    Step 2 - Decide how youre goingto solve the problem

    Choose a method

    Use a graph Use formulas

    Write an equation Make a listFind a pattern Work backwards

    Use reasoning Draw a pictureMake a table Act it out

    Step 2 - Decide how youre goingto solve the problem

    Write your equation

    Since I know both weeks total 31 Iwrite

    14 + s = 31

    Total = 31 1st week =142nd week = ?

    Step 2 - Decide how youre goingto solve the problem

    Write your equation

    I can use the inverse operation to solvefor s

    14 + s = 31 3114 = s

    Total = 31 1st week =142nd week = ?
