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).

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.
