How to teach it
- Equivalent fractions: multiply or divide the numerator and the denominator by the same number.
- Comparing: with the same denominator, compare numerators; otherwise rewrite both over a common denominator.
- Adding and subtracting: the denominators must match first. Add or subtract the numerators and keep the denominator.
- Mixed numbers: add the wholes and the fractions, then regroup if the fraction part is one or more.
Questions teachers ask
- When do students learn fractions?
- In the Common Core, fractions as numbers and on a number line start in Grade 3 (3.NF), adding and subtracting like denominators is Grade 4 (4.NF.B.3), and unlike denominators is Grade 5 (5.NF.A.1).
- Do the answers have to be in lowest terms?
- Each question says when it does. The answer key gives answers in lowest terms, and mixed numbers where the question asks for them.
