Unit 3: Fraction Equivalents

This unit is all about fractions!  Your child briefly discussed fractions in 3rd grade, but this will be their first time really digging into what fractions are and what they represent!  Any conversation you can have with your child about fractions will be a huge help.  This is a brand new concept for their little brains to try to understand!  Visual representations are extremely useful with fractions.  You will see and hear the words tape diagram a lot.  A tape diagram is simply a rectangle split into sections to represent a fraction.  We will specifically be discussing why and how some fractions are equivalent, and comparing fractions.  When comparing fractions we use many methods including : visual models, creating a common denominator, and using benchmark fractions.

Unit 3 Standards

MGSE4.NF.1: Explain why two or more fractions are equivalent a/b = n x a/n x b ex: 1/4 = 3 x 1/3 x 4by using visual fraction models. Focus attention on how the number and size of the parts differ even though the fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

MGSE4.NF.2: Compare two fractions with different numerators and different denominators, e.g., by using visual fraction models, by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2.  Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions. Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers.
