    drawing a diagram for an algebraic expression

    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.
