Add Them Up
Students explore the total voltage provided by several batteries in a series to a battery-operated device. They graph scatter plots, understand multiplication as repeated addition, and use a pattern to develop a formula. They learn how to develop a formula from a pattern of increasing voltage and...https://education.ti.com/en/activity/detail/add-them-up
Linearity and Density
Students will perform an activity to determine the density of a metal from a graph of mass versus volumehttps://education.ti.com/en/activity/detail/linearity-and-density
What is Boiling?
We will investigate the effects of heat on matter by studying boiling waterhttps://education.ti.com/en/activity/detail/what-is-boiling
Patterns in Percent
Students will use the % key to collect data about percentages of a given number. They will organize the data and look for patterns in percents. (For example, 10% of 20 is twice as much as 5% of 20.)https://education.ti.com/en/activity/detail/patterns-in-percent
Forensics Case 10 - Dropped at the Scene: Blood spatter analysis

They find the curve that best fits the ...https://education.ti.com/en/activity/detail/forensics-case-10brdropped-at-the-scene-blood-spatter-analysis
Circular Motion
In UCM, the net force called Fc is equal to mv2/r and is directed toward the center. This is demonstrated by an object that is suspended by a string and is moving in a circular path which makes a conical pendulum. In this experiment, you will measure the tension and the length of the string to ...https://education.ti.com/en/activity/detail/circular-motion_1
a-MAZE-ing Secret Paths
Students learn to add and subtract numbers using the calculator. They investigate patterns in place value and explore relationships between numbers on the hundred chart.https://education.ti.com/en/activity/detail/amazeing-secret-paths
Hat Trick
Students learn to solve a real-world problem in economics. Students get to understand how surveys often use a sample of people rather than all of the people involved. They also learn how to make decisions based on the results of a sample survey.https://education.ti.com/en/activity/detail/hat-trick
Mean As a Fair Share
This lesson introduces students to mean as a way to describe the center of a set of data. Often called the average, the mean can also be visualized as “leveling out” the data in the sense of “fair share”.https://education.ti.com/en/activity/detail/mean-as-a-fair-share-bc
Fractions and Skittles
Students will predict how many of each color will be in one pack of skittles before they open the package. Once they open the package, they will determine how close their predictioins are to the actual amount. Students then will come up with ratios and averages.https://education.ti.com/en/activity/detail/fractions-and-skittles
So Many Zeros!
Students will explore standard and scientific notation representations of numbers. Students will also discuss the need for different representations of very large or small numbers, and they will see real-world examples of these representations.https://education.ti.com/en/activity/detail/so-many-zeros
Golden Rectangles
Students measure rectangles and calculate ratio between the sides. They compare the ratio to the Golden Ratio (1.618).https://education.ti.com/en/activity/detail/golden-rectangles
