Slices

I created four worksheets of sorts, each one consisting of a title and images of a dozen circles. Each circle is divided pizza-like into slices, as in the example above. You can download them together, or separately: Angles, Fractions, Time, and 100. (The latter, of course, suitable to discuss percents, decimals, and money.)

Some interesting curriculum could be developed using these images. Here is one example, which I'm told was very successful with seventh graders: Angles Lessons. I combined it with lessons from Geometry Labs into a middle school unit on angles (including teacher notes).

One basic question that can be explored using these images is in the form "what is `1/5` of 100?", which makes it easier to answer "what is `3/5` of 100?"

Here are some notes on using two worksheets for elementary school lessons on time and money.

If I do more with the worksheets, I'll post it here and announce it on my blog.

If you use the worksheets, send me your creations, and I may post them here! (Crediting you, of course.)

Here's the GeoGebra sliced-circle maker I used. Create your own worksheets, and send me a copy!
