Notebook:
A rational number is a number that can be written as a ratio. A rational number is usually written like this:
A rational number is a number that can be written as a ratio. A rational number is usually written like this:
As long as b doesn't equal zero. (Dividing by zero would give us infinity, which is not a rational number)
Classwork & Homework:
State Test Practice:
California Standards:
CCSS.Math.Practice.MP4 Model with mathematics.
CCSS.Math.Practice.MP7 Look for and make use of structure.
CCSS.Math.Content.6.NS.C.6 Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates.
CCSS.Math.Content.6.NS.C.7 Understand ordering and absolute value of rational numbers.
CCSS.Math.Content.6.NS.C.7.b Write, interpret, and explain statements of order for rational numbers in real-world contexts. For example, write -3 oC > -7 oC to express the fact that -3 oC is warmer than -7 oC.
CCSS.Math.Content.6.NS.C.7.d Distinguish comparisons of absolute value from statements about order. For example, recognize that an account balance less than -30 dollars represents a debt greater than 30 dollars.
