Weaving 8th Grade
Standards into MS Math 1

Purpose
★ Our students are held accountable for both their
grade-level math standards AND the Math 1
standards, even though they are only receiving
instruction for Math 1.
★ Their success in both courses is important.
★ How do we, in the short amount of time we
have, give students access to both sets of
standards?
8.NS.1
Give students the task of devising a
plan that would always work for
converting repeating decimals into
their equivalent fractions. Great
investigation, and post-discussion
would hit practice standard #3!
8th Grade: 8.NS.1 Math 1: A-CED.1
Review with solving
quadratics. Have
students place solutions
to ax2 + c = 0 type
equations on the number
line.
8th Grade: 8.NS.2 Math 1: A-CED.1
Have students express really large
(exponential growth) values or really
small (exponential decay) values in
scientific notation in tables or on
graph axes.
8.EE.4 also involves operating with numbers in scientific notation (+, -, *, /)
8th Grade: 8.EE.3 & 8.EE.4 Math 1: F-LE.1, F-LE.2, F-LE.3
Review with domain, range,
and definition of function.
Students can also calculate
average rate of change from
these sorts of graphs.
8th Grade: 8.F.5 Math 1: F.IF.4, F.IF.5, F.IF.6
A lesson on this standard could be
a time to tie in distance and
midpoint to verify the congruence
of a preimage and an image!
Students can also prove
parallel/perpendicular segments
both before and after
transformations.
8th Grade: 8.G.1 Math 1: G.GPE.4, G.GPE.5, G.GPE.7, G.
CO.1
Distance,
midpoint,
slope,
transformation of
functions.
8th Grade: 8.G.2, 8.G.3, & 8.G.4 Math 1: G.GPE.4, G.GPE.5,
G.GPE.7, G.CO.1, F.BF.3
Rearrange
formulas to
highlight a quantity
of interest
Use volume
formulas for
cylinders,
pyramids, cones,
and spheres to
solve problems. At
this level, formulas
for pyramids,
cones and spheres
will be given.
8th Grade: 8.G.9 Math 1: A.CED.4, G.GMD.3
Teach with
relative
frequency
histograms
for two
applications
of relative
frequency.
8th Grade: 8.SP.4 Math 1: S.ID.5
Other Geometry Standards
(8.G.5-8)
8.G.5:
● angle sums and exterior angle sums of
triangles,
● angles created when parallel lines are cut by
a transversal,
● the angle-angle criterion for similarity of
triangles.
● the measure of an exterior angle of a triangle
is equal to the sum of the measures of the
other two interior angles and the sum of the
exterior angles 360º.
● find the measure of missing angles.
8.G.6-8:
● Pythagorean Theorem
This one’s tough,
perhaps it demands its
own mini-unit. Maybe
during the end-of-year
review?
Weave in with
geometry standards
(use coordinates to
compute perimeters)
where students need
distance/midpoint.
Implementation Ideas
● Small Groups
○ stations
○ weekly workplan model
● Build in the 8th grade standards to end-of-year review time
rather than regular instruction
● Use videos (Khan Academy, LearnZillion) for quick and
easy 8th grade lessons to be added into your existing units
for Math 1
● modify existing assignments and activities to simply include
2-3 additional tasks that assess 8th grade
○ cut and past 2-3 released 8th grade EOG questions
Example: Weekly Workplan

Questions?
●
Take time to think of an existing
activity, something you already
use, and brainstorm how it could
be tweaked to cover both 8th and
9th grade content.
