Students choose a square of any size and use yarn to show that all 4 sides are the same. They sort the traffic sign cards into groups of squares and non-squares. Also they make a square using Q-tips; tell how you know it is a square.

Young scholars explore measurements and geometric formulas. In this geometry lesson, students investigate pi as it relates to geometry. They collect data and use a chart to organize the data.

Second graders explore fractions with a worksheet and marbles. In this fraction lesson, 2nd graders recognize the fractional parts of a shape pictured and find equal fractions.

Young scholars study polygons. In this math instructional activity, students play a game in which they learn the classification system for polygons. Young scholars identify the properties of quadrilaterals.

Sixth graders explore characteristics of similar objects. Using attribute blocks, they explore the ratios of the perimeter, area and side length in similar shapes. They calculate and compare the area of shapes.

Students measure planes and solids. In this geometry instructional activity, students find the area and perimeter of different polygons.They complete a word puzzle to review their vocabulary words.

Students calculate the surface area and volume of shapes. In this geometry lesson, students create different scales and calculate the volume and area for each shape. They compare and contrast between the different scales and shapes.

Learners calculate the area and perimeter of different shapes. In this geometry instructional activity, students name the different polygons based on their number of sides. They use the correct formula for each shape to calculate the...

Students find the surface area of cones. In this geometry lesson, students calculate the dimensions of each three-dimensional shape and use the correct formula to solve the problem. They relate concepts of cones to the real world.

In this geometry activity, 2nd graders review how to determine which piece would complete the geometric shape that is pictured. They circle whether it was a flip or a slide to move the piece into position. They draw or write to explain...

Students predict the shape of a geometric figure in 3D. In this geometry lesson, students construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive...

Sixth graders explore geometry by utilizing colored cubes in class. In this volume lesson, 6th graders identify the different shapes they can create using their colored cubes and identify the formula for finding volume. Students create...

Tenth graders predict the shape of a geometric figure in 3D. In this geometry lesson, 10th graders construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive...

In this geometry worksheet, students color the pictures of objects that are shaped like squares. They choose between 11 pictures of items such as a heart, a window frame, a computer, and a coin.

For this lines and planes worksheet, students answer eight true and false questions telling if two line segments are parallel or in the same plane. Students tell the line on the intersection of two lines and name the plane the lines are on.

In this solids instructional activity, 10th graders solve and complete 10 different word problems that include determining the volume and surface area of various solids. First, they determine the surface area of a cube as described....

In this math applications worksheet, students solve 6 varied problems that include estimation, money, basic operations, pictographs and geometry.

Second graders explore the features of triangles and quadrilaterals. In this lesson plan on triangles and quadrilaterals, 2nd graders rotate with their group to five different activities all exploring a different aspect of geometry.

Students compute the surface area of 3 geometric solids to determine the shape of package that would require the least amount of paper to wrap. In this geometry instructional activity, students work on a two-question assessment embedded...

Students construct the circumcenter of a triangle. In this constructing the circumcenter of a triangle lesson, students construct a triangle using Cabri Jr. Students draw perpendicular bisectors of the sides of the triangle. Students...

Second graders make, name, and describe, using their own language and the language of geometry, everyday shapes and objects. They create and discuss geometric patterns which repeat (show translation), or which have rotational or...

Students examine a selection of shapes and identify which shapes tessellate and why. They design and make a pattern which involves translation, reflection, or rotation. Students describe the features of 2-dimensional and 3-dimensional...

Students examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

In this geometry worksheet, students solve 6 problems in which an angle is analyzed. From 5 choices, students circle the correct math symbol that names the angle. There are no examples or explanations for the symbols, which would be...
