Inscribed Angles
Students use animation to discover that the measure of an inscribed angle is half the measure of its intercepted arc, that two angles that intercept the same, or congruent, arcs are congruent, and that an angle inscribed in a semi-circle is a right angle. They then discover that the opposite angl...https://education.ti.com/en/activity/detail/inscribed-angles_1
Interior Angles of Polygons

Explore the relationship between intersecting lines and the measures of various segments on those lines.https://education.ti.com/en/activity/detail/intersecting-lines-and-segment-measures
Pi and Precision
Students will collect the measurements of circumference and diameter for four objects in their group. (Cup, Can, Mint Candy, and a Coin) They will then investigate the accuracy of their data colletion using a numerical table and a scatter plot. Students must observe how closely their measurements...https://education.ti.com/en/activity/detail/pi-and-precision
You Are What You Eat
This activity involves data analysis of the number of fat grams versus calories in fast food hamburgers.https://education.ti.com/en/activity/detail/you-are-what-you-eat_1
Similarity with Shadows

We've Got You Covered: 2D Area
This lesson involves using the geometry tools to measure the area of two-dimensional shapes from the faces of three-dimensional objects they see in pictures taken outside of the classroom.https://education.ti.com/en/activity/detail/weve-got-you-covered-2d-area
What's Right about Triangles
This lesson involves examining a visual proof of the Pythagorean Theorem and supporting what happens geometrically.https://education.ti.com/en/activity/detail/whats-right-about-triangles
Solving Percent Problems
This lesson involves solving word problems dealing with percents by using visual and numerical representations of percents.https://education.ti.com/en/activity/detail/solving-percent-problems
One and One Equals Win
This lesson involves using proportionality and a basic understanding of probability to make and test conjectures about the results of experiments and simulations.https://education.ti.com/en/activity/detail/one-and-one-equals-win
The Pentagon Problem
This activity provides a simple, virtual "geoboard" that allows students to manipulate the polygon displayed on a unit grid. The grid squares provide a visual means of finding area.https://education.ti.com/en/activity/detail/the-pentagon-problem
Addition and Subtraction of Rational Numbers: Part 1
This lesson involves using pattern blocks to model addition and subtraction of positive mixed numbers for randomly generated numeric expressions.https://education.ti.com/en/activity/detail/addition-and-subtraction-of-rational-numbers-part-1
SD: How Far is Typical?
This lesson involves gaining a basic understanding of what standard deviation is measuring by examining the location of data around the mean.https://education.ti.com/en/activity/detail/sd--how-far-is-typical
Stratified Sampling
This lesson involves determining which of three different sampling methods - a simple random selection design and two stratified selection designs - would be most beneficial in selecting a survey sample within a given context.https://education.ti.com/en/activity/detail/stratified-sampling
Exponent Rules
This activity allows students to work independently to discover rules for working with exponents, such as the Power of a Power rule. Students also investigate the value of a power whose exponent is zero or negative. As an optional extension, students investigate the value of a power whose exponen...https://education.ti.com/en/activity/detail/exponent-rules
Riemann Rectangle Errors
Use three Riemann sums used to estimate the area of a plane region.https://education.ti.com/en/activity/detail/riemann-rectangle-errors
Center of Mass
Students will identify and interpret the mean geometrically as the location of the coins on the ruler such that the sum of the distances on either side of the mean is the same.https://education.ti.com/en/activity/detail/center-of-mass
Center and Spread
Students will recognize that the mean and standard deviation (SD) and the median and interquartile range (IQR) are two ways to measure center and spread.https://education.ti.com/en/activity/detail/center-and-spread
Confidence Levels for Means
Students will interpret a confidence level as the average success rate of the process used to produce an interval intended to contain the true mean of the population. Students will recognize that as the confidence level increases, on average, the confidence interval increases in width.https://education.ti.com/en/activity/detail/confidence-levels-for-means
