Finding the Whole (A) WORKSHEET

Suitable for Grades: 5th Grade
CCSS: 5.NF.B.3, 5.NF.B.6
CCSS Description: Interpret 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. For example, interpret 3/4 as the result of dividing 3 by 4, noting that 3/4 multiplied by 4 equals 3, and that when 3 wholes are shared equally among 4 people each person has a share of size 3/4. If 9 people want to share a 50-pound sack of rice equally by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie?

CCSS Description: Solve real world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem.

Finding the Whole (A) WORKSHEET DESCRIPTION

Finding the Whole (A) is designed to enhance students' understanding of fractions and will see them finding the whole when given a part.

The worksheet begins by using concrete examples of chocolates in a box and sweets in a bag in order to introduce the concept of finding the whole when a fractional part is unknown.

Next, learners are given unit fractions of amounts such as ¼ = 9 and bar models to use in order to find the whole. The scaffolding provided for pupils decreases throughout the section.

In section C, pupils are given a chance to articulate their understanding as they decide whether they agree or disagree with two statements about the method used.

By section D, your students are ready to find the whole when given a unit fraction or an amount without the support of a bar model as here they will answer a further six questions.
