You can access all of the games on Legends of Learning for free, forever, with a teacher account. Use standard units of measure (square cm, square m, square in, square ft) to solve a problem.Ī preview of each game in the learning objective is found below. Prove that multiplying length and width will give the same area as counting all the individual tiles within the rectangle. Length and width are relative and can be interchanged. Use manipulatives and models to count the area of a rectangle with unit squares.įind the length and width of a rectangle using tile square units. Cover a shape completely with tiles and count to find the area. Solved examples to find the area of a rectangle when length and breadth are given. Note: Sometimes, base and height are used instead of length and width. The area, A, of a rectangle is the product of its length, l, and width, w. The grey space is the area of the rectangle in the diagram below. The number of square units it takes to completely occupy a shape is its area. So when we multiply its length and breadth we get the area of the rectangle. The area of a rectangle is the space contained within its perimeter. Explain to your students that it is the space inside a shape.

Ask your students if they know what the word area means.
#Finding the area of a rectangle how to
The area is measured by the number of square units that fully occupy a space without any gaps. (5 minutes) Tell your students that they will be learning how to find the area of a rectangle.

Using the length and width you just measured, plug them into the formula to solve for the perimeter. Plug in the variables and solve the equation. In the above example, the length is 5 cm and the width is 2 cm. A square with a side length of 1 unit is a square unit. Using a ruler, measure each side of the rectangle to determine the length and the width. The area is the entire space without gaps inside the border of the figure. The area is the amount of space a 2-dimensional figure occupies. Scroll down for a preview of this learning objective’s games and the concepts. This learning objective directly references 3.MD.C.7.a as written in the common core national math standards. X Research source In the formula for area (A), l is the length and w is the width of the rectangle. The Prove Area Of A Rectangle Using Tiling l earning objective - based on CCSS and state standards - delivers improved student engagement and academic performance in your classroom, as demonstrated by research. Write down the formula for the area of a rectangle, A l x w.
#Finding the area of a rectangle series
In this series of games, your students will learn to 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.
