fraction – a number that names part of a while or part of a group
equivalent fractions - two or more fractions that name the same amount
decimal – a number with one or more digits to the right of the decimal point
decimal point – a symbol used to separate dollars from cents in a money amount; to separate the ones and the tenths place in a decimal
equivalent decimals – two or more decimals that name the same amount
compare - to describe whether numbers are equal to, less than, or grater than each other
tenth - one of ten equal parts
hundredth - one of one-hundred equal parts
Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers
CC.4.NF.3 Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8; 3/8 = 1/8 + 2/8; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.
Add and subtract mixed numbers with like denominators, e.g., be replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction.
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.
