Find each sum.
1) (-12) +7=?
They give us these problems in hopes that we will challenge our zombie brains,
sometimes it does; sometimes it doesn't.
The kids who are amazing at math can answer this quickly and correctly; -5.
The kids who are kinda challenged at math will have a few tries before they get it right; -19? 7? 13? -5!!
The kids have a fit because and blame the teacher because "Well, Mr/Ms/Miss/Mrs didn't explain it good enough! I have no idea what I'm doing!"
Yet they refuse help from another peer or another teacher.
Both teachers and student need to work on their communication and how to help each other.
Think about it like temperature.
Anything below 0 is a nagative (-) number.
Anything above 0 is a positive (+) number.
It's the same way with the number line, anything below zero has no real value so it becomes a negative number, anything above zero have a value so its a positive number.
You have to talk it slow with them;
ignore the negatuve sign for now.
what was the number with the highest sign? The -12
