CCSS.5.NF.A.2 Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 [less than] 1/2.

TEKS.7.3.B apply and extend previous understandings of operations to solve problems using addition, subtraction, multiplication, and division of rational numbers.

TEKS.5.3.A estimate to determine solutions to mathematical and real-world problems involving addition, subtraction, multiplication, or division;

TEKS.5.3.H represent and solve addition and subtraction of fractions with unequal denominators referring to the same whole using objects and pictorial models and properties of operations;

TEKS.5.3.K add and subtract positive rational numbers fluently; and

IN.5.AT.2 Solve real-world problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators (e.g., by using visual fraction models and equations to represent the problem). Use benchmark fractions and number sense of fractions to estimate mentally and assess whether the answer is reasonable.

VA.CE.6.5.b solve single-step and multistep practical problems involving addition, subtraction, multiplication, and division of fractions and mixed numbers; and

VA.CE.5.6.a solve single-step and multistep practical problems involving addition and subtraction with fractions and mixed numbers; and

VA.PFA.5.19.d create a problem situation based on a given equation, using a single variable and one operation.

FL.MAFS.5.NF.1.2 Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 [less than] 1/2.
