Teach your mathematicians how to identify different polygons based on their diagonals. Relating quadrilaterals to the different number of diagonals formed, high schoolers use the TI to create a visual of their shape.

Teach how to differentiate between chords and perpendicular bisectors. In this geometry instructional activity, high schoolers relate the properties of chords and circle to solving right triangle. They define what makes two chords...

Young mathematicians calculate the area of polygons in this algebra lesson. They find the determinant as they calculate the areas for triangles and quadrilaterals. They also use scalar multiplication to find the determinant.

High schoolers investigate different types of correlation in this statistics lesson. They identify positive, negative and no correlation as it relates to their data. They then find the line of best fit for the plotted data.

Students distinguish between kinetic and potential energy. They recognize that energy can change from one form to other forms. They identify and describe several forms of energy.

Students solve systems of inequalities. In this lesson, they identify the solution of the two lines and shade the solution. They identify the boundary line and the region representing the solution.

In this solving quadratic equations worksheet, 9th graders solve and complete 9 different types of problems. First, they graph each quadratic equation by factoring. Then, students find the axis of symmetry and the vertex. They also find...

Time to rock out! Discover the "life" cycle of the average rock using an illustrative stations lab and stimulating pairs game. Roll the dice to determine your fate: will it be melting in magma or chilling out to form igneous rock? The...

Young chemists have unknown compounds they need to sort. Performing three different tests on each, the chemical behaviors they observe become the basis for data analysis. 

In this clouds instructional activity, middle schoolers answer ten multiple choice questions about the types of clouds, the characteristics of clouds and the meaning of the prefixes found in the names of clouds.

The plot thickens to get a functional understanding. After a short review of plotting points on the coordinate plane, class members learn the difference between functions and relations in the second instructional activity in a...

Starting with similar triangles and dilation factors, this unit quickly and thoroughly progresses into the world of right triangle features and trigonometric relationships. Presented in easy-to-attack modules with copious application...

Let's eat kids. Let's eat, kids. Commas make a difference! Conventions 101: A Functional Approach to Teaching (and Assessing!) Grammar and Punctuation explains ways to teach the importance and use of conventions. Learners take part in...

Predict the year that college costs will double in your state using linear modeling. The first part of this two-part project based learning activity asks young mathematicians to use data from the College Board. They graph the data,...

Will learners pass this quiz by the skin of their teeth? Or will they know for sure that the teeth do not have skin? Ten questions require takers to list the functions of the mouth and teeth, name types of teeth and describe their roles,...

There are an infinite number of reasons to use the resource. Scholars drag vertical and horizontal lines to the graph of a rational function to identify all asymptotes. They investigate the connection between asymptotes and limits to...

Florida's Everglades come alive for young environmental scientists as they watch a video taken in the park and read a poem about the watery paradise. After a careful study of the two resources, class members consider the function of the...

Learners investigate properties of similar figures. In this properties of similar figures lesson, pupils construct similar figures using Cabri Jr. They dilate their figure to create a similar one, and discuss the relationships between...

Provide a Hooke for a lesson on elasticity with an activity that has groups investigate a set of springs. They use a set procedure to collect data to calculate the spring constant for each spring using Hooke's Law. The groups...

As part of an investigation of the folk traditions of their area, class members research the articles of clothing worn at earlier times, the fibers and materials, and the machinery used to produce these items. In addition, class...
