Students build polygons on their geoboards. In this geometry lesson plan, students build and then draw it on paper and label it. Students then switch with a partner to try an make a symmetrical shape.

In this math worksheet, students eliminate the parameter to find a Cartesian equation of the curve given by the parametric equations.

Pupils investigate the usage of parallel and perpendicular shapes in the real world. For this geometry lesson, students investigate shapes for properties that are related to the real world. They relate all the properties of shape tot he...

Students are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three concepts.

Pupils explore different types of quadrilaterals. Students define the terminology used with quadrilaterals. They create particular quadrilaterals based on specific characteristics of the quadrilaterals using an online tool.

In this math worksheet, students look for the properties related to each shape and then fill in the graphic organizer with the categories needed.

In this math worksheet, students complete the practice exam that asks for the solution to the parametric equation. Also they name the perpendicular line in relation to it.

Young scholars examine geometric shapes. In this geometric shape lesson plan, students examine how geometric shapes flip, turn, and slide to create a pattern. Young scholars analyze the role that quilts played in helping slaves escape...

In this grade 5 reading quiz, 5th graders complete a 26 question multiple choice quiz covering a variety of grade 5 reading concepts. Answers may be submitted on-line.

Third graders represent fractions as part of a whole. In this fractions lesson, 3rd graders use manipulatives to show how a fraction is a part of a whole. This lesson includes individual practice and an assessment instead of direct...

Students examine new shape possibilities by combining two and four triangles using manipulatives.

Young scholars, in groups, estimate measurments and then select the tools needed and measure various items at Black Bayou Lake refuge.

Third graders use fractions to describe part of a set. In this fractions lesson, 3rd graders are introduced to fractions through a book and use pattern blocks to describe a fraction as a part of a set. This lesson includes a scripted...

Students create their own Chinese tangrams using in-class direction and prior knowledge in this two-day instructional activity for the early elementary classroom. Chinese toys are also explored.

Students explore the concept of minerals. In this minerals lesson, students discuss how cooling affects the size of crystals. Students discuss how the structure of minerals is a tetrahedron. Students discuss the structure of silicates...

[Free Registration/Login may be required to access all resource tools.] In this lesson students estimate actual areas of parallelograms in scale drawings. Students examine guided notes, review guided practice, watch instructional videos...

Try to figure out the area of this challenging shape. In order to view the images, you will need to use JavaSketchpad.

These activities provide an opportunity for students to explore the area formulas for triangles, trapezoids, and parallelograms.

Given composite figures (combinations of rectangles, squares, parallelograms, trapezoids, triangles, semicircles, and quarter circles), students will be able to determine expressions for the area as well as calculate the area of the figure.

Given information about composite fiugres, the student will determine the area of composite 2-dimensional figures comprised of a combination of triangles and parallelograms using appropriate units of measure.

Demonstrates how to calculate the area of two-dimensional shapes using formulas. Covers parallelogram, triangle, trapezoid, and circle. Includes a video modeling how to find the area of a circle and a triangle. [0:59]

Students will find the area of a parallelogram and the area of a triangle.

Students review the definition and area formula for the rectangle, square, parallelogram, triangle, trapezoid, and circle.

Calculate the Area of a Trapezoid This Concept Handheld Software Application reviews the definition and area formula for the rectangle, square, parallelogram, triangle, trapezoid, and circle.
