Student will discover the relationship between the height of a box with a triangular base and its volume and student will find the height that will produce the maximum volume of the open-topped box.https://education.ti.com/en/activity/detail/the-triangular-box-problem-and-extension
Application of Slopes
Students will apply the concept of slope to a real-world problem about building a staircase. They will use the slope ratio, vertical change over horizontal change, to find the slope of staircase. Then, students will recognize how a positive or negative slope applies in a real-world situation.https://education.ti.com/en/activity/detail/application-of-slopes
Common Denominator
In this activity, students will use an interactive model that multiplies the fraction by "1" to help determine the common denominator. Then they will use what they have learned to add and subtract fractions without the same denominators.https://education.ti.com/en/activity/detail/common-denominator_1
Pi Song - Little Help
Solving literal equations with Pi. In this activity, students will explore formulae that have Pi in it. Animations and multiple choice, self-check questions, make this activity accessible to Algebra students. The equations make this activity of interest to geometry and physics classes for a short...https://education.ti.com/en/activity/detail/pi-song--little-help
Families of Rectangles
Students create a family of similar rectangles and then write the equation of the curve that will connect the upper-right vertex of each rectangle. Students will then create a family of rectangles that have the same area and will write the equation of the curve that connects the upper-right verti...https://education.ti.com/en/activity/detail/families-of-rectangles
Triangles and Slope - Is the Triangle Possible?
Students will construct triangles that match specific criteria. If it is possible to construct the triangle, the students have to construct the triangle and state the slope of each side. If the triangle is impossible to construct, the students must write a detailed explanation as to why it is im...https://education.ti.com/en/activity/detail/triangles-and-slope--is-the-triangle-possible
Find the Equation of the Line
Teachers and/or students will look at given information (two points, a point and a slope, a point and a parallel line, and a point and a perpendicular line) and have to find the linear function that works. As the activity is occuring on the calculator, the students have a worksheet to record the...https://education.ti.com/en/activity/detail/find-the-equation-of-the-line
Exploring Slope, Including a Study of Parallel and Perpendicular Lines
This activity contains 4 problems. The first 2 allow the students to notice relationships of slopes and y-intercepts to the location of lines.
