In Chapter 7 students will:
Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers
Vocabulary:
fraction – a number that names part of awhile or part of a group
numerator - the part of a fraction above the line which tells how many parts are/not being counted
denominator – the part of the fraction below the line which tells how many equal parts there are in a whole or a group
mixed number – an amount given as a whole number and a fraction (3 1/2)
unit fraction – a fraction that has a numerator of one
simplest form - a fraction in which the numerator and denominator have only 1 as a common factor
Associative Property of Addition - the property that states that when the grouping of addends is changes, the sum is the same
(ex. 7 + 3 + 2 = (7+3) + 2 or (3+2) + 7)
Commutative Property of Addition - the property that states that when the order or two or more addends is changes, the sum is the same
(ex. 3 + 4 = 4 + 3)
