Bunny Sliceform

Bunnies are an Easter tradition.  I love their pastel colors.  The bunnies presence really brighten a room. Sliceforms are my obsession; so what better way to combine my passion for both of them.

Here is the PDF file.  I used cardstock.

Here is the .Studio file.

 Separate the slices.  The rectangular slices should be ordered from longest to the shortest.
 Starting at the left hand side, slide the longest rectangle into the first left slot. Then slide the next shortest size. The middle piece is the shortest rectangle. The next two slices increase in size.  Above is a picture of what it should look like when all the rectangular slices are attached.
 Slide the bunny piece onto one side as shown above. 
 Turn the bunny over and repeat.
The bunnies are so cute.  They can fold flat for mailing.
Happy Easter!

A Tactile Paper Ruler

As a math teacher, I often find students having difficulty measuring with a ruler for a variety of reasons. The students don't know where to place the ruler because many plastic rulers have a quarter of an inch of plastic before the tick marks start or the students can't read the hash marks. This ruler that I created from glossy cardstock will help those students visually and tactilely see the different measurements.  The leading edge of the ruler begins the measurement.  There are three different size markings.  The inch marking is the longest slit, the half inch slit is a little smaller and the quarter inch slit is the smallest.  At the top of the ruler, there is a large notch at the inch mark and a smaller notch at the half inch mark. The ruler can be manipulated so that the student can fold up a portion of the ruler if needed to make sure a measurement is correct.

The ruler can be folded up and the slits can be turned upwards at the quarter inch and half inch marks.

Here is the PDF file.

Here is the .Studio file.  I used a glossy cardstock because regular cardstock will not cut out the numbers correctly.  The plasticized  surface of the glossy cardstock cuts the small numbers precisely. You will notice in the picture that there is a yellow and orange ruler that has their numbers not cut all the way through with the plain cardstock.

Disclaimer: If you produce this ruler, please ensure that the measurements of this ruler are correct with an actual ruler.  I cut this with my Silhouette and it is off by a hair. I think I might need to recalibrate my Silhouette but I am a little wary and feel the minute difference does not warrant changing the settings.

Super Pi Day Ball

Super Pi Day is coming!  3.14.15 is a once in a century event.
 Pi Ball with different diameters of Pi

In honor of Super Pi Day, I decided to make a sliceform which represents the values of pi.  I created the five circles with multiples of 3.14.    The diameters starting at the smallest circle is 3.14 cm, 6.28 cm, 9.42 cm, 12.57 cm and 15.71cm respectively. I then placed the diameter of each of the four smaller circles on the edge of the largest circle at its midpoint to create a slit so that this sliceform could be created.

Looking at it head on when the sliceform is a sphere, starting from the smallest circle and going inwards, you can visually see the increase in values of pi from 1 pi to 5 pi.

Laying the sliceform down, the center is the largest circle of 5 pi and the other circles are skewed closer to the edge.

I made a sphere sliceform here.  I love the visual differences of the two sliceforms.

Poor Pi Ball does not have as much structure as a regular sphere sliceform.  The slices are not at fixed intervals but at a multiple of pi.

Here is the PDF of the Pi Ball sliceform.  I used cardstock to create the model.

Here is the .Studio file.

Happy Super Pi Day!
