Introduction

• These slides are to inform you how important it
  is for students to be able to read and use
  formulas.

3
Allow students to practice finding the area of
squares and rectangles.

• CUS

4
Topics of Discussion

• The two main ideas to teach are
• A. Formula for finding area of a
• Square.
• Formula for finding the area of a rectangle

5
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
Now we can figure out how much its 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.

• The area of a square or a rectangle is found by
  multiplying the length by the height.

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?

10
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.
