IT'S A BIRD,
IT'S A PLANE,
IT'S SUPERFROG!
LEAPS RULERS IN A SINGLE BOUND!

MATH APPLICATIONS:

1. Measurement & Estimation
2. Problem solving - accurate folding for leaping ability
3. Geometry - reinforces & illustrates:
   
   
   1. various angles
   2. various triangles
   3. various quadrillaterals
   4. congruent triangles & similar triangles
   5. a diagonal and the sides of a parallelogram form two congruent triangles
   6. diagonals of a parallelogram bisect each other
   7. rotation & symmetry
   8. CPCTC: corresponding parts of congruent triangles are congruent
   9. distance between two given parallel lines is a constant
   10. etc, etc, etc
   
   
4. Cooperative learning
5. Hands-on experience
6. Activity to collect data to calculate median fit line **

SCIENCE APPLICATIONS:

1. Measurement & Estimation
2. Problem solving
3. Machines - rear legs resemble wedge design & performs like a spring mechanism
4. Cooperative learning
5. Hands-on experience
6. Activity to collect data
7. Introduction to frog unit

MATERIALS: 3x5 inch index cards

DIRECTIONS:

1. Hold card so that the lined side is facing you.
2. Fold B to AD to form right triangle & unfold. 3. Fold A to BC to form right triangle & unfold.
4. Push in at E where folds intersect. **
5. Bring AB to coincide with FG while at the same time bending AF & BG. A pentagon will be formed. ***
6. Fold B to E and A to E. Two small congruent triangles are now on the top of the pentagon and will be the front legs of the frog.
7. Fold GC so that G meets H. Fold FD so that F meets H.
8. Bend DC away from you and then IJ towards H the same amount.
9. Voila! You have made your Superfrog. Decorate it with eyes and mouth.
