Decimals, Fractions and Percents
4.0 Students understand that fractions and decimals may refer toparts of a set and parts of a whole:
4.13 Recognize, name, and compare unit fractions from 1/12 to ½.
4.2 Recognize fractions of a whole and parts of a group (e.g., one-fourth of a pie, two-
thirds of 15 balls).
Know that when all fractional parts are included, such as four-fourths, the result is
equal to the whole and to one.

Decimals, Fractions and Percents
3.0 Students understand the relationship between
whole numbers, simple fractions,
and decimals:
3.11 Compare fractions represented by drawings or concrete materials to show equivalency
and to add and subtract simple fractions in context (e.g., ½ of a pizza is the same amount as 2/4 of another pizza that is the same size; show that 3/8 is larger than ¼).
3.2 Add and subtract simple fractions (e.g., determine that 1/8 + 3/8 is the same as ½

Fractions
2.0 Students calculate and solve problems involving addition, subtraction, multiplication, and division:
2.11/2 Solve problems involving addition, subtraction, multiplication, and division of positive fractions and explain why a particular operation was used for a given situation.
2.21/2 Explain the meaning of multiplication and division of positive fractions and perform the calculations
(e.g., 5/ /16 = 5/ /15 = 2/3).
Integers
Key Standard
2.3 6 Solve addition, subtraction, multiplication, and division problems, including those arising in concrete situations, that use positive and negative integers and combinations
of these operations.

GCF, LCM and Reducing
2.43 Determine the least common multiple and the greatest common divisor of whole numbers; use them to solve problems with fractions (e.g., to find a common denominator to add two fractions or to find the reduced form for a fraction).
