Here is an example of some parts of a Fourth Grade Word Problem
Midyear Benchmark (see Figures 11.4, 11.5 and 11.6). Notice that the students
are asked to model their thinking with a drawing, number line or tape
diagram. It is important that students show their knowledge of the desig-
nated models of their math state standards. This test also requires that
students write a set-up equation with a symbol for the missing part. All
state standards require that students learn how to do this starting in first
or second grade. However, most classroom assessments tend to look for a
solution equation rather than require students to write set-up equations.
