This lesson introduces students to Activity Center and is intended to help students understand the meaning of slope and y-intercept. They will explore the relationships between symbolic expressions and graphs of lines by using Activity...

Based off of the hit television show NUMB3RS, this lesson has students determine center of mass for a series of objects (approximate JENGA blocks), and then to push each level so that it "hangs over" the level below it. Following this,...

In this activity, students explore the operations of addition and subtraction. They use estimation, a place value chart, and a calculator to place seven randomly generated numbers in the ones and tens position in a place-value chart to...

This online exploration provides an opportunity to identify the different properties of waves and the relationship that exists between energy, wavelength, and frequency. Correlate images from the Hubble Telescope to the wavelength,...

In this activity, students learn to identify geometric series. They determine if a sequence converges and also learn to calculate the sum of numbers in a geometric series.

This activity center is used to illustrate the difference between the slant height and the actual perpendicular height (of the given square pyramid) by the use of the distance formula.

Lesson explore sensors focusing on ones that measure humidity. Students work in teams to design, build, test, and evaluate a hygrometer which was made out of everyday materials to measure humidity levels.
