math 4 Updates
When we return from break your 4th grader will focus on multiplying fractions. In some cases, results will be improper fractions. We are learning how to convert improper fractions, when the numerator is larger than the denominator, into mixed numbers. For example, 7/4 is equal to 1 whole and ¾. We find this by relating fractions to division. 7 divided 4 would be 1 remainder 3. The remainder becomes the numerator and the divisor becomes the denominator. This video helps explain the concept. https://www.khanacademy.org/math/arithmetic/fractions/mixed_numbers/v/changing-an-improper-fraction-to-a-mixed-number

4th grade continues to study adding and subtracting fractions. These operations will be applied to fractions with common denominators, unlike denominators, and we will also begin to use mixed numbers larger than 1 whole. We use many visual representations to model fractions in order to make this abstract concept more tangible. Models include fraction kits, circles with slices like a pizza, rectangular area models, number lines, pictures to go along with word problems, and counters such as beans.
4th grade will deepen their understanding of fractions next week. So far we have identified fractional parts of a given whole and part of a set, and we have compared fractions with different denominators. Next week we will get into adding and subtracting fractions First we will use fractions with common denominators, and then we will learn several strategies for adding fractions with unlike denominators. Knowledge of multiplication facts will help us in this process of creating common denominators. This video will aid our understanding. https://learnzillion.com/resources/72985-understand-addition-and-subtraction-of-fractions-and-decomposing-fractions-4-nf-b-3a We are looking forward to seeing you at Nea Night Out tomorrow, Saturday the 5th! This week we continue to talk about equivalent fractions. Students are exploring fractions on the number line and using number strips to identify equivalent fractions. We will compare fractions with different numerators and denominators by using this method. We are drawing pictorial models to show we understand the concept of equivalent fractions.
Some Questions you can ask your learner... Can you identify two equivalent fractions? How do you know those fractions are equivalent? Choose two fractions to compare. Which fraction is larger? Video to Introduce the concept: How Do we Compare Fractions? |
