NAME _______________________________________
Unit 5
1.
Demonstrate an understanding of adding and subtracting positive fractions and mixed
numbers, with like and unlike denominators, concretely, pictorially and symbolically .
A
Model addition of positive fractions, using concrete representations, and record
symbolically
B
Determine the sum of two given positive fractions with like denominators.
C
Determine a common denominator for a given set of positive fractions.
D
Simplify a given positive fraction by identifying the common factor between the
numerator and denominator.
E
Model addition of positive fractions with unlike denominators, using concrete
representations, and record symbolically.
F
Determine the sum of two given positive fractions with unlike denominators.
G
Model subtraction of positive fractions, using concrete representations, and record
symbolically
H
Determine the difference of two given positive fractions with like denominators.
I
Determine the difference of two given positive fractions with unlike denominators.
J
Model addition and subtraction of mixed numbers with like denominators, using
concrete representations, and record symbolically
K
Determine the sum or difference of two mixed numbers with like denominators
L
Model addition and subtraction of mixed numbers with unlike denominators, using
concrete representations, and record symbolically
M
Determine the sum and difference of two mixed numbers with unlike denominators.
N
Simplify the solution to a given problem involving the sum or difference of two positive
fractions or mixed numbers
O
Solve a given problem involving the addition or subtraction of positive fractions or
mixed numbers, and determine if the solution is reasonable.
