"I am looking forward to learning new kinds of math (not CSMP)"
"Dylan can help me learn by assigning a fair amount of homework and doing a lot of problems in class."
"I expect my math teacher to a calm teacher that answers questions sensibly."
"Switching from CSMP to Pre-Algebra is my biggest concern"
"I like taking notes and applying them to problems"
"Dylan can help me by working with me individually when I need help"
"I like to learn by discussing it in class and doing problems in class."
"Make math fun so that I can feel relaxed about it."
"I have not enjoyed math but I do enjoy doing math on my own to figure something out"
"I am concerned that I will be unprepared and stressed about tests"
"I like working in small groups or problems in class"
"I am concerned about not gettign the homework done"

1.1 Date:
• I CAN write and evaluate variable expressions.
You can use your note sheet from yesterday or start a new one
September 5, 2019
Solve each and then check your answer with your partner.
Evaluate each when u = 5 and v = 15.
Re-visiting from Yesterday:
September 5, 2019
With your partner, get a large whiteboard for your table, an eraser, and markers for each of you.
Each problem will have a scenario. Your job is to define your variable(s), write a variable expression, and then evaluate it for the random number that comes up on our random number generator.
Let's practice writing variable expressions:
