Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Step 1: the Tracing
OK know your design, then draw it on the cardboard and another right next to it. Another more efficient way is make a oragami Shuriken and trace that. What ever works for you.
Then go on to Step 2
Step 2: Step 3: Cut and Tape
OK then you cut the two shuriken shapes from the cardboard.
After, tape them together with packing tape, make an X in between the points.(in the picture, the X means the tape) After u do that a few times, smear your finger on the edge of it to make it shaped.
GO ON TO STEP 3
Step 3: Step 3: More Taping
Yea, Yea, more tapeing, but all you do is, tape it like before, over the masking tape, But do it a lot.
see photo 2
(the grey is the tape, brown is still cardboard)
After, tape the corners. Its a little different than just "mummifing" it. This time you put the tape DIAGNAL on the corner, then wrap it like present.
See photo 1
The just tape it over the wrapping lines.
Step 4: Last Step
If you want it to be heavyer, just repeat step 3. Tape it up some more, BUT I MUST WARN YOU IF YOU PUT TOO MUCH IT WILL TURN INTO A SQUARE WITH POINTS< so dont put too much tape.
HAVE FUN, AND BE SAFE!
