Solving Inequalities Graphically
Students will solve inequalities graphically by setting bounds on the graph that represent the portions of the graph that satisfy the inequality. Each of the inequalities presented in this activity represent real-world situations, which should aid in students understanding the concept of inequali...https://education.ti.com/en/activity/detail/solving-inequalities-graphically
Radio Station KTNS
This lesson involves determining the distance one can hear a radio station as a function of the range of the station.https://education.ti.com/en/activity/detail/radio-station-ktns
Radical Functions
Students use a nomograph to investigate functions defined by square roots. Nomographs consist of two or more parallel axes, one for inputs and another for outputs. Input, output pairs that belong to the function are graphed as corresponding points on the axes connected by a ray drawn from the inp...https://education.ti.com/en/activity/detail/radical-functions_1
Properties of Special Quadrilaterals
Explore properties of some special quadrilaterals using segments to build quadrilaterals and explore their angles.https://education.ti.com/en/activity/detail/properties-of-special-quadrilaterals
Angles of a Triangle
In this activity, students will measure angles and investigate the relationships between interior and exterior angles of a triangle. They understand the definition of interior angles, exterior angles, adjacent angles, supplementary angles, and remote interior angles.https://education.ti.com/en/activity/detail/angles-of-a-triangle
Triangle Inequalities
This activity will help students visualize the properties of triangles stated in the theorems. By dragging the vertices, the students can see that the properties hold regardless of the size of the triangles and which sides are the longest or shortest.https://education.ti.com/en/activity/detail/triangle-inequalities_2
Hey, Ortho! Whats Your Altitude?
