Accentuate the Negative 2.1 and 2.2 - Clarifying algorithms for subtraction and addition.
Algorithm for adding:
If addends have the same sign then COMBINE.
Example:
2 + 8 = 10
-2 + -8 = -10
8 +12 = 20
- 8+ -12 = -20
If addends have opposite signs CANCEL and the sum takes the sign of the addend with the larger absolute value (number further from zero).
Example:
2 + -8 = -6
-2 + 8 = 6
8 + -12 = -4
-8 + 12 = 4
Algorithm for subtracting:
Subtracting is the same as adding the opposite of the second number (subtrahend).
Example:
-4 - 3 = -7
-4 + - 3 = -7
8 - 3 = 5
8 + -3 = 5
6 - -7 = 13
6 + 7 = 13
If addends have the same sign then COMBINE.
Example:
2 + 8 = 10
-2 + -8 = -10
8 +12 = 20
- 8+ -12 = -20

6 + 7 = 13

November 8th - Accentuate the Negative - Unit #2
Our students have started the next Unit- Accentuate the Negative.
Investigation 1.1 -
This Investigation gives students experiences with rational numbers, ordering numbers, and informal operation computations in a variety of contexts.
Investigation 1.2 -
This Investigation uses temperature measurement to extend number lines to include negative numbers. Students estimate values of positive and negative points on a number line. They develop informal strategies for comparing, ordering, and locating numbers and their opposites on a number line.
There is a high focus on inequalities We went over notes explaining how to graph these on a number line.
Here are some examples. The circle is filled if equal to and not if it is just greater than or less than.
x > 2
