AIM: How can we practice adding and subtracting rational numbers?
Classwork: After learning various ways to add and subtract rational numbers -- including number lines, integer chips, and addition and subtraction algorithms -- students are given a practice period to refine their skills. They can work through a problem set by themselves using their notes a resource. They can also ask their desk partner or neighboring students for assistance before asking the teacher for intervention. Answers will be shared at the end of the period to allow for student self-assessment and self-reflection. Students should use their success in today's practice lesson as a guage for how much time to commit to tonight in preparation for tomorrow's quiz on rational numbers.
The column on the right with the play button has helpful videos. The buttons with a star are problem sets you can use to test your abilities.
