As you know, we have recently blogged about CPA, and the importance of bringing the concrete and pictorial (or, representational) back into our teaching as a bridge to the very abstract world of math.  We can't stress enough how much we see this missing from the curriculum used in the schools in our math initiatives. As teachers, we must find ways to get the concrete back into our teaching!

Fraction Tiles with Tray These fraction tiles are a great way to bring the concrete back into learning fraction concepts, and to provide both a visual and hands-on learning experience. With these color-coded tiles, students can manipulate parts of a whole to see how they relate to each other and use the tiles to perform simple math operations with fractions, decimals and percentages.

This website is great because you can choose grades prk-5 and what you want for your background, and what manipulative you want.

There are tabs on the left that say, "fractions," "decimals," and "percents."  When you click on one of those tabs, it expands the screen full of manipulative that you can drag and drop onto the work mat. Not to mention, this website has a massive amount of other math and ELA resources.  Definitely worth exploring!

This website gives you many choices of manipulatives to teach fractions.
