First, highlight (or Select) the area for copying using the outline box tools.

Next, copy the selection to the computer's copyboard by clicking on Edit, the word next to File at the top of the screen, then clicking Copy from the menu that drops down. There is no apparent effect of this click but in fact the selected area is now stored on the computer's "invisible" copyboard.

Paste the stored copy back to the screen from the copyboard by clicking on Edit again and this time clicking Paste from the drop down menu. The pasted copy will always appear at the top left corner of the PAINT screen, usually to a chorus of "Oohs" and "Aahs" from the children.
Now use the mouse to drag the new copy and arrange it at any location on the screen.

Repeat the pasting as many times as you wish. The original copy remains on the copyboard until it's replaced by something else through a new COPY command, so don't stop pasting until the monitor screen is full of copies!

A STRONG RECOMMENDATION at this stage is to save your work "early and often" as a hedge against accidental, messy copying or further different inspirations.

Remember to keep the selection outline as tight to the image as possible because any surrounding background area copied will interfere with pasting.
Graphics (1), (2) and (3) describe this pitfall to avoid.

For a first exercise copy and paste from just one to make a screen full of boxes.

Color them all. Color the background. Maybe color one of them a different shade - just for a giggle. Stand back and admire your work. Print it if you wish.

CAN MATH

Using the ellipse and straight line tools the instructor draws a single can and saves the drawing as a file. Each child opens the file and copies and pastes the can image, making a row across the screen.
Then with the letters and numbers tool each child types a bunch of lower case o's separated by spaces.
The assignment is to make the content of each can match given values by dragging the corresponding number of o's into it. Color the contents to make them the eatables of your choice: cherries, corn, little green apples, blueberries, etc.
Extend this activity by having the children exchange places and fill in the top half of each can with the numeral value of its contents and ask a friend to drag the corresponding number of o's into the bottom half. Of course, when everyone has finished, we take our usual stroll around the lab to admire each other's efforts.
This activity may encourage participation in the Thanksgiving food collection drive!

DOMINOS VARIATION

Using the box (rectangle) and the straight-line tools draw one "domino" outline, then copy and paste to make a row of dominos across the top of the screen.
Below this row use the writing (A) tool to make a bunch of lower case o's, separated by spaces, across the screen.
Now drag and drop the zeros into the boxes to make some dominos of any denomination you wish.
An alternative method is to use numerals instead of the domino spots, but either way we can show all of the different ways a total of FOUR can be represented.

Don't stop with numbers! Have some fun drawing, drawing and coloring anything you can think of! Make rows or screens full of snowmen, hearts, shamrocks, Easter eggs, apples, trees, dreidels, and so on.

Around Halloween try making.....

or with even more pasting and coloring make .....

The picture above shows that the fastest way to copy when you are going for quantity is - outline, copy and paste by the rowful!
