This is the most basic root standards of the entire linear systems unit. Here the students will
learn how to identify objects as they notice the likenesses and differences of the objects they
are working with. Now typically in these grade levels, they will be working a lot more hands
on so their objects will be pertaining more towards concrete objects, but this gets the ball
rolling towards understanding linear systems later on. Students at this age are also required
to demonstrate numeral relationships as well as the mathematical processes that can be
asked when given a data set. However the interesting part of how both standards documents
grouped this age group together. Now there will be progression throughout the standards and
the lessons where the students will gradually be given more advanced work as they continue
to master their previous material. Nonetheless it is rather interesting that these grades were
grouped the way they were.

Much to the same degree of the standards for the kindergarten through second grade
standards, the standards between third grade through fifth grade are grouped together
though only truly in the national standards. The state standards do dive a bit more in depth
with each grade regarding each of the standards that the students must master in their grades
however they do not differ too much. Granted this is partly due to the fact that the students
are still progressing through the material, and it’s difficult to give one an advanced concept
and to expect them to understand it without building up the foundations of that material first.
In these grades, the students work more with understanding their numerical operations as
well as mastering the relationships between different types of numbers. This will do wonders
for the foundations of linear systems as this will help the students understand how to solve
the systems of linear equations such as substitution or elimination. They will also work with
functions and equations in these grades. Although they might not necessarily refer to the
problems that they work as equations, they will be able to build off what they are learning to
help establish the concept of equations and functions in the later grades.

Again much like the previous sections of the standards where they were grouped according to
certain grades such as the grades of kindergarten through second as well as the grades of third
through fifth, the national standards groups the sixth grade through the eighth grade the
same. However the big difference from the previous two groupings is that the national
standards actually stay the same going into high school. However that might be misleading
some so allow me to clarify. Although the standards stay the same, the expectations that
come with each standard differ in that as the standards progress through the grades, the
expectations seek a deeper understanding of the standards. This is beneficial for teachers in
that these standards are aided with the state standards that do state a more clearer point of
view of what is expected. Now in these grades the students will be building on their
knowledge about functions. Here they will be expected to learn about relationships between

equations and inequalities as well as linear functions. Once they have learned about linear
functions and how to solve for the variable(s) in the linear functions, then they will be halfway
there to understanding systems of linear equations.

Finally we have reached the high school standards. These standards are not possible without
the building of the previous standards all the way from kindergarten. Here the students will
add the final layers of their knowledge to the foundation that they’ve made. Once they have
mastered all that previous knowledge regarding numerical operations, functions, linear
equations, etc., then they will be able to put the pieces together to comprehend linear
systems. If the students are missing some of the previous standards and expectations, then it
will take a bit longer for the concept of linear systems to set in as the teacher would have to
reteach what the student does not understand. However this is the culmination of those many
standards from kindergarten.
