Students differentiate between parallel and perpendicular lines. In this algebra lesson, students graph linear equations using the slope intercept form. They classify lines based on their slopes.

Students define and differentiate between experimental and theoretical probability. In this statistic lesson, students play the game "Monty Hall" and use probability to come up with the best strategies to play the game.

Learners investigate finite mathematics using a flow chart. In this algebra lesson, students investigate logic and strategies using flowcharts. Learners compete against each other using different approaches to playing the game.

Students perform an experiment to find the linear relationship between the appllied weight and the bend of the cantilever. In this linear relationships lesson, students follow detailed directions to set up an experiment. They add weights...

Second graders engage in a lesson which focuses on adding two-digit numbers and the regrouping process. They identify when the regrouping process is necessary and make appropriate "trades" to complete an addition problem.

High schoolers solve quadratic equations and identify functions. In this algebra lesson, students graph parabolas and identify properties describing the shape of the parabola. They find the vertex and rewrite the equation in standard form.

Students solve problems using the metric system. In this algebra lesson, students convert between the metric system and the Imperial system. They use these two systems to solve real life problems.

Tenth graders plot points on a coordinate plane. In this geometry instructional activity, 10th graders identify the different quadrants, plots points on a number line and coordinate plane and solve for the midpoint of line segments.

High schoolers differentiate between a relation and a function. In this algebra lesson, students identify a pair of coordinates as being a relation or a function. They analyze graphs for function as they solve word problems.
