Some items keep their shape no matter what happens! Have your kindergarten class choose which items would stay the same if they were bent, stretched, or squashed. The last activity prompts kids to see what happens when they stretch a...

Explore how resizing an object affects its area. The set of lessons challenges young mathematicians to design a mascot for electronic devices. These designs undergo resizing to determine how scale factors of dilation affect area.

Boxing takes on a whole new meaning! The second installment of the three-part series has groups create lidless boxes from construction paper that can hold the most rice. After testing out their constructions, they build a new box....

Students find two dimensional shapes in three dimensional figures. They determine the shapes that make up the faces of three dimensional figures of common classroom objects such as crayon boxes.

Second graders identify and describe basic geometric solids. Working as a class, 2nd graders describe geometric solids using the proper vocabulary and counting faces, bases, corners, and edges. In pairs, students use a computer drawing...

Students locate lines of symmetry in regular polygons and predict the number of lines of symmetry in an octagon. In three different polygons, they construct all lines of symmetry and after making their prediction about the octagon,...

Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

In this quadrilaterals and other polygons worksheet, students name various polygons and then decide if each polygon is a quadrilateral. Students also decide is certain polygons regular or irregular.

Students study geometric images and polyhedrons. In this geometry lesson, students complete several activities to learn about geometric shapes and classify polyhedrons from polygons. Students watch a video, complete a web-directed...

For this polygon worksheet, students determine whether a set of given polygons are irregular or regular. A reference web site is given for additional activities.

Young scholars create a scale model to a castle using the dimensions they were given. They calculate the surface areas and volumes of each section of their castle.

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 congruent figures worksheet, students analyze a geometric shape and choose from the answer box any figures that are congruent to that shape. There are 3 problems.

In this planes worksheet, students solve 5 multiple choice problems. Students determine which planes intersecting create a given line. Students determine which point is coplanar with three other ones.

Students solve word problems by using basic geometry. In this geometry lesson, students use geometric formulas to find the perimeter, area, and volume of objects. Students complete a worksheet.

Young scholars study mirror wells, which are similar to 3-D kalediscopes, but the end is cut off to enable you to look at patterns through them.

In this congruent figures worksheet, learners apply their math skills as they respond to 4 questions that require them to select shapes that are congruent to the 4 given shapes.

In this congruent shapes worksheet, students complete multiple choice questions for which shape is congruent to the one on the left. Students complete 4 problems total.

In this patterns worksheet, students find the missing number, shape, or letter needed for the patterns. Students complete 10 multiple choice questions.

For this solid figures worksheet, students learn to identify solid figures by their faces, edges, and vertices. Students solve six word problems about the solid figure characteristics.
