Subtracting Fractions with Mixed Numbers and the Same Denominator WORKSHEET

Suitable for Grades: 4th Grade
CCSS: 4.NF.B.3.C
CCSS Description: Understand a fraction a/b with a > 1 as a sum of fractions 1/b. c. Add 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.

Subtracting Fractions with Mixed Numbers and the Same Denominator WORKSHEET DESCRIPTION

This worksheet is designed to scaffold a method for subtracting fractions and mixed numbers without the need for converting between improper fractions and mixed numbers. It uses a number line to help learners count back to the position required. There is also a worksheet for addition using the same method. Section A begins with some questions where learners can use a number line to subtract a fraction from a whole number. Section B then provides scaffolding to help learners subtract a mixed number from an integer by first subtracting the integer part of the mixed number. Section C then again provides number lines to help learners subtract a fraction from a mixed number where the answer will have a lower integer value. Section D then leads learners through a process of subtracting one mixed number from another but subtracting the integer part first.
