This task challenges students to find the area of different sections of a garden and the entire garden. With missing lengths and widths, the students are challenged to apply computation skills to finding missing measurements.

This task requires students to find the area and perimeter of a rectilinear figure and model their thinking through multiple equations. This task relates to the Common Core State Standards: 3.MD.C.7d, 3.MD.D.8, and 3.OA.D.8.

Related to standard AR.Math.Content.3.MD.C.7., this is a multisection lesson for the 3rd grade unit of study on area in relation to multiplication, complete with teacher notes.This lesson is designed to be taught with an 'I Do, We Do, You Do' format. Starting with an introduction slideshow, students will connect multiplication with previous concepts and skills such as repeated addition, skip counting, and equal groups. Then they will see a video and example problems which can be completed together as a class. Allow time for students to read and complete some of these example problems with a partner which will give time for questioning, addressing misunderstandings, and informal interventions. End the lesson with a preview of the next day's independent activity and an exit ticket using a quick image. 

In this unit, students learn to find areas of polygons by decomposing, rearranging, and composing shapes. They learn to understand and use the terms “base” and “height,” and find areas of parallelograms and triangles. Students approximate areas of non-polygonal regions by polygonal regions. They represent polyhedra with nets and find their surface areas.

Use tiles to represent variables and constants, learn how to represent and solve algebra problems. Solve equations, substitute in variable expressions, and expand and factor. Flip tiles, remove zero pairs, copy and arrange, and make your way toward a better understanding of algebra.

Student will watch the two video about area and perimeter. After they will construct their own pieces of each from graph paper. They must create their own animal within the graph paper. They will count the squares for the proper area and count along the outside for perimeter.

This is a lesson for learning about area and perimeter of rectangles.

This corresponds to "College and Career Ready" standard (3.MD.7a) -- Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths.
(I was not able to find that standard here.)

This is a hands-on guided lesson for relating area to factors. Students will model area of rectangles using Cheez-Its and define factors as the dimensions of the rectangles.

An interactive applet and associated web page showing how to find the area and perimeter of a square from the coordinates of its vertices. The square can be either parallel to the axes or rotated. The grid and coordinates can be turned on and off. The area and perimeter calculation can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appears on the screen to make handouts. The web page has a full description of the method for determining area and perimeter, a worked example and has links to other pages relating to coordinate geometry. Applet can be enlarged to full screen size for use with a classroom projector.

In this lesson, students in this lesson will learn about, connect, and apply the use of the area to a real-world problem—creating a planting guide for the garden. Students will determine the square footage of the garden and use this information, along with a planting chart to create their own plan. Background for instructors:Math in the REAL world: Area and square feetSquare foot gardening is one way that ensures a vegetable garden bed can thrive. It is used to ensure not too many plants of a specific variety are planted in a single area. Using the square foot model keeps plants properly spaced, providing a perfect real-world context to teach area, apply multiplication strategies, and have students work collaboratively. Most garden beds are 8 x 4 resulting in 32 square feet to work with. It is possible however to have beds of different sizes. While 32 square feet to work with is what is used in this lesson, the methods and chart can be used for any rectangular planting area.

An interactive applet and associated web page that demonstrate the area of a circle. A circle is shown with a point on the circumference that can be dragged to resize the circle. As the circle is resized, the radius and the area computation is shown changing in real time. The radius and formula can be hidden for class discussion. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate the area of an ellipse. The major and minor axes can be dragged and the area is continuously recalculated. The ellipse has a grid inside it so that students can estimate the area and compare the result to the calculated one. The web page has the formula for the area calculation. The web page also has links to other pages defining the various properties of an ellipse and to some ellipse constructions.
