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

x > -2

x < 3
