Hey there…

I wanted to pass along **2 new applets** (ok, new to me) **for modelling fractions** – both on a number line and using an array model.

The first is a game, in which you have to select a fraction that is equal to or less than the fraction you’re given, with a **goal of moving all your sliders over to the far side of the screen** – in as few moves as possible. My best score was 12 moves… ðŸ™‚ Try out out by clicking here… **Here’s a game board:**

The second applet asks you to create **fractions equivalent to a given fraction on a number line**. You have to slice a box into sections and then shade the correct number of sections in order to get the point to align on the number line. I like this one because there are lots of ways to do it… Check it out by clicking the link here!

A screen shot of the game…

By the way… I’m thinking that the **rectangular array model**** is a far more powerful and visually meaninngful model than the “pie” model for representing fractions.** Those pieces are so hard to slice, to draw and to compare that they seem more trouble than they’re worth. I get the whole pizza reference and all, but right now I am leaning towards square pizzas for the sake of conceptual understanding.
