For this parallelograms worksheet, 10th graders solve 8 different types of problems related to measuring various parallelograms. First, they use the figure, a parallelogram, illustrated at the top to solve each problem. Then, students...

In this identifying similar triangles worksheet, 10th graders solve 5 different proofs related to similar triangles. First, they identify the similar triangles in each figure and explain why they are similar, using the information to...

In this geometry worksheet, students draw a line from each geometric shape shown on the left to the matching shape on the right side of the page. They work with plane figures such as a triangle, an oval, a rectangle, and a hexagon.

In this math worksheet, students build a truncated dodecahedron. This is a solid shape with 12 regular decagonal faces and 20 equilateral triangular faces. Students build this shape to assist in developing their cognitive and geometric...

In this finding the area instructional activity, students solve 6 problems in which the area of a square or rectangle is calculated. The instructions and examples provides hints and formulas.

In this math worksheet, students use the math net pattern to construct a model of a rectangular prism. Students cut, fold and tape this 3 dimensional figure.

Pupils explore geometry by creating jewelry in class. In this polygons lesson, students identify different shapes and characteristics while creating polygon figures from construction paper. Pupils utilize a multitude of shapes to...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Build a definition of congruence from an understanding of rigid transformations. The lesson asks pupils to explain congruence through a series of transformations. Properties of congruence emerge as they make comparisons to these...

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Just what does it take to show two rhombuses are similar? The assessment task asks pupils to develop an argument to show that given quadrilaterals are rhombuses. Class members also use their knowledge of similar triangles to show two...

Can your kindergartners recognize shapes? What about when they are in different orientations? Youngsters study groups of shapes to determine which have the same shape and size. Two of the groups have triangles and ovals, and the other...

The Hopewell people of the central Ohio Valley used right triangles in the construction of earthworks. Pupils use the Pythagorean Theorem to determine missing dimensions of right triangles used by the Hopewell people. The assessment task...

Examine repeating and intricate patterns with a study of M.C. Escher and a related art activity. Pupils view and discuss the artwork before creating their own tessellating patterns. Step-by-step instructions for creating a template are...

Pupils analyze a pattern of conference tables to determine the number of tables needed and the number of people that can be seated for a given size. Individuals develop general formulas for the two growing number patterns and...

Sew up pupil interest with an engaging, hands-on lesson. Learners first design a sports bag given constraints on the dimensions of fabric. They then evaluate provided sample responses to identify strengths and weaknesses of included...

How well do your classes understand scale? You'll certainly know after they answer the set of eight questions from an informative and helpful presentation. Questions include items from coordinate geometry, similar triangles, and scale...

Strengthen young geometric muscles with this exercise in finding surface area and volume. Six problems provide practice at determining the surface area and volume of two solid figures shown in cubic units, deciding which to find given a...

Why was Pythagoras so obsessed with squares? The assessment task posits the question of whether the geometric interpretation of the Pythagorean Theorem holds for figures other than squares. Scholars first consider the case of semicircles...

Students explore tessellations. In this shapes and geometry instructional activity, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.

Students make three dimensional shapes with nets. In this nets lesson, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They use the...

Students explore the concepts of length, perimeter, and area. In this math lesson, students use Shape Explorer to practice finding length, perimeter, and area.

Students reflect, rotate, translate, and dilate figures in the Cartesian coordinate plane using grid paper and dot paper. They use transformations (i.e., reflections, translations, rotations, and dilations) to describe geometric patterns...

Young scholars calculate the volume and surface area of each shape. For this geometry lesson, students use nets and other three dimensional polygons to create visuals of the volume of a shape. They define important vocabulary words...
