I am trying to help out my local elementary school with some math manipulatives.

These are examples of fractional elements and shapes however there are many different types available commercially. This school has NO MONEY so I wanted to help and thought ...hey I can cut these if I had the patterns. Of course they are easy enough to make in Corel but....

Has anyone already made a bunch of these types of manipulatives and can share the drawing files?
Also how would I color fill something like this number grid? I've never color filled so any assistance would be greatly appreciated.

Thanks
Pete

Most of those things can be made with the various flyout tools on the left tool bar.

How about using various colored acrylic so you don't have to worry about color fill.

The only color fill like paint I have done was on polished granite, simply wipe on and polish off the non-engraved areas. If you use finished wood I think something similar would work as long as your color did not attack the finish on the wood and perhaps dull it. I have seen something on a past post about color on plastic. I think they said to spray with color and then engrave the color off.
Hope this is of some help.

I've done the spray-with-paint-and-engrave-through thing and it works OK. One thing though: if you're using acrylic and acrylic car paint, a little bit of the paint ends up in your engraved bit...just enough to contaminate the colour a little bit if you're adding contrast by spraying with another colour from the back afterwards. I was using dark forest green, with gold as a secondary colour, which is possibly a bad combination, both added from the back. It still looked OK, but had a tinge of the first colour.

Just FYI

for the number grids I would use Rowmark or IPI plastic material to eliminate having to color fill. You could also use ADA solid core material to make the manipulatives. Just a quick thought.

...or use transparent and spray darkish colours on the back and engrave white on the front. That's cheap.
