Adding and Subtracting Decimals
Students' learn about adding and subtracting decimals.https://education.ti.com/en/activity/detail/adding-and-subtracting-decimals
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
Box Plots
In this lesson, students plot the two extreme values (minimum and maximum), the lower quartile (LQ), upper quartile (UQ), and the median (a five-number summary) on a number line to create a graph called is a box plot.https://education.ti.com/en/activity/detail/box-plots-bc
What's the Trig?
Students will be introduced to right triangle trigonometry. They will use the TI-89 and Geometer's Sketchpad to construct a right triangle and calculate sin, cosine, and tangent of various acute angles. (Topic - Right Triangle Trigonometry)https://education.ti.com/en/activity/detail/whats-the-trig
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
Quilt Blocks
Students will see how fractions, decimals, and percents are interrelated, then explore and learn how to convert between them. Students will also practice estimating.https://education.ti.com/en/activity/detail/quilt-blocks
Going in Circles - Inscribed Angles
This lesson has students discover properties of inscribed angles in a circle. Students use the Geometer's Sketchpad application for the TI-89 to construct a circle and an inscribed angle. (Topic - circles)https://education.ti.com/en/activity/detail/going-in-circles--inscribed-angles
What is a Variable?
In this lesson students evaluate expressions, write expressions that correspond to given situations, and use expressions and formulas to solve problems. Students also examine a product of the form ax for given integer values of a in terms of how the value of the product changes for a one unit cha...https://education.ti.com/en/activity/detail/what-is-a-variable-bc
What is an Equation?
In this lesson students begin by establishing the difference between an expression and an equation. Students then investigate expressions and equations to develop what it means to have a solution to an equation.https://education.ti.com/en/activity/detail/what-is-an-equation-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
