Partial 6.MG.2.1, 7.MG.1.1
Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min.,
sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit.

Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number
pairs (1, 12), (2, 24), (3, 36),…

Sample Problem: Sally wants to build a pen
for her dog Callie. Her parents give her
$200 to buy the fencing, but want Sally to
design the pen. Her parents suggest that
she consider different plans. Her parents
also remind her that Callie needs as much
room as possible to run and play and that
the pen can be placed anywhere in the yard
and the wall of the house could be used as
one side of the pen. Sally decides to buy
fencing material that costs $8.50 per foot.
She will also need at least one three foot
wide gate for the pen that costs $15.
--Design a pen for Callie. Experiment with
different pen designs and consider the
advice from Sally’s parents. Sally’s house
can also be any configuration. Show your
various design configurations and explain
why certain designs are better for Callie.

4.MG.3.5
Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and
understand concepts of angle measurement.
a. An angle is measured with reference to a circle with its center at the common endpoint of the rays, by
considering the fraction of the circular arc between the points where the two rays intersect the circle. An
angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles.
Essential Skills/Concepts
Prerequisites: definition/examples
of endpoints, circles, rays
Understand that angles are
geometric shapes formed by two
rays that share a common endpoint.
Understand that an angle measure
is a portion of a circular arc that is
formed by the angle when a circle is
centered at their shared vertex
and that the ARC is what is
measured, not the size of the “pie
piece” that the angle makes
(because different size circles
making different size “pie pieces”
but the ARC measurement (i.e. 60o)
is the same, no matter the size of
the circle.)
Understand that there are 360
degrees in a circle and that an angle
that turns through 1/360 of a
circle is called a one-degree angle.
Understand that these degrees can
be used to measure angles.
Teaching Notes/Strategies
Math journals (or a Geometry Book) to record
definitions and draw examples of geometric
shapes.
Use a diagram showing an angle as part of a
circle to help students see than an angle is
determined by the arc it creates relative to
the size of the entire circle.

Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of
the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown
angles on a diagram in real-world and mathematical problems, e.g., by using an equation with a symbol for the
unknown angle measure.
