Finding the Perimeter & Area The perimeter is the distance around the outside of the shape.

The area is the amount of square units to fill a shape.

AREA


I can understand that one way to measure plane shapes

is by the area they have.

I can cover a plane shape with square units to measure

its area.

I can understand that a "unit square" is a square with side lengths of 1 unit and it is used to measure

the area of plane shapes.


I can measure areas by counting unit squares (square cm, square

m, square in, square ft.).

I can understand area by thinking about multiplication

and addition.

I can find the area of a rectangle using square tiles and also by multiplying the

two side lengths.


I can find the area of a shape by breaking it down into smaller shapes and then adding those areas to find

the total area.

I can solve real world problems about area using

multiplication.

I can use models to show that the area of a rectangle can be found by using the distributive property (side lengths a and b+c is the sum

of a x b and a x c).


I can solve real world math problems using what I know about how to find the perimeter of shapes.

I can understand perimeter.

The Distributive Property & Area

When you break a rectangle into two smaller rectangles, the area of the large rectangle is

equal to the sum of the area of the two small rectangles.

You can use the ____________________________ property to break apart the facts and then find the product.

I can use models to show that the area of a rectangle can be found by using the

distributive property (side lengths a and b+c is the sum of a x b

and a x c).


_____________________________

Write the multiplication fact

that can be used to find the area. Solve the problem to find

the area.

Write the multiplication facts that show the area of the two smaller rectangles.

fact #1 _____________________

fact # 2 _____________________

You can find the area of the larger rectangle by adding the areas of the two

smaller rectangles..

_________________________ Fill in the missing numbers to complete the equation.

16 = 4 x (3 + 1) = (______ x 3) + (4 x ____)

Write the equation that shows the picture.


Problem Solving
