In this lesson, we will learn:

- Square measure refers to the squared units that are used to measure area
- How to count the square measure of areas shown by unit square figures
- Comparing between metric units and squared metric units

**Square measure**refers to the**units**we use to measure**area**- A
**unit square**is a square with a measure of__1 unit__on each side - Units can be in
**metric units**(i.e. m^{2}, cm^{2}, mm^{2}) or other**customary units**(i.e. ft^{2}, in^{2}, yd^{2})

- Different
**dimensions**(1-dimensional or 2-dimensional) correspond to**geometric properties**of shapes (**perimeter**or**area**) as well as their units:

- The
**square measure**of**area**can be thought of as the number of__unit squares__that cover the 2D shape. You can count each unit square one by one to find the area. - If you have a
**rectangular**figure of unit squares, think of it as an array:

**Converting**between metric units: meters (m), centimeters (cm), millimeters (mm)

**Converting**between squared metric units: m^{2}, cm^{2}, mm^{2}

**Comparing different square measures: mm**^{2}, cm^{2}, m^{2}

Fill in the blanks for the proper unit for each object: mm^{2}, cm^{2}, or m^{2}.a)The classroom wall measures 15 ___.b)A sheet of lined paper measures 616 ___.c)One face on a die measures 144 ___. - 2.
**Calculate the area of a figure made of unit squares**

Calculate the area of each figure. Give the answer with the proper units for each unit square.a)b)c) - 3.
**Area of figures drawn on grid paper**

Using the centimeter grid paper, draw a rectangle figure with an area of:a)4 cm^{2}b)24 cm^{2} - 4.
**Convert between square units using conversion facts**

Convert the square units by using the conversion fact.a)If there are 10,000cm^{2}in 1m^{2}, how many cm^{2}are there in 6m^{2}?

10,000cm^{2}= 1m^{2}

_____ cm^{2}= 6m^{2}b)If there are 100mm^{2}in 1cm^{2}, how many cm^{2}are there in 800mm^{2}?

100mm^{2}= 1cm^{2}

800mm^{2}= __ cm^{2}
