This activity is designed to be used with small groups of children at a time. It can be used to help young children with basic number identification.

This activity is designed to give students the opportunity to estimate the least squares line given a set of points. The students are then able to check their "best fit" line by running a linear regression using the graphing calculator.

Students have trouble understanding the Central Limit Theorem (CLT). This activity is designed to show them what the theorem is saying. The students develop repeated lists of numbers from 1 to 10 and finding the mean of each list. : We...

This activity is designed to assess the comprehension of concepts related to periodic law.

This activity is designed to check student understanding of the chemistry of pigments and introduce spectroscopy using a relevant natural event.

This assessment is designed to assess the student's comprehension of a basic function for eukaryotic cells.

This activity is designed to motivate and challenge first year algebra students through a fun introduction to advanced mathematical concepts. It also offers extensions for upper grade level students. Students will recognize relationships...

This activity is designed for students to make conjectures about triangles. Students will create three lists to represent the measures of the angles of the triangle. The entire class list will then be sent to each student for analysis,...

This activity is designed to assess the comprehension of concepts related to the planets and other astronomical bodies in the Solar System.

This activity is designed for students who have already learned the definition of the derivative and that it can be used to determine the slope of a curve. (Continued. See "before the activity.")

This activity is designed to assess the comprehension of concepts related to solving equations, literal equations, and right triangle trigonometry.

Based off of the hit television show NUMB3RS, this lesson is designed to draw a connection between polar and parametric equations, as well as to expose students to the Trawler Problem (involving a fast boat chasing a slower boat which...

This activity is designed to help students work with linear regression models, error, correlation coefficients and coefficients of determination. In this activity students not only deal with the mathematical concepts of regression but...

This activity is designed to reinforce the concepts of reflections and translations by having the students create a virtual puppet using Cabri Jr. As they construct their puppets, students will reinforce their understanding of...

This activity is designed as an introduction to using the Carbri Jr. application on the TI-83+/84+ calculators. Students are guided through the menu system and are shown how to draw triangles, quadrilaterals and and a pentagon. Perimeter...

This lesson is designed to have students use linear programming to relate mathematics to the business world. Students calculate profits for a furniture business to prepare for the famous, semi-annual "Furniture Market" in North Carolina.

This activity is designed for students to use real-time data to generate a family of parabolic graphs. The data set will be generated by graphing the heights of a ball bounce with respect to time. Students will determine the regression...

This activity is designed to check student understanding of chemical relationships and light in preparation for a concentration lab.

Students will design swimming pools in the shape of polygons on grid paper with two vertices given.

This activity is designed to show students how to use a graphing calculator to find a limit by graphing, investigating a table, and by using the calc menu. (Continued. See "before the activity.")

This Arizona State article suggests that the omnitonic horn and valved horns were invented in the same era and for the same reasons. However, further reading points out the differences between the two. The explanation for their invention...

Here's a list of multiple choice questions to use to review different sampling techniques and types of studies. While this is intended to be an activity that utilizes TI-Explorer by having students send their answers to each other, it...

This page explains in fairly simple terms the basics of telescopes. It includes information on the various types of telescopes and the factors people use to select the correct telescope for them. Meade is a leading telescope manufacturer.

A sling psychrometer is used to measure humidity levels. Read about its history, how it works, its design, and how to use it. Includes a relative humidity table.
