Students make dog collages using triangles and rectangles. In this collage lesson, students use cut-out triangles and rectangles to make a dog collage after looking examples of Keith Haring's work and listening to Emma Dodd's, Dog's...

Students learn the basic definitions of a quadrilateral, parallelogram, rectangle and square and explain the relationship/classification process between them.

In this area activity, students commence solving for area of squares and rectangles, and continue to parallelograms and triangles, and continue again to rhombi and trapezoids and finish with circles, polygons, and shaded...

Students review basic shapes, such as circles, squares, triangles, and rectangles, find objects in those shapes in classroom, watch Clifford's Fun with Shapes video, practice reproducing four shapes, and rotate through four classroom...

Get started with area calculations using a simple shapes activity which could serve to introduce kids to this formula and the concept of units. They partition rectangles into columns and rows to determine the area based on the resulting...

Practice makes perfect! Learners estimate the least squares fit line for a set of data. They understand error involved in least squares fit lines, and solve application problems using least square fit lines.

Four triangles are depicted for learners to construct on a geoboard. They compute and compare the areas, and so meet one of the sixth grade Common Core standards for geometry. Note that the set of triangles does not include a right...

In this perimeter and area worksheet, students review the steps to find perimeter and area. Students then use grid paper to draw the figures described in 6 questions. Students note the perimeter and area of shapes as well.

Introduce the names and properties of basic 2-D shapes. Images and defining features of the circle, rectangle, triangle, and square are shown. Each image is colorful and includes a happy, smiling face, perfect for younger learners.

Discover the difference between standard and non-standard units of measure with your class. They differentiate between rectangles and squares, read a book, measure a peer's height. They then discuss  measurement methods, make...

Bring shapes onto the pitching mound! There are two diagrams here depicting a basketball court and a baseball field. Learners identify the shapes they recognize on each. They get a little guidance for the first one, but you should note...

This resource guides young geometers to create new polygons from others of equal area, compare an image to its reflection and find errors, conduct repeated reflections, map translations, and determine center of rotation. No solutions are...

There's a reason this worksheet is done in groups! Tricky word problems give geometry scholars a challenge as they use prior knowledge about shapes to find the area and perimeter given a few measurements. Students will enjoy discovering...

Young scholars find the area and perimeter of rectangular figures. They use this information to find patterns and discover relationships between area and perimeter. Students apply and explain formulas relating to perimeter, area, and...

In this math worksheet, students find the areas for the shapes. They apply the appropriate formula for each shape that is drawn and in the word problems.

Five pages for geometry practice relating to symmetry provide mathematicians with exercises on transformations and symmetry, properties of isometries, compositions of transformations, tessellations with regular polygons, and other...

In this volume worksheet, students recognize three-dimensional figures, identify the proper volume formula, and then solve the equation by inserting information from a diagram into the formula. Students solve six equations.

Use this lengths of horizontal and vertical line segments practice activity to have learners sharpen their problem solving skills as they solve six story problems.

Build on your learners' previous knowledge of geometric shapes and symmetrical figures. Then set them out to take photos of geometric shapes on campus. They assess whether the photos contain symmetry or not. 

Young learners listen to the story book The Greedy Triangle as the teacher introduces new polygon shapes. They use geometric stencils to trace a quadrilateral, a pentagon, a hexagon, and an octogon onto a foldable notepad....

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...

In this basic shapes activity, students view labeled pictures of a circle, square, triangle, rectangle and oval. They are not asked to do anything with these shapes.

Learners divide a poster board so everyone gets the same amount of area to decorate. Youngsters talk about the different ways to divide a rectangle. They measure their lines to make sure that each piece is equal and then decorate their...

This geometric pattern will appeal to learners' artistic sides as they color various shapes based on a guide: they color circles blue, triangles red, squares green, and rectangles yellow. What does this finished design remind scholars...
