Learners identify names of angles. They use a large clock to demonstrate angles using certain times of day. Given a geoboard, students create figures with acute, right, and obtuse angles.

Students explore the basic geometric shapes and geometric shape vocabulary through the use of geoboards and virtual geoboards. They create a variety of shapes with a partner, build ten different rectangles on their geoboards, and...

Students explore models of three-dimensional shapes. In this geometric shapes lesson, students use hands-on manipulatives to explore three-dimensional shapes. Students predict whether each shape will roll or slide.

Students construct two dimensional models to illustrate squared numbers. In this geometry instructional activity, students use graph paper and an x/y axis to build squares exponentially. Students identify powers and relationships between...

Students explore geometric solids. In this geometry lesson, students listen to the book The Greedy Triangle by Marilyn Burns, then work in groups to sort geometric solids into various categories. Students define geometric solids...

Students explore geometric shapes.  In this kindergarten geometry lesson, students create a fall quilt consisting of three different paper geometric quilt squares that when assembled form a scarecrow, a pumpkin, and a crow. ...

In this math learning exercise, students investigate reflections of geometric shapes by completing 15 problems. Students analyze a picture of a geometric figure drawn on a dot grid and draw the reflection.

In this geometric solids activity, students examine 4 different solid shapes then record the number of faces, the number of edges and the name of each shape.

Your class examines a series of shapes and discusses how we know that they are not circles. In this way, you begin to acquaint them with the properties and parts of this geometric figure. Then, teach them how to use a protractor to...

In this geometry review worksheet, 10th graders solve and complete 33 different problems that include identifying various geometric figures and parts of a circle. First, they find the radius of each circle given its diameter. Then,...

Students explore differents types of triangles and quadriaterals. For this polygon lesson, students  model identify and compare two and three dimensional geometric figures. Students create tangrams and discover the difference...

Learners explore quantum physics by participating in several class activities. In this space-time lesson, students discuss the concepts of time traveling and the anatomy of an atom. Learners draw geometric figures and utilize string to...

Sstudents explore and analyze the properties of geometric areas.  In this geometry lesson, sstudents use technology to simulate spinners and dartboards in order to fing areas of circles and sectors of circles and compare and...

Fifth graders use formulas for calculating areas of squares and rectangles to find area of complex figure, compare their own ideas with their classmates' ideas, and recognize that there are multiple methods for finding area of complex...

In this math worksheet, students read information about 6 types of polygons and their sides and angles. Students then answer 5 questions about the geometric figures.

In this squares worksheet, students analyze a group of geometric figures and look for squares. Students color all the squares they see.

In this shape and figure descriptions worksheet, students name the shape described and draw it. Students complete this for 2 shapes.

In this similar-congruent worksheet, students determine measures of unknown angles, draw congruent shapes and determine whether shapes are congruent. A reference web site is given for additional activities.

Learners of all ages investigate area and perimeter through pentominoes. In this geometry lesson plan, students calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent shapes....

Show your math class how to use vectors in adding complex numbers. Vectors represent complex numbers as opposed to points in the coordinate plane. The class uses the geometric representation to add and subtract complex numbers and...

Augment a unit on parabolas with an instructive math activity. Pupils graph parabolas by examining the relationship between the focus and directrix. 

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...

Middle schoolers work in small groups to make various geometric solids with Play-Doh. They use fishing line to make cuts and observe the shapes of the cross-sections. Pupils complete an assessment in which they answer questions such as:...

High schoolers use diagrams of the constellation Orion and the constellation Ursa Major which show the distances between the stars of the constellations. They calculate the perimeters of each, find the average distance of the stars for...
