Ninth graders investigate the concept of relations and interpret graphs and tables. They analyze given data and look for a pattern to determine if the numbers represent a function. Students practice solving scientific word problems that...

Second graders investigate the reasons animals hibernate. They measure their own heart rates and compare them to those of a hibernating bear. In their journals, 2nd graders record facts about and characteristics of hibernation and...

In this Dig Magazine archeology quiz, students answer 12 multiple choice questions complementing the November 2010 issue. Page contains answer and additional resources link.

In this beginning reading module, the instructor models how to pronounce words that incorporate "si", "su", "ci", "ti", or "tu" in them. Students are prompted to with the video segments at various times. Students can choose to sound out...

This session will examine how the TI-83+ can be used to improve instruction in Algebra II classes. We will look at different objectives from the Algebra II curriculum and examine several ways that calculators can improve student...

In this activity, students use the TI InterActive! to construct the expression of a polynomial curve based on its dynamic properties. They explore the behavior of the curve at certain points within its domain. Students also determine the...

This activity introduces students to Activity Center. In this activity, students will explore change in the context of cellular telephone charges. Students will create a scatter plot showing that the rate per minute for a "pay as you go"...

During this activity, students will explore the expected cost of college and also look at methods of saving money for the future. Comparing simple and compound interest will help students make decisions about their future. Students will...

In this Computer Algebra System (CAS) activity students use Riemann sums to estimate the distance traveled on a trip at various speeds. They utilize the concept of Riemann sums to calculate the area under a curve. Students find limits of...

Students can use these LearningCheck item banks to prepare for the Ohio AT exams.

In this activity, students can use a light sensor to record the light intensity at various distances from a bulb. They will compare the data to an inverse square and a power law model.

Based off of the hit television show NUMB3RS, this lesson shows students how using matrix multiplication can lead to solving real-world problems. In this situation, a painting is missing and the probability of travel betweek five cities...

Based off of the hit television show NUMB3RS, this lesson attempts to explain the betting system at horse tracks by having students vie for parcels of land on their calculators. Because the land boundaries are unknown until the finale of...

It is hard to imagine a way to mathematically describe a spiral. Spirals are commonly seen in nature. There are a number of different types of spirals. Some interesting examples include the spiral arrangements of scales in pine cones,...

Students compare the heating rates of wet sand and dry sand and study the effect of evaporation on heating rates. They create, interpret and analyze graphs of data. They also relate slope to rate of change.

In this activity, students plot a mathematical relationship that defines a spiral. They use technology to create a spiral and to plot a set of ordered pairs.

In this activity, students will measure round objects to determine the circumference and diameter, and use the data to explore geometric concepts of the circle with statistics.

Students use sample data to approximate models with the Transformation Graphing Application. They are introduced to the idea of discrete data sets being used with continuous function models. They also identify non-zero asymptote form of...

Did you learn to calculate using a 7-foot-long slide rule? Did you learn about the properties of numbers using brightly colored Cuisenaire rods? Ever wonder who invented the graph paper you used in geometry class? Go back to the...

Observe exponential decay with the classic M&M lab, here written up and ready to go. At the end, the author intends for students to send equations and data to the teacher via TI-Navigator, but this step can done on paper if the...

Sinusoidal data already obtained by swinging a can over a meter stick and measuring time and displacement from its resting position using a CBR or CBL with a motion detector. Using the TI-Navigator, you can monitor their "real time"...

Rainforests at the Crossroads: Examine the relationship between rainfall and runoff on Barro Colorado Island (BCI) over a period of one year. Then examine the data and use the TI-73 Explorer to graph and analyze the values.

Many aspects relating to the motion of a bouncing ball can be modelled mathematically. The first stage in modelling the motion is to collect some data. The Calculator Base Laboratory or CBR is a motion detector that can be connected to a...

Rainforests at the Crossroads: Use a Berlese Funnel to extract arthropods from leaf litter; count and sort the species of arthropods; and use a TI-73 Explorer to make a circle graph showing the different groups represented in their...
