drawing a diagram for an algebraic expression

[ceseve99]

hello!

i'm tutoring a 4th grader and cant seem to grasp the concept they are working on in school.

the problems states to draw a diagram using two actions to show the expression.

example: (m x 4) + 7
action 1: m m m m
action 2: m m m m 7

i understand the example shows m 4 times because that is the first part of equation and then they just add the 7

but the other problems are harder to understand. can someone please help me?

1. (t/2) - 4
2. (p-9) + 6
3. (w+3)/5

thanks!

Good luck with that. I wonder what concept is intended?

Anyway, have fun with that when you get to irrational numbers.
