What fraction is represented by the intersection of the two shaded areas? 6/12. Next, divide the unit square horizontally into fourths. To demonstrate this with an area model, begin by dividing the unit square vertically into thirds. Let's take a look at a multiplication problem: 2/3 x 3/4. What is the new fraction represented by the shaded area? 8/12. Prerequisites Students should already be familiar with modeling fractions by shading part of a rectangle (area model), simplifying fractions. Next, divide the area of the unit square into four horizontal rectangles (to demonstrate that you're multiplying both the numerator and denominator by 4). multiply two fractions together using an area model (including identifying problems where multiplication is required, e.g., finding 1 2 of 8 1 0 ). Shade in 2/3 of the area of the unit square. If we were to demonstrate 2/3 = 8/12 fact using an area model, first divide the area of the unit square into three rectangles. If your students are ready to be challenged with the symbolic form, you can explain: After various opportunities to experiment informally with fraction sticks and write down their observations, they will be ready to learn a more formal rule: when you multiply the numerator and denominator by the same non-zero number, you will obtain an equivalent fraction. They can choose a fraction, such as 2/3, and see what combinations of other fractions are equivalent, such as 8/12. Click on the image to view or download the PDF version. They also provide immense flexibility for students to work at their own pace. This enables students to clear their concepts of simple multiplication problems and then solve more complicated problems. This is a great time for students to experiment informally with fraction sticks. Free Shade It In Multiply Fractions With Area Models printable Math worksheets for 5th Grade students. The questions in the worksheets have a gradual increase in the level of difficulty. So, let’s talk about finding equivalent fractions! Understanding equivalent fractions is important when comparing and ordering fractions, adding and subtracting fractions with unlike denominators, and reducing fractions to their lowest term. Here are some math concepts you can model with fraction sticks and area models:Ī prevalent theme in the Grade 4 Common Core standards is understanding equivalent fractions, or, more precisely, the notion that a fraction remains the same when you multiply the numerator and denominator by a non-zero whole number. An area model is a square that you divide into equal-sized rectangles to represent a fraction.
