How confident do you feel about evaluating algebraic expressions?

• I'm very confident and ready to go on to the assignment.

• I think I understand and want to try the assignment, but if I struggle, I'll ask for help.

• I don't feel confident so I'm going to stay in the Google Meet and get help.

Today's assignment is a 15 question Quizziz assignment and the link can be found on slide 6
