Framing Nature With
out nine saltine crackers on a plate, three to a row. With a ruler, measure the
height and width. Round off to the nearest inch. Multiply. How many square
inches of crackers do you have? Blob a little peanut butter and jelly on each
one. Eat! Drink a glass of milk with your _____ (fill in the blank) square

Don't you love nature? It's fun to
get outside and study it, up close and personal. Today, we'll combine nature
study with a little math measurement exercise for double the learning and fun.
Simply place a blank picture frame
onto a spot in your back yard, a park, a playground, a garden, the base of a
tree, or anywhere you'd like.
With a ruler, measure the height and width of the
inner rectangle of the frame. Round off to the nearest whole inch. Maybe you
have a 4" x 6" frame, or an 8" x 10" frame. Write down the two measurements on
a piece of scratch paper.
Now figure out how many "square
inches" that frame shows. All you do is multiply the height times the width. So
if you have a 4" x 6" frame, that's 4 x 6 = 24. That frame shows 24 square
inches of space. If you cut out 24 little pieces of paper, each of them 1 inch
tall and 1 inch wide, 24 of them would fit inside that frame.
How many square inches of nature
does your picture frame show?
Now look closely at the nature
within that frame, or use a magnifying glass. Write down on the scratch paper
all the things that you can see. Rocks? Pebbles? Dead leaves? A clump of grass
blades? Live leaves? Gnats? A cucumber beetle? Dark brown soil? Light tan soil?
A roly-poly bug?
See how much neat stuff you can find
in every square inch of nature?
