Q1, W3: September 14th – 18th Advanced Math

MAFS.7.NS.1.1

Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.

1. Describe situations in which opposite quantities combine to make 0.

2. Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses).   Interpret sums of rational numbers by describing real-world contexts.

3.  Understand subtraction of rational numbers as adding the additive inverse, p – q = p + (-q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.

4. Apply properties of operations as strategies to add and subtract rational numbers.

MAFS.7.NS.1.3

Solve real-world and mathematical problems involving the four operations with rational numbers.

Students are successful when they can…

• multiply positive and negative integers using properties of operations.
• represent multiple “zeros” by combining the same number of positive and negative counters.
• model positive and negative combining to make zero in real-world situations
• model on a number line how a certain number of moves in a positive direction from zero combined with the same number of moves in opposite direction ends at a zero on the number line.
• define additive inverse as a rational number added to its negative which results in a sum of zero.
• define the direction of the distance on a number line based on the sign of the addend.  Negative is left/down and positive is right/up.
• define the sum of two rational numbers as the distance one addend is away from the total by the absolute value of the other addend.
• calculate the distance between two rational numbers by finding the absolute value of their difference.
• compare subtracting rational numbers to adding the additive inverse.
• solve real-world problems that involve the addition, subtraction, multiplication, and/or division of rational numbers.
