Angle Theorem
Students use the Cabri Geometry II Plus software to investigate the relationship between angle and ratio in a right triangle.https://education.ti.com/en/activity/detail/angle-theorem
Proportional Flag
Students will use the concepts of similarity to create a scale drawing of the national flag, that is large enough to cover most of a football field.https://education.ti.com/en/activity/detail/proportional-flag
What's the Angle?
Students discover properties of interior and exterior angles of convex polygons using the TI-89 and Geometer's Sketchpad. (Topic - Interior and Exterior Angles of Convex Polygons)https://education.ti.com/en/activity/detail/whats-the-angle
What's the Spin?
Students discover properties of rotations using the TI-89 and CABRI Geometry II by rotating a triangle around a point and through a specified angle. They will discover the definition of a rotation. (Topic -- Rotations and their relation to reflect)https://education.ti.com/en/activity/detail/whats-the-spin
Stepping Stones
Students use volume formulas and proportional reasoning to calculate the amount of concrete needed to make stepping stones of a specific size.https://education.ti.com/en/activity/detail/stepping-stones
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
Slam Dunk!
Students will use radius, diameter, length, width, and height to find volume of spheres and prisms as well as area of circles and rectangles. They will discuss when to use a two-dimensional measurement vs. a three-dimensional measurement using spatial reasoning.https://education.ti.com/en/activity/detail/slam-dunk
Banquet Meal
Students use proportional reasoning skills to increase a family-size recipe to a banquet-size recipe.https://education.ti.com/en/activity/detail/banquet-meal
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
Looks Right
Students use the Cabri Geometry II Plus software to determine which given triangle retains its basic shape after its vertices are dragged around the screen.https://education.ti.com/en/activity/detail/looks-right
Cottage Water Problem
Students use the Cabri Geometry II Plus software to solve a geometry problem. They move the vertex point that is common to two right triangles along the base to find the smallest possible sum of the length of the hypotenuse.https://education.ti.com/en/activity/detail/cottage-water-problem
Pizza Extravaganza
Students will conduct a survey of the class to determine favorite pizza toppings. They use this sample information to predict the preferred toppings for the school and use the TI-15 to help them with the calculations to plan a school-wide pizza party.https://education.ti.com/en/activity/detail/pizza-extravaganza
Making Cookies
Students will reduce a cafeteria recipe to suit a household recipe. They use compatible numbers to choose smaller measurements while retaining the original proportions.https://education.ti.com/en/activity/detail/making-cookies
Meal Manager
Students will use percentages and proportional reasoning skills to solve problems.https://education.ti.com/en/activity/detail/meal-manager
Modeling Median Incomes
In this activity, students investigate and examine the data underlying the claim that women’s income is catching up to men’s income.https://education.ti.com/en/activity/detail/modeling-median-incomes
What is an Exponent?
Why are exponents useful and how do they behave? An exponent indicates how many times the base to which it refers is a factor; i.e., in , the 4 indicates that the base, 3, is used as a factor four times. This lesson focuses on how the definition can be used in a variety of situations to make sens...https://education.ti.com/en/activity/detail/what-is-an-exponent--bc
Equations and Operations
In this lesson students investigate the relationship between the solution to an equation and the solution to a new equation formed by adding, subtracting, multiplying, or dividing one or both sides of the original equation by a numerical value. Students develop an understanding of “solution...https://education.ti.com/en/activity/detail/equations-and-operations-bc
Let's Count the Ways
Students will be introduced to the different ways to calculate numbers of outcomes, including using the counting principle. They will also evaluate expressions using permutations of data without repeat elements, both manually and on the TI-34 MultiView™ calculator.https://education.ti.com/en/activity/detail/lets-count-the-ways_1
Ready, Set... Solve!
In this coding activity, students will create a fast-paced game to help practice solving multi-step equations.https://education.ti.com/en/activity/detail/ready-set-solve
