Color benchmark fractions8/28/2023 We can think outside the box and we might change our whole to be two hexagons or even three hexagons. But we want to be able to use these blocks to help kids create different fractional parts. Sometimes, we think that pattern blocks could be limiting because we might only see the traditional construction of a hexagon as the whole, a trapezoid as a half, a rhombus as a third, and then a triangle as a sixth. It’s nice to have kids use pattern blocks in a way that lets them explore or come up with different ways to create equivalent fractions. Today, we’re going to focus on using pattern blocks as a way of showing equivalent fractions, showing different names for fractions, and even being able to compare different fractions. This is really great for kids to see (as you can see in the video) that, as they lay the papers on top of each other, they can see how those pieces of paper change in size and how they can rename the fractional pieces they are working with. We cut whole sheets of colored paper or cardstock in half, and then in fourths, and then again in eighths, then sixteenths. Our area model paper was the topic of a Facebook Live video a while back, and it is another great manipulative option. Sometimes the fraction tiles can be limiting, however, because they do tell which fraction they are, so when you’re renaming fractions with different shapes or different sizes, you are stuck with whatever label it has (1/12 or 1/6) and you can’t change the whole. These tiles are especially great as a foundational manipulative because they’re labelled, so every tile tells you what fractional part it represents. This manipulative is easily thrown away when you’re done with it, and it’s easy to store in your Math Salad Bar.Īnother manipulative that helps kids starting to learn how to compare fractions or even find other equivalents or names for fractions are fraction tiles. This paper is nice to use while comparing or looking at fractions of different size because you can fold the patty paper or use colored pencils to color different sections of the paper in order to visualize another piece that might be the same size. Patty paper is just square paper, like the square translucent pieces of wax paper you might see between hamburger patties at the deli. One of my favorite manipulative to use with students is patty paper. When we create our flip book during our 21st Century Math Initiative training for grades 3-5, we look at the main manipulatives that might be used to help students see equivalence and we focus on helping teachers know which manipulative would be the best for kids to use as they’re starting to understand these different concepts. There are a variety of manipulatives that can be used for fractions.
