Grab some paper and something to write with.
Start by having your child write a capital A.
When completing the middle of the A, have your child extend the line through the A on both sides.
Starting at either the left or right side of the extended line, draw a line to the bottom of the opposite leg.
Draw a line from the remaining end of the extended line to the bottom of the opposite leg.
As easy as that, a star made and...
Before you know it, you'll have a sheet full of stars.
And, it all started with an A.
