3. Cut the slots from the back edge of the wing halfway across. The slots are only cut to the midpoint of the wing. They are not cut all the way across. Since the wings are 3” wide this cut should be 1 ½” long. Calculating this measurement provides practice with fractions.

Make the Landing Gear:

1. Cut a piece of cardboard into a rectangle that is 3” wide by 5 ½” long. Make two of them. It would be possible to provide a pattern to be traced, but that eliminates the mathematics.

2. Place a mark 1” in from the edge along the bottom. It does not matter which side but should be along the short edge of the rectangle.

3. Draw a line all the way across the rectangle 2 ½” up from the bottom edge. This line is used twice.

4. Draw an angled line from the 1” mark to the end of the line at 2 ½” . Here again students draw along a straight edge.

5. Cut the angled line.

This should pose no problem.

6. Cut a slot from the straight edge along the line at the 2 ½” mark halfway across. Since the rectangle is 3” wide this cut should be 1 ½” long.
