Wisdom from the math professor

- Again everyone solves a problem differently depending on how they see it.
When you see the problem 15 + 19, does your mind solve by:

15
+19

or 15+20-1

or 15+19=14+10


- "Get into the habit of writing addition and subtraction problems horizontally (46 + 37) this allows the students to give meaning to the numbers as 10s and 1s"

- "Help students figure out how to turn a math problem into a friendly problem. One that they can solve easily"
ex: 46+37
40 + 30
6 + 7
70 + 13
OR: using doubles
ex: 25+28
25 + 25 + 3

- When a student shows you a way to solve a problem that you are unfamiliar with, or if their process isn't what you want, say, "Oh, I thought about it so differently. Show me your thinking"

- If a student is unsure about sharing their process in front of others say, "We're in a place where we all share our thinking"
