NCTM Geometry Standard covered: Analyze characteristics and properties of 2- and 3-dimensional geometric shapes and develop mathematic...https://education.ti.com/en/activity/detail/exploring-the-diameter-and-circumference-of-a-circle
Extension: Parallel Lines and the Sum of the Angles
Students construct a line parallel to the base of a triangle and measure the angles formed. They use the construction to prove that the sum of the measures of the interior angles of a triangle is 180 degrees.https://education.ti.com/en/activity/detail/extension-parallel-lines-and-the-sum-of-the-angles
Ordering Fractions, Decimals, and Percents
Students explore numbers and number representations for fractions, decimals, and percents.https://education.ti.com/en/activity/detail/ordering-fractions-decimals-percents
Statistical Plots
This activity gives students an opportunity to select and create the most appropriate graph to represent a given data set.https://education.ti.com/en/activity/detail/statistical-plots
Exploring the Orthocenter of a Triangle
In this activity, students use the Cabri™ Jr. tools to draw altitudes in a triangle. They construct a line perpendicular to a given line and through a given point. NCTM Geometry Standard covered: Analyze characteristics and properties of 2- and 3-dimensional geometric shapes and develop mathemat...https://education.ti.com/en/activity/detail/exploring-the-orthocenter-of-a-triangle
We Have the Same Birthday
In this activity, students use simulations to answer a popular question involving probabilities. They will use the randInt and mean commands to determine the average number of people that need to be in a room to share a birthday.https://education.ti.com/en/activity/detail/we-have-the-same-birthday
Vertical Angles
In this activity, students visualize and explore the angles that are formed when two lines intersect. By measuring angles formed by intersecting lines, they enhance their understanding of vertical angles, supplementary angles, and a linear pair.https://education.ti.com/en/activity/detail/vertical-angles
Using Venn Diagrams to Find the GCD
In this activity, students use Venn Diagrams to classify numbers. They will first classify multiples of 3, 5, and 6, deciding where to place the least common multiple. Then, students will use the TI-84 Plus C Silver Edition™ integer division and remainder features to help them classify fact...https://education.ti.com/en/activity/detail/using-venn-diagrams-to-find-the-gcd
The Variables of Renting
In this activity, students will identify what a variable is, construct a table of values, graph the ordered pairs from the table, and use the TI-84 Plus C Silver Edition to graph the equation.https://education.ti.com/en/activity/detail/the-variables-of-renting
The Same Name Game
In this activity, students explore the meaning and purpose of equivalent fractions. They also practice writing fractions that meet a given criteria.https://education.ti.com/en/activity/detail/the-same-name-game
Estimating Square Roots
In this activity, students develop an understanding of the relationship between a number and its square root. They will first recognize perfect squares and order them from least to greatest with other numbers. Then students will estimate the square root of a number using perfect squares.https://education.ti.com/en/activity/detail/estimating-square-roots
Drawing Conclusions
This activity introduces students to the concept of collecting and analyzing data and using conjectures to formulate new questions.https://education.ti.com/en/activity/detail/drawing-conclusions
Comparing Area of Rectangles
In this activity, students discover the relationship between a change in the dimensions of a rectangle and the change in the corresponding area.https://education.ti.com/en/activity/detail/comparing-areas-of-rectangles
Algebra vocabulary terms
This StudyCards™ activity includes the definitions for 15 algebra terms for which the students need to identify the correct vocabulary term.https://education.ti.com/en/activity/detail/algebra-vocabulary-terms
Calculating Unit Prices
In this activity, students will compare ratios with different denominators, and then with common denominators. They will also find unit rates.https://education.ti.com/en/activity/detail/calculating-unit-prices
Calculating Sale Prices
In this activity, students will find discounts and sale prices for items selling at 20% off and 40% off by using tables. They will then find the general rules, using a variable, for finding those discounts and prices.https://education.ti.com/en/activity/detail/calculating-sale-prices
