Tri This!
Students investigate linear equations that form a triangle and determine which vertex is a solution to a system of equations.https://education.ti.com/en/activity/detail/tri-this_1
Working Hard or Hardly Working?
Students analyze univariate and bivariate data. Questions are posed for discussion, further research, and algebraic problem solving.https://education.ti.com/en/activity/detail/working-hard-or-hardly-working_1
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
Applications of Parabolas
In this activity, students will look for both number patterns and visual shapes that go along with quadratic relationships. Two applications are introduced after some basic patterns in the first two problems.https://education.ti.com/en/activity/detail/applications-of-parabolas_1
Beat the System
