Class Experience

In this course, students will:
*Understand that positive and negative numbers are used to describe quantities having opposite directions or values.
*Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line. 
*Show that a number and its opposite are additive inverses.
*Model addition of positive and negative rational numbers using hands-on or virtual maniuplatives.
*Demonstrate the addition of positive and negative rational numbers.
*Explain that the opposite of the opposite of a number is the number itself.
Teacher feedback on assignments, quizzes and collaborative activities may include suggested assignments for additional practice for individual learners who demonstrate gaps in the learning goals.
Students are expected to have access to the manipulatives listed below. Students can print their own manipulatives from the teacher provided handouts or may purchase the physical items from online vendors. Several of the manipulatives are available virtually, as indicated below.

*Double Sided Counters (Also available as virtual manipulatives)
*Base Ten Blocks (Also available as virtual manipulatives)
