Since you were a baby, you’ve been involved in measurement.
Your parents wanted to know if your crib, and changing table, and other stuff would fit in the space.
Your height, feet, and even head was measured.
Now you aren’t a baby and you can measure yourself!
As you’ve gotten older, you’ve gotten
taller and wider.
Height and width are important measures for lots of things.
Beds… boards… buildings…
A unit of measure can be anything… like your shoe or your pencil.
These shoes, end to end, are two pencils long.
Usually, people like to use inches, feet, centimeters, and meters so we all know what we are talking about.
Area is the number of square units to cover a surface.
If each chocolate takes a space of 1 inch by 1 inch, the area of this box of chocolates is…
6 inches
4 inches
6" x 4" = 24 square inches.
Which happens to be the number of chocolates in the box. 6 inches
4 inches
Was the number of chocolates in the box.
6 inches
4 inches
Area = Length x Width
This football field is 100 yards long and 50 yards wide so it is…
5,000 square feet (not your feet, the 12 inch type of foot).
So, you could take 5,000 12" x 12" square pieces of colored paper and make artwork to view from an airplane!
Perimeter is the distance around a closed, flat shape. Add the length of each side.
When you run around the football field at PE, you are running 100 yards + 50 yards + 100 yards + 50 yards or…
300 yards!
Perimeter the length around the area. So, when you run, you run each side of the 100 yard by 50 yard field or 300 yards total!
300 yards isn’t that much!
There are 1760 yards in a mile so you haven’t even run 1/5 of a mile!
Review!
Area is…
6 inches
4 inches
Area is length x width
6 inches
4 inches
Perimeter is …
Perimeter is the length of each side added together.
Now, go recarpet your room!
Carpet can be $3 square foot (check the ads) and your room is how many square feet? The cost is?
Maybe you need to check “help wanted” first!
