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...

Fourth and fifth graders learn to classify quadrilaterals and use more than one name for each. They follow the directions and classify three quadrilaterals. There are also activities which can be done with a partner.

Learners study area and quadrilaterals. In this multiplication and area lesson, students use Polystrip models to change rectangles to form different parallelograms. Learners find the area of the models use a Geometer Sketchpad to find...

In this area worksheet, students solve for the area of rectangles, parallelograms, triangles, trapezoids, kites, regular polygons, circles, and surface area.  The worksheets is divided into seven different sets of problems.

Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.

Students use numbers as descriptors. For this mathematical inquiry lesson, students use numbers to describe, classify, and compare plants. Students are made aware that numbers can be used to describe things in the world around them.

In this geometry worksheet, students determine if a figure is a quadrilateral. If so, students continue to answer questions to determine whether it is a square, diamond, rhombus, rectangle, parallelogram or trapezoid.

Second graders complete a variety of activities surrounding a unit on China and Chinese culture.

Fifth graders find the area and volume of buildings. In this architecture instructional activity, 5th graders look at the drawings of three historic Tennessee buildings. They use these to help find the area and volume of the building. 

Using a TI Navigator to drag quadrilaterals around to create different shapes, students learn how to draw midpoints in their quadrilaterals. In this geometry lesson, students solve problems using the properties of quadrilaterals. 

In this street map worksheet, learners observe the street map and answer short answer questions using the map. Students complete 4 questions.

Students show the correlation between quadrilaterals, parallelograms, rectangles and squares.

In this geometry worksheet, students match 5 shapes to several terms, determine the radius and diameter from 2 diagrams, and find the area and perimeter of 3 problems.

Students create identify properties of trapezoids. In this geometry lesson, students calculate the area of given trapezoids and review the area formula for parallelograms. They draw a correlation between the area of a trapezoid and that...

Learners explore a variety of geometric shapes, name them, and list their characteristics. The shapes are transposed into structures and checked for accuracy.

Students are given patterns of trapezoids and are to calculate the area of one trapezoid by using both patterns. They should form a parallelogram and calculate the area. They practice this technique until there is understanding.

Students calculate the area and diameter length of a circle. In this geometry lesson, students investigate the use of pivots as they review parts of a circle. They create a circle using cardboard and label all the parts.

In this tessellations instructional activity, 10th graders solve 6 different types of tessellation problems that includes drawing. First, they define polygon, regular polygon, tessellation, regular tessellation, and semi-regular...

Learners explore the concept of quadrilaterals. In this quadrilaterals lesson, students use the slope formula, midpoint formula, and distance formula to justify that a given quadrilateral is a parallelogram.

Seventh graders complete activities to further their understanding of area formulas. In this area lesson, 7th graders watch as the teacher uses Polystrips to model parallelograms. Students find the area of a rectangle and answer...

Students use construction technology to identify and find relationships between the attributes of various quadrilaterals. They make and test conjectures about the distinguishing properties of parallelograms, rectangles, rhombuses,...

Students read the book The Math Curse by Jon Scieszka and study geometry. In this geometry lesson, students identify geometric shapes and their properties. Students create a geo-critter.

Fifth graders use estimation to solve word problems. In this fractions lesson, 5th graders decide whether or not an answer to a work problem is reasonable by applying their knowledge of fractions, decimals and estimation. This lesson...

Students investigate shapes. In this dimension and orientation of shapes instructional activity, students identify and color shapes, use shape stamps to form animals, glue shapes together to make other objects and describe how...
