Get third graders excited to work find area and perimeter of unit squares, rectangles, and irregular shapes. A 36-page packet comes with task cards, graphic organizers, practice worksheets, printables with squares, exit tickets, and word...

Third graders are challenged to draw their own rectangles given a specific area or perimeter. There are no examples of how each rectangle should look, so it is important for learners to persevere in finding a solution. There is more than...

Given a rectangle with specified dimensions, learners are prompted to create a new rectangle with the same perimeter, but a different area. This challenges third graders to think about perimeter and area in a new way. Each problem...

Given a rectangle with specified dimensions, third graders are prompted to create a new rectangle with the same area, but a different perimeter. This challenges learners to think about perimeter and area in a new way. Use worksheet as a...

Third graders measure area by counting unit squares inside a rectangle.

Third graders find area by tiling a rectangle based on the given side lengths. This helps learners visualize and create the area of a figure. From here, they can count the total number of tiles inside the rectangle to find the answer.

Area is the amount of space that takes up the inside of a figure. To find the area of a rectangle, one must multiply the length by the width. Here, third graders are challenged to find the missing side length, given the area.

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on to learn the...

Learners calculate the perimeter of rectangles and squares. They imagine trying to build a fence around a yard or trying to determine how much paint they need to paint a room. They also develop formulas and procedures for determining the...

Who knew that a party is all about the area. Individuals draw out a patio on grid paper while planning to host a party. Using colored paper to represent the total area of the patio, learners cut out furnishings to add to the patio,...

Storm into a better understanding of geometry. Using a tornado as a backdrop, scholars practice their skills finding perimeters and areas of rectangles. Learners apply their knowledge of the Pythagorean Theorem to find missing sides of...

Looking at area with a hole. Using algebraic expressions as dimensions, learners see how to calculate the area of a rectangle that contains a square hole. The instructional video shows how to create a single expression for the area of...

Plan a dinner party. Using a book by Marilyn Burns as a context, pupils learn about the relationships between area and perimeter and surface area and volume. The hands-on activities have learners rearrange tables and cut up meatballs to...

Make the connections between area, tiling, and multiplication. A performance task and associated unit presents the concept of area and makes the connection to multiplication. Pupils work through three major sections of instruction that...

Firmly plant the concept of area into the classroom. A performance task dealing with area uses gardening as a context. The outline of a unit with activities keeps with the gardening theme and provides instructional support for teachers....

Apply polynomial multiplication to area. The short video in a large series shows the process of creating a polynomial formula for the area of a rectangle. Using the two expressions for the length and width of a rectangle, pupils see how...

All that matters is the tiles. Pupils use the interactive to investigate the relationship between area and perimeter using tiles. The interactive has an explore and a game mode to accommodate different steps in learning. The game mode...

Take a coordinated look at rectangles. The task asks pupils to plot the length and width of created triangles in the coordinate plane. Using their plots, scholars respond to questions about rectangles and their associated points on the...

Find the area as it slides. Pupils derive an equation to find the painted area of a section of a trapezoidal-shaped stage The section depends upon the sliding distance the edge of the painted section is from a vertex of the trapezoid....

What? The calculation of area is a linear distance? A short video shows how to use the areas of simple polygons to estimate the area under a graph. Pupils divide the area under a curve into figures to easier calculate the area. Given...
