Cubic Units and Sonobe Cube Construction

Transforming Ninja Star with 8 points

This 8 point ninja star (or 8 sided ninja star) is a complex shuriken because it can also transform into a round blade or frisbee. Again, be careful where you throw it because the points can be sharp.

Sonobe Cube

Exploring volume is one of the most interesting and useful exercises in mathematics. We measure volume in cubic units so it is only logical to teach the children how to build cubes.

In the mid 1960s, Mitsunobu Sonobe from Japan, created the design now know as the Sonobe Cube. The children were taught how to create six congruent (identical) units from a square piece of paper. It is best to use two each of three different colored paper. Please see the attached pdf for folding instructions.

The learning objectives are:

Origami Octogonal Ninja Star

 

Shuriken ( literally "hand hidden blade") is a traditional Japanese concealed weapon that was used for throwing, and sometimes stabbing. They are small, sharpened, hand-held blades made from a variety of everyday items, such as needles, nails, and knives, as well as coins, washers, and other flat plates of metal.

We of course are making these so called "Ninja Stars" out of paper to be "somewhat" safe. It will fly like a small frisbee.

 

The learning objectives are:

Triangular and Tetrahedral Numbers
