Sixth graders use geoboards and dot paper to experiment with geometric concepts. In this geometry lesson plan, 6th graders complete four activities using geoboards or dot paper including naming points on a coordinate plan and finding the...

Students begin the lesson by identifying what a polygon is and hypothesizing how many struts (diagonals) it would take to make a polygon rigid. They watch a "Magic School Bus" episode then experiment with various shapes to make a...

Students explore the properties of rectangular prisms. In this geometry lesson, students identify properties of two and three dimensional shapes. They use Cabri technology to create polygons and solve problems.

Pupils define properties of rectangular prisms. In this geometry instructional activity, students identify the relationship between two and three dimensional objects. They use Cabri technology to graph their figures.

Students identify properties of trapezoids. In this geometry lesson, students are put into groups and use computer programs to analyze polygons. They drag and move the shapes around as they make predictions.

Students identify properties of parallelograms. In this geometry lesson, students label polygons as parallelogram or not. They define and label the properties of a kite.

In this geometry worksheet, students define and draw quadrilaterals. They differentiate between the different shapes. There are 3 questions with an answer key.

In this quadrilaterals worksheet, 10th graders solve and complete 34 various types of problems. First, they fill-in the family tree with the names of the shapes of quadrilaterals shown. Then, students list the quadrilaterals that have...

In this right triangles learning exercise, 10th graders solve and complete 14 various types of problems. First, they find the perimeter of the isosceles trapezoid shown. Then, students find the measures of each marked side of a right...

Learners investigate the area of various figures. They construct triangles and quadrilaterals using Cabri Jr. and discuss the relationships between different angles, side lengths, and figures.

In this test for parallelograms worksheet, students solve 15 short answer problems. Students determine if a given sketch is a parallelogram given angle measures and/or side lengths. Students use knowledge of parallelograms to find...

In this perimeter worksheet, 10th graders solve and complete nineteen various geometry problems. First, they find the length of given segments in addition to the perimeter of a kite. Then, students find the value of a variable so that...

Students examine the idea of "regularity" as it pertains to geometry.  For this geometry lesson students complete several assignments that are part of trihedral angles and regular polyhedrons.

Second graders use geoboards to model polygons and to practice finding lines of symmetry.

For this quadrilaterals worksheet, 10th graders solve and complete 10 different problems that include identifying various quadrilaterals. First, they indicate whether the statements are true or false for each. Then, students determine...

In this trapezoids worksheet, 10th graders solve 5 different problems related to trapezoids and applying the appropriate theorem. First, they define a trapezoid, including its bases, legs, and base angles. Then, students use the...

In this prisms worksheet, 10th graders solve and complete 6 different types of problems. First, they find the volume of a right prism with equilateral triangles as bases. Then, students find the volume of a right prism with isosceles...

In this squares and rhombi instructional activity, 10th graders solve 8 different problems with quadrilaterals, especially the square and rhombus. First, they use the given rhombus and the given information to find the value for each...

In this math worksheet, learners draw quadrilaterals and also find the sums of the inner angles for each. They practice drawing rhombuses as unique quadrilaterals.

In this Pascal worksheet, students begin at the center of a rhombus to identify the number of ways the word "Pascal" may be found.  This one-page worksheet contains 1 puzzle.  The answer is provided at the bottom of the page.

Students analyze a drawing of a regular octagon inscribed in a circle to determine angle measures, using knowledge of properties of regular polygons and the sums of angles in various polygons to help solve the problem. They use...

What does it mean for a quadrilateral to be cyclic? Mathematicians first learn what it means for a quadrilateral to be cyclic. They then investigate angle measures and area in such a quadrilateral.

Class members complete an assessment task by identifying whether statements about triangles and quadrilaterals are always true, sometimes true, or never true. They then participate in a sorting activity with the same objective.

Students analyze the measurements of rectangles. In this analysis lesson, students will investigate patterns by looking at ratios. Students will also hypothesize the probability of a ball going into a certain pocket when playing pool....
