Representing & Solving Adding & Subtracting Fractions

T.i.P.S.

Students will select tools (manipulatives including pattern blocks or pictorial models) to create and use representations to solve addition and subtraction problems. These problems will include fractions with equal denominators. The models lay a foundation for using the number line and properties of operations.

Example

Paula wants to make a blanket for her new baby. The pattern calls for 2 1/3 yards of fabric and she only has 2/3 yards. How much fabric should she buy so she can make the blanket? Using pattern blocks and a number line model to justify your thinking.

Hint
Possible Solution

TEKS

Readiness Standard 4.3 Number and operations. The student applies mathematical process standards to represent and generate fractions to solve problems.
(E) represent and solve addition and subtraction of fractions with equal denominators using objects and pictorial models that build to the number line and properties of operations
