Rose Ball

Project taught by Dr. Eva Szillery at the Downtown Education Collaborative in Lewiston, ME.

The project was originally designed by:  Unknown

The "Rose Ball" requires a total of 60 squares of paper.

Five squares are used to create each rose; twelve roses are used to create the rose ball.

Direction for folding the rose ball modules:

Step 1:  Fold the paper in half to create a mountain fold.

Step 2:  Fold the paper in half in the other direction to create four congruent

squares with the crease lines.

Step 3:  Fold the top two corners in toward the center as shown below.

Step 4:  Fold the bottom edge up toward the center as shown below.

Step 5:  Turn the paper over as shown below.

Step 6:  Fold the bottom edge up toward the crease that separates the

triangle from the rectangular base.  This will create a crease that runs

horizontally across the center of the rectangular base of this shape.

Step 7:  Fold the lower corner up to create a 30-60-90 triangle.  The 90

degree angle should line up with the crease you formed across the

rectangle in the previous step.

Step 8a:  Fold the right edge of the triangle across as shown below.

Step 8b:  Unfold, and notice the diagonal crease that bisects the left

small triangle.  Fold it closed once you have confirmed that you have

the correct fold.

Step 9:  Notice the right trapezoid on the right side of the shape above.

In this step, you will fold this trapezoid behind the triangle as shown below.

The shape above is a "finished" unit.  You will need five of these to make

a rose; twelve roses to make the rose ball.

DIRECTIONS FOR ASSEMBLY:

Step 1:  Line up two units as shown below.

Step 2:  Notice the small triangular tab on the right side of the pentagon.

This tab will wrap around the right trapezoid of the unit on the right.

Step 3:  Open the shape to the left.

Step 4:  Slide the two pieces together and wrap the tab from the left shape

around the trapezoid of the right shape.

Step 5:  Apply a small piece of tape to this side of the shape where the

two pentagons meet.  This is the back side of the rose, so the tape will

not show later!

Step 6:  Turn over as shown below.

Step 7:  Pull the top edge up to reveal a smaller rectangular piece underneath.

Step 8:  Lift the top layers of that smaller rectangular piece up.

Step 9:  Tuck the larger rectangular piece into the open fold of the smaller

rectangular piece as shown below.

Step 10:  Turn the shape back over, then line up the third piece.  You will

use all of the same steps as shown in assembly steps 1-9 to attach this

piece, and then the remaining pieces.

Once you have attached five pieces, you will have a "rose" as shown below:
