oval = 230
hexagaon = 115
triangle = 88
square = 440
circle = 40
diamond = 78
This is becuase, at this level, the comma after each equation is assumed
(i.e., diamond - 38 = circle, circle x 11 = square, etc.). As written, of
course, we see parenthesis around the statements between the equal signs,
which produces 6 equations, each of which equals 211, giving much different
answers, including fractional results that are probably beyond what most
third graders are used to seeing.
I agree the teacher should be more accurate, but I wouldn't get too upset
about it. Third graders, in general, are not yet mathematics professionals.

Subject: Third Grade Math
The following problem was presented to a group of third graders. I have a
solution from the teacher that I disagree with. I thought I would pose the
problem to a group of mathematics professionals and see if anyone comes up
with the teachers answer.
I will state the problem twice as I am not sure how these things will
translate in the various e-mail systems.
In words:
Diamond minus 38 equals Circle times 11 equals Square divided by 5 equals
Triangle plus 27 equals Hexagon times 2 equals Oval minus 19 equals Star.
Star equals 211. What number should replace each shape.
In symbols:
diamond - 38 = circle x 11 = square /5 = triangle +27 = hexagon x 2 = oval
- 19 = star
Star = 211. What number should replace each shape.
