4.MD.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 “onedegree angle,” and can be used to
measure angles.
4.MD.5 Recognize angles as geometric
shapes that are formed wherever two rays
share a common endpoint, and understand
concepts of angle measurement:
B. An angle that turns through n
one-degree angles is
said
to have an angle measure of n
degrees.
I can define angle.
I can recognize a circle as a
geometric figure that has 360
degrees.
I can recognize and identify an angle
as a geometric shape formed from 2
rays with a common endpoint.

I can sketch angles of specified
measure.
I can determine which scale on the
protractor to use, based on the
direction the angle is open.
4.MD.7 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.
4.G.1 Draw points, lines, line segments,
rays, angles (right, acute, obtuse), and
perpendicular and parallel lines. Identify
these in two-dimensional figures.
4.G.2 Classify two-dimensional figures

parallel or perpendicular lines, or the
I can determine the kind of angle
based on the specified measure to
decide reasonableness of the sketch.
I can solve addition and subtraction
equations to find unknown angle
measurements on a diagram.
I can find an angle measure by
adding the measurements of the
smaller angles that make up the
larger angle.
I can find the angle measure by
subtracting the measurements of the
smaller angle from the larger angle.
I can analyze two-dimensional
figures to identify points, lines, line
segments, rays, angles (right, acute,
obtuse), and perpendicular and
parallel lines.
I can classify two-dimensional figures
based on parallel or perpendicular
lines and size or angles.

the reasonableness of answers using mental
computation and estimation strategies

formulas for rectangles in real world and
mathematical problems. For example, find
the width of a rectangular room given the
area of the flooring and the length, by
viewing the area formula as a multiplication
