1. Grade 7 Writing Rational Numbers as Decimals
Ratios and Proportional Relationships
Apply and Extend previous understanding of multiplication and division and of fractions to multiply and divide rational numbers
Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units
Adding and Subtracting Rational Numbers
Multiplying and Dividing Rational Number
Apply and Extend previous understandings of operations with fractions multiply and divide rational numbers
For Example: if a person walks ½ mile in each ¼ hour, compute the unit rate as the complex fraction ½ over ¼ miles her hour, equivalently 2 miles per four.
Apply and Extend previous understanding of addition of operations with fractions to add and subtract rational numbers
Use proportional relationships to solve multistep ratio and percent problems.
Categorizing decimals as repeating or terminating
Converting rational numbers to repeating decimals
Understand subtraction of rational numbers as adding the additive inverse p-q = p + (-q)
Number of Months

$100 1
$200 2
$300 3
$400 4
$500
For Example: simple interest, tax, mark-ups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.
Describe situations in which opposite quantities combine to make 0.
Understand p + q as the number located a distance from p on the positive or negative directions
Example: 0.23 is terminating but can be written as
Apply properties of operations as strategies to add and subtract rational numbers
7/1000 or 0.075
