Young geometers investigate and apply properties of quadrilaterals.  After a review and discussion of key terms, young scholars use a computer applet to explore four-sided figures and classify them according to their attributes. The...

Middle schoolers construct polygons by plotting points on a coordinate plane. Pupils connect the points and identify which polygons they have drawn. They will need graph paper to carry out the assigned activities. A vocabulary list,...

Students use an Internet tool to explore shapes and how they combine.  In this patterns lesson, students create quilting patterns using various shapes.  Students recognize how the shapes fit together.

What does a geometric farmer drive? A protractor, of course! A set of assessment worksheets prompts learners to use a protractor as they measure angles, name angles, and identify lines. Use the video as a way to...

An exercise in finding the area of polygons by decomposing into triangles and composing into rectangles is the focus of this resource. Make several copies of the worksheet for each participant. Ask learners to use colored pencils to...

As they investigate scaling figures and calculate the resulting areas, groups determine the area of similar figures. They continue to investigate the results when the vertical and horizontal scales are not equal. 

Investigate vectors in standard positions and use the CellSheet application on the TI calculator to find the sum of two vectors. Convert from polar to rectangular coordinates and vice versa, and show graphs of the vectors.

Get learners' minds rotating and reflecting while looking for symmetry. Pupils investigate figures to determine the number of lines of symmetry and if the figure has rotational symmetry. Classmates work together in groups to find out the...

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Students apply the formulas for the area of parallelograms and triangles. Through guided practice, students discover the correct way to apply the formulas. Working in pairs, they write their own problems featuring the formulas.

In this quadrilaterals worksheet, 10th graders identify 10 different figures as they relate to quadrilaterals. They identify and/or make each quadrilateral illustrated on the sheet, including a trapezoid and a parallelogram.

In this geometry puzzle activity, students identify and complete a puzzle that includes 7 different geometrical shapes. They identify and name each shape listed at the bottom. Then, students label every shape in the puzzle with the...

In this word problem worksheet, 5th graders review various mathematical terms by selecting the correct letter that answers each question completely. There are a total of 13 math problems to solve which vary between word problems,...

In this geometry roots activity, 10th graders solve and complete 22 various types of problems. First, they match the geometry word roots on the left with their meanings found on the right side. Then, students list as many other geometry...

Young scholars study geometric shapes, lines, and the primary colors as they create Mondrian-like art prints.

Sixth graders use different measuring tools to measure area, perimeter, and circumference of different shapes. In this measurement lesson plan, 6th graders measure parallelograms, triangles, and circles.

Sixth graders explore different polygons. In this polygon activity, 6th graders examine a rhombus, quadrilateral, parallelogram, and rectangles. Students compare and contrast polygons and research shapes on the Internet.

In this geometry worksheet, students investigate vectors. They add, subtract and identify the magnitude of each vector. There are 4 questions with an answer key.

In this geometry worksheet, students identify the different shapes created by nets. They also identify the intersection of lines and planes. There are 5 questions with an answer key.

Students identify the properties representing quadrilateral. In this geometry instructional activity, students differentiate between special and regular quadrilaterals. They discuss and demonstrate hierarchy of quadrilaterals.

In this mathematical related worksheet, students explore and analyze thirteen key terms associated with geometry in a word search puzzle.

Fifth graders look at the Garrison flag and estimate how big it is. In this measurement lesson plan, 5th graders then calculate the area and perimeter of the flag.

Students define trapezoids and their shapes. In this geometry lesson, students calculate the area of a trapezoid and a parallelogram. They use Cabri software to make investigations.

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