Using a TI Navigator to drag quadrilaterals around to create different shapes, learners learn how to draw midpoints in their quadrilaterals. In this geometry lesson, students solve problems using the properties of quadrilaterals. 

Students identify the number of diagonals for each polygon. In this geometry lesson, students identify the polygons based on their diagonals and the way it intersect. They create visuals using the navigator to see the changes in the shapes.

Students calculate area, perimeter and length of rectangles. In this geometry lesson, students create different formulas for the problem they are being asked to solve. They use the navigator to move the shape around and make observations.

Learners solve systems of inequalities. In this lesson, they identify the solution of the two lines and shade the solution. They identify the boundary line and the region representing the solution.

High schoolers solve matrices using multiplication. In this algebra instructional activity, students identify the properties needed to multiply matrices. They define the terms matrix and dimensions.

Students solve systems of equations. In this algebra lesson, students use matrices to solve linear equations. They use reduced row echelon-form and scalar multiplier to simplify the matrices completely.

Students perform reflections of polygons. In this algebra lesson, students use matrices to calculate the reflection across the x and y axis. They also calculate rotation representing 90 and 180 degrees around the origin of the coordinate...

Statisticians analyze different samples to find independent and dependent events. In this probability instructional activity, pupils predict the outcome and then calculate the real outcome. They create a tree diagram to help predict the...

Young scholars identify the probability of an event occurring. Learners explore the complement of an event in finding why an event will not happen. They also explore basics of probability within algebra.
