Students find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped box...

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 participate in a series of challenging math lessons designed to engage their critical thinking skills. In these real-world problem solving lessons, student solve symmetry and repeated pattern problems, make lists/tables to...

Students engage their critical thinking skills to solve challenging math problems. In these problem solving lessons, student work with tessellations, weights/measurement, reasoning, surface area, geometric shapes, and algebraic procedures.

In this identifying transformations worksheet, 3rd graders look at three figures and choose reflected, rotated or translated to indicate how it has been transformed.

In this faces and vertices instructional activity, students determine which figures in pairs have more or less faces and vertices and name the figures. A reference web site is given for additional activities.

In this geometry activity, students look at a set of figures and determine the amount of faces, vertices and edges of each, then name each figure. A reference web site is given for additional activities.

For this area worksheet, students calculate the area of figures and determine the length of x. A reference web site is given for additional activities.

In this area and perimeter worksheet, students compare area and perimeter of pairs of figures, determining which has either the greatest area or perimeter. A reference web site is given for additional activities. 

For this perimeter worksheet, students calculate the perimeter and find given values of 6 figures. A reference web site is given for additional activities.

In this angles worksheet, students measure angles with a protractor and figure out if it is acute, right, obtuse, or straight. Students complete 6 problems.

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

Learners create a glossary of geometric terms while exploring tangram manipulatives.

In this side lengths worksheet, students determine the value of x in 4 pairs of shapes. A reference web site is given for additional activities.

Learners cut an index card to create three similar right triangles and explore the congruencies and proportions that exist. They investigate the properties of lines and concepts of congruency, similarity, tangency and symmetry of...

Students apply what they have learned, from Eight Hands Round a Patchwork Alphabet, about how quilt blocks got their names by constructing and naming a quilt block pattern of their own using pattern blocks and pattern block paper.

In this math worksheet, students study the geometric shape of the rectangle by tracing 10 shapes and coloring them different colors.

Students investigate properties of circles. In this geometry lesson plan, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

Double the dimensions, quadruple the surface area. Pairs build similar prisms and compare the ratios of their surface areas and volumes to the ratio of the heights. Given two similar cones, partners determine the ratios of the lateral...

Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...

Use your pupils' sense of curiosity to explore the Parallelogram Law. Here is an activity that outlines a complete lesson from beginning to end, allowing pupils to follow a conjecture through to the proof stage.

It is easy to find the area of a triangle where the base and the height are given. But in this resource, it is up to your geometers to identify the base and height of the triangle. In fact, your pupils will learn that there are three...

The class braids irrational numbers, Pythagoras, and perimeter together. The mini-assessment requires scholars to use irrational numbers and the Pythagorean Theorem to find perimeters of rugs. The rugs are rectangular, triangular,...

Stop and drop what is in your hand! Pupils investigate how form effects drag in the 12th part of a 22-part unit on aviation. Groups create equally weighted objects and determine which one falls the fastest by collecting data.
