The slope of the land is an important feature when considering the erosion that will occur. In this resource, which is part of a rain garden unit, learners calculate the slope of the proposed garden site. Even if you are not planning a...

What do magnetic fields look like? The best way to learn about magnetic fields is to try identifying them for yourself. Scholars will understand the importance of magnetic fields after completing this experiment. The extension activities...

Have your class design their own mathematical study aids. Learners collaborate in groups on the design of tri-fold presentation describing the relationships between mathematical computations. Then, they write a business letter to the...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to students their different roles in the activity, the teacher reads aloud a...

A page right out of the Holt Geometry book. Use a graphing calculator and graph paper to explore transformations with matrices.  

An activity around linear equations, slope, and intercept is here for you. In it, young mathematicians engage in a whole-class activity while the teacher uses the overhead projector graphing calculator. This activity also focuses on...

Students explore circles using a graphing calculator. In this circles lesson, students write the equation of a circle with a given center and radius length. Students find the most appropriate model for each combination of data they...

High schoolers practice using graphing calculators and spreadsheets as they explore numeric limits using sequences and functions. They complete a sequencing worksheet, and determine which sequence corresponds to story a story called...

Students calculate the surface area of prisms. For this geometry lesson, students investigate the properties of prisms and analyze ways to calculate the are of a rectangular prism. They derive the formula for surface area.

Learnersinvestigate three-dimensional shapes. In this geometry lesson, pupils calculate the volume of cylinders using the given dimensions. They create a formula base don observation before using the real formula.

Middle schoolers calculate gear ratio as they solve word problems. They discuss and find slopes as they relate to real life. Additionally, they hey use ratio and proportion to make predictions and solve problems.

Middle schoolers speculate on the better rate of pay: a dollar a day for 10 days, or a penny the first day, two pennies the second, doubling each day for 10 days. Start by listening to the story The King's Chessboard, by David Birch....

This is a nice hands-on activity where young geometers create trapezoids and calculate their area by looking at areas of quadrilaterals and triangles. 

Students collect temperatures using a probe and examine data.  In this temperature lesson students complete an activity using a graphing calculator.
