By splitting a rectangle into equal parts, scholars can see area as well as calculate it. First, they determine the area of a rectangle given its side lengths. Then, they use the space provided to segment it into four equal parts,...

Fifth graders play Battleshapes which is a variation of Battleship with geometry. In this geometry lesson, 5th graders get a graph paper with four quadrants. They call out coordinate points and attempt to sink their opponents shapes. 

Young scholars analyze characteristics of geometric shapes. They find shapes in their environment, and communicate why it is like the shape of their choice and not like another shape.

First graders analyze characteristics of geometric shapes. They identify, describe, and create simple geometric figures. They analyze characteristics of geometric shapes and determine the defining attributes of a circle,...

High Schoolers investigate the question of whether or not the area of square can be trisected. In this instructional activity, they use geometry software to answer the questions and determine what conditions are necessary to the three...

Learners investigate octagons using words and shapes. In this geometry lesson, students discuss the shape of an octagon using physical and symbolic models. They make conjecture about the shape and relate it to the real world.

Students calculate the altitude of triangles.  In the web based lesson, students explore the interior distance from a given point in a polygon to its side.  They compute the sum of these lengths. Students read life...

In this similar figures worksheet, students identify the meaning of similar, corresponding sides, and congruent.  They use proportions to find the length of a missing side.  Students dilate given figures according to a scale...

This PowerPoint addresses fifth grade math concepts, focusing mostly on geometry. The interactive math review game is in a "Jeopardy" style format and enables students to revisit the topics in geometry such as polygons, quadrilaterals...

Students study geometric shapes and practice naming them properly. In this geometry lesson, students work in groups to give definitions of the vocabulary to each other in their own words. Students also visit a lower grade and teach...

In this math exam learning exercise, 8th graders review geometric and algebraic concept including angles, polygons, equations, factoring and addition and subtraction, quadrilaterals, trig and circles. They take a...

In this geometry worksheet, 10th graders review geometric concepts such as angles, polygons, quadrilaterals, trigonometry, and circles. They take a comprehensive exam covering topics on the Regents exam. There are 32 pages in this booklet.

Second graders identify the attributes of various shapes and estimate the weight of the objects. In this geometry lesson, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.

Students examine the rhombi or diamond shape and compare it to the square. Students are challenged to create as many flat rhombus shapes as possible and develop a definition for the rhombus shape in 20 minutes while working in teams of...

In this geometry worksheet, students find the area of squares, rectangles, and non traditional shapes. Students complete 5 problems on this worksheet. 

In this tessellating a hexagon worksheet, 10th graders complete 2 activities in creating a tessellation of a hexagon. They start off with the tessellation by the smallest pattern block and obtain other tessellations by replacing each two...

Using this worksheet, students practice identifying basic shapes, such as an oval, rectangle, triangle, and hexagon. This worksheet would be ideal for preschool or kindergarten students.

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

In this online math worksheet, high schoolers practice finding the area of 10 parallelograms given the length and width. When complete, students submit their answers and get instant feedback regarding their accuracy.

Students work in pairs, to make a square on the geoboards with a rubber band (or draw one on the dot paper). It can be any size and in any location and share their answers with the class.

Students practice calculating the perimeter of different sized rectangles. Individually, they identify the derivations of a function that can show the perimeter and determine how to minimize the perimeter within a fixed area. They use...

Students are introduced to the concept of perimeter. As a class, they listen to a lecture describing the derivations of a function that describes perimeter. They calculate the minimum perimeter of a rectangle and determine the numbers...

Students identify basic shapes (triangle, square, rectangle, circle), create shapes with different body parts, and create shapes at various levels (high, low)

First graders study the attributes of circles, squares, triangles and rectangles. They sort shapes that are the same and those that are different into groups.
