5.NF.A1
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)

Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 … Read More “5.NF.A2”
October 1, 20185.NF.B3
Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem. For example, interpret 3/4 as the result of … Read More “5.NF.B3”
October 1, 20185.NF.B4
Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.
October 1, 20185.NF.B4b
Find the area of a rectangle with fractional side lengths by tiling it with unit squares of the appropriate unit fraction side lengths, and show that the area is the same as would be found by multiplying the side lengths. Multiply fractional side lengths to find areas of rectangles, and represent fraction products as rectangular … Read More “5.NF.B4b”

Comparing the size of a product to the size of one factor on the basis of the size of the other factor, without performing the indicated multiplication.
October 1, 20185.NF.B6
Solve real world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem.
October 1, 20185.NF.B7
Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.1
October 1, 20185.NF.B7c
Solve real world problems involving division of unit fractions by non-zero whole numbers and division of whole numbers by unit fractions, e.g., by using visual fraction models and equations to represent the problem. For example, how much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 1/3-cup servings … Read More “5.NF.B7c”

Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.
October 1, 20185.G.A1
Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates … Read More “5.G.A1”
