Several practice exercises suitable for any geometry class working on transformation, symmetry, and tessellation -- especially visual representations of image translation, rotation, and reflection, symmetry, tessellations and tangrams --...

This resource was written for the younger math learner, but finding the volume of an irregular solid is also a problem for algebra and geometry learners. Based on Archimedes’ Principle, one can calculate the volume of a stone by...

Students will examine solids to determine which has the least surface area. They will also understand the use of units, square units, and cubic units. There is also the teaching and application of geometry formulas to perform calculations.

Students explore Mandalas. They observe a PowerPoint presentation explaining the history of Mandalas and the Aztecs of Mexico. Students discover the connections between geometry, medicine, and ancient history. They describe the geometric...

Students work to find and reinforce concepts related to lines and angles. They identify the characteristics of shapes that have one, two, and three dimensions. The students also work on definitions related to the geometry of shapes.

Third graders engage in an enrichment lesson exploring the concepts of area and perimeter. They construct new pentominoes that are 3 times the size of normal ones and then identify the area and perimeter measurements. They then create a...

Students research flag designs and their geometric configurations. They design their own fraction flag and utilize the concepts of measurement, geometry and fractions to their designs. Each student attaches a craft stick or short dowel...

Young scholars compare and discuss characteristics and properties of 2- and 3-dimensional shapes. They construct 3-dimensional paper star figures, imaginatively customizing them with art tools and craft materials. Students analyze their...

In this geometry worksheet, pupils solve 5 word problems. Each of the problems involves finding one side of a right triangle. Story problems relate the Pythagorean Theorem to building ramps, shadows, and the length of a banner.

Use this geometry review worksheet to have learners complete nine problems involving transformations, area, volume, and unit conversions. They answer one multiple choice question on estimating lengths.

Geometry.... sweet! Using sugar cubes, learners build rectangular prisms of different sizes and shapes. They glue them together and assess volume. Then they color the outer sides to visualize and compute surface area. To make a visceral...

Here is an engaging geometry lesson plan which has students identify the properties of shapes and cut shapes out of magazines. They make cookies using cookie cutters in various shapes.

Students explore the Pythagoras theorem. In this geometry activity, students make right triangles and identify the parts of the triangle. Students complete measurements of the sides of the triangle.

Youngsters review different geometric figures and shapes. In this geometry instructional activity, pupils use formulas to calculate area, perimeter, circumference and volume of geometric shapes. They calculate the surface area also.

Students investigate the relationship between vectors and motion. For this geometry lesson, students create a system that exemplifies the principles of motion. They solve for the acceleration, velocity and displacement.

Learners identify and apply properties of triangles. In this geometry lesson, students define equilateral triangles by sides and angles. They build cardboard triangles as they study properties of triangles.

Young scholars sort through pictures of food to create patterns as they pertain to geometry. In this geometric patterns instructional activity, students relate to food as concrete objects that represent geometric patterns....

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...

Young mathematicians rotate, flip, and sort their way to an understanding of the different attributes of geometric figures. Using transparent yellow and blue shapes, children try to match congruent figures together...

Where do the coordinates lead? As children brainstorm ways to find the location of different buildings, they learn about coordinate points and how to use them to locate areas on a grid or map. They practice using ordered pairs by playing...

A triangle rests in quadrant two, from which your class members must draw reflections, both over x=2 and x=-2. This focused exercise strengthens students' skills when it comes to reflection on the coordinate plane.

Learners examine the properties of quadrilaterals from the point of view of rigid motion. Different types of quadrilaterals are characterized by their symmetries, so learners explore the symmetries of a described quadrilateral to...

Math and science come together in this cross-curricular astronomy lesson plan on planetary motion. Starting off with a hands-on activity that engages the class in exploring the geometry of circles and ellipses, this lesson...

What does slope have to do with lines? Pupils work with lines and determine the slope of the lines informally and with the slope formula. Groups use their knowledge to calculate the slopes of parallel and perpendicular lines. They also...
