![]() If students are trying to compare or order fractions with. For example, here’s an area model of the fraction 3/5: How is this helpful Let’s explore: Using an Area Model to Compare Fractions with Unlike Denominators. An easy way to do this is to use graph paper. At this time, you want to encourage discussions about which wholes encourage more precise drawings for modeling specific denominators.įor example: Students are not as precise at drawing thirds in a circle as they are in a square.įor more information on representing fractions with an area model to encourage understanding of fractions, visit or read the article. An area model represents a fraction as a rectangle, divided into equal parts. We also want to eventually move students to drawing models of fractions. Students need experiences with determining, creating and identifying fractions in various shapes to know that fractions can be found anywhere in the real world. Fractions can be found in more shapes than just squares or circles. The denominator 8 represents the total number of equal pieces that make up the whole.ĥ. The numerator 3 represents the number of equal pieces shaded. The picture below models 3/8 of the whole as shaded. At this time students need to be able to represent it in fraction language and numerically as a fraction. ![]() The numerator represents the number of pieces being discussed or focused on and the denominator represents the amount of total equal pieces in the whole. The below shape is cut into sixths because there are six equal pieces that make up the whole.Ĥ. You want to encourage students to identify shapes broken into each fractional amount. This occurred in 2nd grade using the language of fractions without using numbers to represent. Name the equal parts found in the whole as halves, thirds, fourths, sixths and eighths. We want students to understand that the below shape is also cut into fourths because they cover the same amount of space or are the same area.ģ. The below shapes are common ways that students break squares into fourths because they are the same area and the same shape. From there – they can prove they are equal by cutting the parts up and comparing the size of the pieces. A great way to explore this is give students square post-it notes and have them find all the fourths they possibly can. Understand that the parts of the whole can be equal without having the same shapes within the whole. Students need to understand that this is not demonstrating fourths because they are not equal parts.Ģ. Area Map: A form of geospatial visualization, area maps are used to show specific values set over a map of a country, state, county. Students need to understand when it comes to modeling fractions with an area model, that the parts need to be equal or cover the same amount of space.įor example: A common misconception is shown below. The Top 5 Things Students in 3rd Grade need to understand about modeling fractions with an area model are:ġ. ![]() In 3rd grade students are expected to, “Understand a fraction as the quantity formed by 1 part when a whole is partitioned into equal parts.” The best way for students to develop this understanding is by putting fractions into real world context and create area models. ![]()
