Directed (Negative) Numbers
Two options for teaching directed numbers:
Using double-sided counters is a new lesson that shows clearly the four operations with directed numbers. Includes questions from VariationTheory.com. Use MathsBot manipulatives to support teaching and student tasks.
The number line lesson on directed numbers starts at the beginning with where we encounter them in real life. The PowerPoint features a video by Fuse School (found here if you have problems playing in the PowerPoint) with questions to keep students focused. Tasks on adding and subtracting, then multiplying and dividing, are differentiated and answers are included.
