4.NF.A.2 Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fractions such as 1/2 . Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
4.NF.B.3a Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
4.NF.B.3d Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e.g., by using visual fraction models and equations to represent the problem.
4.MD.A.2 Use the four operations (addition and subtraction) to solve word problems involving distance, intervals of time (rainfall or precipitation over a specific amount of time…hours of growing in a season – temperature), liquid volumes, masses of objects, and money, including problems involving simple fractions.
