THE NUMBER SYSTEM --UNIT 1

Unit 1.1

I can describe situations in which opposite quantities combine to make zero.

I can show that a number and its opposite have a sum of zero (are additive inverses.)

Unit 1.2

I can represent addition of rational numbers on a vertical or horizontal number line using the sign of the value being added to determine direction.

I can describe sums of rational numbers in real world contexts.

Unit 1.3

I can use the additive inverse to write a subtraction problem as an addition problem.

I can show the distance between two rational numbers on the number line is the absolute value of their difference.

I can subtract rational numbers in real world contexts.

Unit 1.4

I can add rational numbers using the properties of operations.

I can subtract rational numbers using the properties of operations.

Unit 1.5

I can relate the properties of multiplication of fractions to the multiplication of rational numbers.

I can use the rules for multiplying signed numbers to determine the sign of the product.

I can interpret products of rational numbers by describing real world situations.

I can multiply rational numbers using the properties of operations, particularly the distributive property.

Unit 1.6

I can explain why dividing by zero is undefined.

I can use the rules for dividing signed numbers to determine the sign of the quotient.

I can interpret quotients of rational numbers by describing real world situations.

I can divide rational numbers using the properties of operations.

Unit 1.7

I can convert rational numbers into decimals using long division.

Unit 1.8

I can use order of operations to solve mathematical problems with rational numbers, including complex fractions.

I can use order of operations to solve real world problems with rational numbers.
