Introducing Fractions

Standards CCSS.MATH.CONTENT.4.NF.B.3Understand a fraction a/b with a > 1 as a sum of fractions 1/b. CCSS.MATH.CONTENT.3.NF.A.1Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b. Summary Before you jump into teaching how to add, subtract, multiply or divide

A denominator is the number of parts a whole is divided into

Standards CCSS.MATH.CONTENT.4.NF.B.3.CAdd and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction. Summary Now that you understand what a fraction is, what’s a numerator and what’s a denominator, you can start doing operations with fractions.

Standards Apply and extend previous understandings of multiplication and division. CCSS.MATH.CONTENT.5.NF.B.3Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem.  Visualizing the

Video: When is a Fraction the Same as One?

When first learning fractions, I’ve found most students benefit from lots and lots of examples. It’s fine to teach rules and procedures, which I do, but I also try to show that rule applied in many different contexts. Watch this video for many examples of how N/N = 1 . Whether it is one trip,
