In this math instructional activity, students study the properties of plane shapes and solid figures. Students fill out a chart after they have calculated the number of flat surfaces, edges and vertices.

Sixth graders graph translations (slides) and reflections (flips) on a coordinate plane. They visualize and identify geometric shapes after applying transformations on a coordinate plane. Finally, 6th graders write a paragraph telling...

Students explore graphing. In this math lesson plan, students graph ordered pairs in the coordinate plane, write the coordinates of points shown on a plane, and create designs or pictures using ordered pairs.

Sixth graders complete several activities that involve coordinates and graph paper. They visualize and identify geometric shapes after applying transformations on a coordinate plane. Finally, 6th graders draw and label a coordinate...

In this congruence statements worksheet, 10th graders solve and complete 16 various types of problems. First, they complete each congruence statement listed. Then, students graph each set of points on the coordinate plane provided. They...

Students graph coordinate points to create a picture of Snoopy. In this coordinate point lesson, students read a book and learn about Rene Descartes' invention, the coordinate grid.  Students graph a surprise picture on...

In this Froot Loop to the Max worksheet, students complete 21 different sets of ordered pairs. They plot each of the ordered pairs listed on the sheet, connecting them in order from #1 through #21. Then, students determine whether it is...

In this transformations instructional activity, students identify the coordinates of triangle MNO after completing three translations and one reflection. Students use the triangle MNO with given coordinates to complete each...

Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this instructional activity. They make a set of tangrams and use them to...

This is an interesting geometry problem. Given the figure, find the area of a triangle that is created by the intersecting lines. The solution requires one to use what he/she knows about coordinate geometry, as well as triangle...

Sequences and series are traditionally thought of as topics for the pre-calculus or calculus class, when learners are figuring out how to develop limits. But this unit uses patterns and slopes of linear functions in unique ways...

Working in groups, pupils plot three points on the coordinate plane representing three different parabolic paths. Using a calculator, they determine the quadratic regression equation for their models. Each team then figures out the...

Third graders construct tangrams. In this tangrams lesson, 3rd graders manipulate basic shapes to construct tangrams. Students explore how shapes can be combined in different ways and develop spatial sense.

In this angles and figures review worksheet, 10th graders solve and complete 39 different multiple choice problems. First, they find the length of a line between two given points. Then, students name the type of transformation and the...

In this rotational symmetry worksheet, 10th graders identify and compare 10 different figures illustrated on the sheet. They write the order of rotational symmetry seen in each figure as compared to the others. They also define an object...

Students explore the concept of quadrilaterals. In this quadrilaterals lesson, students use the slope formula, midpoint formula, and distance formula to justify that a given quadrilateral is a parallelogram.

Fifth graders, with a partner, create tessellation patterns by playing 10 by 10 Tessellations. They need to use critical thinking skills to decide if pattern block plane figures tessellate and how each block best fits into the pattern.

First graders view congruent shapes on a white board and define what congruent means.  In this congruent shapes lesson, 1st graders recognize which shapes are congruent and which aren't  Students complete a giant worksheet in...
