Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

The Golden Ratio. The Divine Proportion. Yup. It's math and art blended into one colorful activity. Young artists combine colored tissue paper circles and parts of circles to create geometric patterns. As a bonus, kids get to figure out...

Students explore the concept of constructions, sketches, and drawings. In this constructions, sketches, and drawings instructional activity, students discuss the differences between constructions, sketches, and drawings through teacher...

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...

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

Pupils practice drawing geometric figures. For this geometry lesson, learners complete an activity that requires them to draw angles and shapes to the nearest degree.

More constructions! For this third installment of a 36-part series, learners watch a YouTube video on creating door trim to see how to bisect an angle. They then investigate how to copy an angle by ordering a given list of steps.

Apply, apply, apply! A measurement lesson applies a number of concepts to help learn a new construction. Scholars learn to divide a segment into n equal parts using a method that uses the Side Splitter Theorem and a method that...

Investigate dilations to learn more about them. The second segment in a series of 16 provides a discussion of properties of dilations by going through examples. The problem set provides opportunities for scholars to construct dilations.

Learners study parallel and perpendicular lines. In this parallel and perpendicular lesson, pupils explore 2-D shapes and determine if the sides are parallel or perpendicular.

In this geometry skills activity, students follow the provided instructions to cut out geometric shapes on the activity and build 5 shapes out of the pieces. Students also complete a graphic organizer regarding the shapes and their...

Students compete in a scavenger hunt to find twenty-two different geometric shapes in natural objects around the school. They practice identification of each geometric shape using a handout then form small groups to search the school...

Fourth graders explore geometry by utilizing pattern blocks. In this pattern lesson, 4th graders analyze two separate pattern block shapes and discuss which one is bigger and smaller. Students collaborate in small groups to create...

Young scholars explore geometry by completing a math worksheet in class. In this shape identification lesson, students identify the characteristics associated with 15 solid geometric shapes. Young scholars identify patterns between...

In this math activity, students construct a model of a rectangular prism by cutting out, folding and taping or gluing this math net. There is no picture of the finished product on the page.

Fifth graders connect their knowledge of polygons and polyhedrons. In this geometric shapes lesson, 5th graders identify and classify two- and three-dimensional objects. Students construct a polyhedron out of polygons and describe their...

Compare two- and three-dimensional shapes and construct three dimensional models from two-dimensional shapes. Diagram the shapes and reflect about the process in writing.

Students explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. Students identify different geometric shapes in the...

Build an interest and appreciation for architecture in your young learners with this fun 10-lesson art unit. Engaging children in using their five senses, the class first observes the environment around them, paying...

Provide your emerging mathematicians with the tools to learn as they incorporate auxiliary lines to solve unknown angle proofs in this continuing segment. They decipher information from a diagram to uncover the missing pieces and...

In this congruent figures instructional activity, students answer ten true or false questions. A sample question reads: "Two triangles are congruent when their shape and size will be the same."

Students select a geometric figure and find an example of the figure in their surroundings. They photograph the figure and write a proof to accompany it. They match photos to proofs.

Geometry students will be ecstatic about these engaging and enlightening end-of-the-year projects! Types of project ideas include interviewing a geometer, an ABCs of geometry poster, an engineering lab report, and origami work. 

In this 3D figure learning exercise, students observe the net of a 3D figure where you open up the figure and tell if it is an accurate representation of that figure. Students complete this for 3 figures.
