Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Students discover the plain shapes that make up space shapes. They match and stamp shapes together, and create their own space shapes. Students apply what they know about space shapes to make amuseum of shapes. Finally, they compare...

Students study polygons. In this math lesson, students play a game in which they learn the classification system for polygons. Students identify the properties of quadrilaterals.

In this geometry worksheet, students cut out a rectangular prism net. They cut along the dotted lines as indicated the scissors icon, and fold the piece along the solid lines to form the three-dimensional shape. There are no directions...

Fifth graders will be predicting and describing the results of sliding, flipping, and turning two-dimensional shapes. They will also understand patterns so they can describe, extend, and make generalizations about geometric and numeric...

Use this geometry review worksheet to have learners complete nine problems involving transformations, area, volume, and unit conversions. They answer one multiple choice question on estimating lengths.

This can be used as a critical thinking exercise in congruence or as a teaching tool when first introducing the concept. Four octagons are arranged in such a way that a square is formed in the middle. With this information, geometry...

Sixth graders explore three-dimensional objects. In groups, they create and decorate their own polyhedron design. After identifying the faces, vertices, and edges of the polyhedron, 6th graders determine a relationship between the...

In this nets of 3 dimensional figures worksheet, students determine which given figures will make given nets, then name a set of 4 shapes.

In this nets of figures activity, students determine which given shapes will make a shown net, then name the shapes uses. A reference web site is given for additional activities.

Fifth graders explore angles by using protractors. They recognize, describe and determine the surface area and volume of three-dimensional shapes. Students recognize the right angle, acute angle, obtuse angle and vertex. They identify...

Pupils identify shapes and manipulate 2 and 3 dimensional objects. They view objects from different perspectives and review relative positions (near, far, between). They sing a shape song.

Students complete worksheets where they calculate the perimeter of polygons. In this perimeter of polygons lesson plan, students divide complex shapes into simple shapes to find the perimeter.

Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...

Students recognize and name two-dimensional and three-dimensional geometric figures. One group of students will extend the study of polygons to quadrilaterals while another group of students will extend the study of polygons to...

Learners create a three-dimensional book about landscapes. They must show their understanding of shape, color and balance.

Students create different shapes on grid paper.  In this two-dimensional geometry instructional activity, students take turns outlining a shape made of six squares on the graph paper.  They identify all shapes they see once...

Second graders organize solids into categories, depending upon whether they will roll, slide or do both on a home made ramp. Students describe and compare attributes of three-dimensional geometric solids.

Pupils create a Holocaust memorial. In this interdisciplinary lesson, students use geometric shapes or forms to create a Holocaust monument.

Learners explore the concept of geometric shapes. In this geometric shape instructional activity, students play bingo to review geometric shapes. Learners identify the shape being described by the teacher and put a marker on their bingo...

Third graders draw shapes that are congruent. In this congruency lesson, 3rd graders use grid paper to draw letters and figures and their congruent partners. They complete a worksheet while working in a whole class setting with the...

Students investigate triangles. In this shapes geometry lesson, students define and state the attributes for equilateral, scalene, and isosceles triangles. Students locate the prefix "tri" in a variety of words and make connections with...

Third graders explore the attributes of polygons. In this geometric shapes lesson, 3rd graders review quadrilaterals, squares, rectangles, triangles, pentagons, hexagons, and octagons in order to create hanging polygons. Students then...

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...
