Window panes

Directions for WINDOW PANES ( due every Thursday):

1. Divide an index card into quarters.
2. place the term your are describing in the middle.
3. In the top left square describe the term using your own words.
4. In the top right square use the term in a sentence, a grammatically correct sentence.
5. In the bottom left square give an illustration of the term, anything you picture when you think of the term. An example would be drawing a ruler or calculator for the term "data". If you are not comfortable with drawing, you can create a multiple choice question for the term.
6. In the bottom right square give a synonym or antonym for the term. Any word that has a similar ( or opposite) meaning or use as the one you are working on.

Remember you must complete window panes for 20 of the terms listed, however, you must know what all of the terms mean.

I suggest that you do the 20 words that are the most difficult for you.

DON'T PUT THIS OFF UNTIL THE LAST MINUTE, THEY TAKE MORE TIME THAN YOU THINK.
