In this Investigation, the students experienced adding and subtracting positive and negative rational numbers, by modeling real-world situations using different models. The most non-intuitive computation was subtracting negative numbers. For examples : why 4 – (-2) = 6 ?
Ask your child to use the chip board model ( red & black chips ) explaining why it does make sense.
We also strength our skills using our class favorite activity – Kahoot.
Did the kids ending up making that Kahoot? I know they were really excited about it, but what a wonderful opportunity for student ownership of their learning if they did!
