Students calculate the distance between two points. In this geometry lesson, students define the meaning of the distance between parallel lines. They find the point of intersection of other lines.

Here is a lesson that has learners take a look at corresponding parts of similar triangles, ratios of similarity, reductions and enlargements. They'll manipulate the scale factor (r) to observe the changes in similar triangles and then...

Teach your mathematicians how to identify the properties of quadrilaterals. In this geometry lesson, students solve for missing angles and sides of a special quadrilateral. They use the TI to move the sides around and create different...

Students investigate properties of parabolas. In this algebra lesson, students identify the different paths of a parabola. They use the navigator to make observations of the parabola.

Students solve systems of equations. In this algebra lesson, students graph lines and identify the point of intersection. They identify the function to see if it is a function.

Students explain why a transiting planet causes a periodic dimming in the light from its parent star. They determine the radius of a planet, and its orbital distance, by analyzing data and manipulating equations. Students compare the...

Students balance equations using the correct method. In this algebra lesson, students solve linear equations using a virtual balance beam as a manipulative. They play games to reinforce the concept of equations being and staying balanced.

Seventh graders use their knowledge of multiplication and problem solving to determine the total weight of multiple objects. In this multiplication instructional activity, 7th graders weigh various manipulatives, record the weight, and...

Students apply problem solving procedures and skills to solve a given real life problem by manipulating felt squares to represent the possible combinations for a two color quilt.
