. If possible, you can have your class watch the process up close and personal by bringing in...

Some of the most important vocabulary in the study of geometry is presented here. In this PowerPoint, learners view the definitions for points, lines, segments, and rays. The definitions and graphics are clear, and kids are also coached...

The subject and the predicate are two vocabulary words that every young writer must know. This short, but effective, presentation aptly describes what the subject and predicate are, what role they play in a sentence, and offers some...

Take your class on a hypothetical fishing trip! This word problem gives a data set describing how many fish each of the nine contestants in a fishing derby caught. The numbers range from zero to ten. Learners examine the data and answer...

Here is a worksheet to practice or review basic matrix operations of addition, subtraction, and scalar multiplication. First, define and discuss key vocabulary terms, then have individuals work five simple problems. There are detailed...

Does your bank pay you for allowing them to hold your money? The lesson covers three different ways your money can make money. Topics include certificates of deposit, statement savings accounts, and money market accounts.

Does your bank pay you for allowing them to hold your money? Class members investigate three different ways money can make more money. Topics include certificates of deposit, statement savings accounts, and money market accounts....

You say that perpendicular bisectors intersect at a point? I concur! Learners investigate points of concurrencies, specifically, circumcenters and incenters, by constructing perpendicular and angle bisectors of various triangles.

Young mathematicians are introduced to fractions in a unit that helps them to understand parts of a whole.

Turn your class upside down as they explore the reciprocal functions. Scholars use the unit circle to develop the definition of the secant and cosecant functions. They analyze the domain, range, and end behavior of each function.

Your future chefs will appreciate this comprehensive lesson where learners practice operations on fractions using pizza and soup analogies. Learners begin with a pizza analogy that requires the learners to multiply a whole...

Have you hit a wall when trying to create performance task questions? Several open-ended response questions require a deep level of thinking. Topics include triangle congruence, quadrilaterals, special segments, constructions, and...

Almost every teen wants a car, but can they really afford one? The lesson walks pupils through how to identify a budget, find all of the costs associated with car ownership, and determine if they should buy the car or keep looking.

Learn through constructions! Learners examine a translation using constructions and define the translation using a vector. Pupils then construct parallel lines to determine the location of a translated image and use the vector as a guide.

We can mathematically model the path of a robot. Learners use parametric equations to find the location of a robot at a given time. They compare the paths of multiple robots looking for parallel and perpendicular relationships and...

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...

Lead your high school class on a journey through the world of symmetry and reflections as you discuss geometric principles. Pupils differentiate between reflections and rotations, explore rotational symmetry, and investigate how to...

Is that drawn to scale? Capture the artistry of geometry using the ratio method to create dilations. Mathematicians use a center and ratio to create a scaled drawing. They then use a ruler and protractor to verify measurements. 

Can you follow a composition of transformations, or better yet construct them? Young mathematicians analyze the composition of dilations, examining both the scale factor and centers of dilations. They discover relationships for both...

It's time for your young artists to shine! Learners examine images to determine possible similarity transformations. They then provide a sequence of transformations that map one image to the next, or give an explanation why it is...

You can explain it, but can you do it? After learners view a sequence of transformations, the next logical step is creating the transformation. Challenge your classes to construct a composition of transformations and verify the...

Playing with mathematics can invoke curiosity and excitement. As pupils construct triangles with given criteria, they determine the necessary requirements to support similarity. After determining the criteria, they practice...

What is the relationship between a hemisphere, a cone, and a cylinder? Using Cavalieri's Principle, the class determines that the sum of the volume of a hemisphere and a cone with the same radius and height equals the volume of a...
