Topic One
This topic is to teach children how to find the area of a square and rectangle.
Children need to know how to read formulas for finding answers on mathematical problems.
All should know how to calculate these formulas.

Topic Two
The area of a square or a rectangle is found by multiplying the length by the height.
Area =lxh
Area = l x h

Now we can figure out how much it’s going to cost us to put a new rug in our house. We just have to figure out the square footage, and how much a square foot.

DETAILS
AREA OF A SQUARE IS EQUAL TO HEIGHT TIMES LENGTH.
AREA OF A RECTANGLE IS EQUAL TO HEIGHT TIMES LENGTH.

Real Life
If you have a trailer that measures 5 feet wide by 12 feet long, how much ply wood will you need to plank it?

What This Means
It is important for all children to be able to use formulas in real life situations.
• All students should memorize the formula for finding the area.
• All students should have had the opportunity to work out several problems.

SUMMARY
Children need plenty of examples to learn.
Children need to work in teams. Children need visuals. Children need real life situations to
be meaningful.
