Standards for Mathematical Practice
1. Make sense of problems and persevere in solving them. Students make
sense of problems and persevere in solving them by exploring and
investigating properties of geometric figures and lines of symmetry.
Students solve problems involving measurement and the conversion of
measurements from a larger unit to a smaller unit.
2. Reason abstractly and quantitatively. Students reason abstractly and
quantitatively by comparing, contrasting, and classifying two-dimensional
shapes and determining their lines of symmetry. Students recognize angle
measure as additive in relation to the reference to a circle.
3. Construct viable arguments and critique the reasoning of others. Students
construct viable arguments and critique reasoning when determining the
properties of geometric shapes and determining their lines of symmetry.
Students construct and critique arguments regarding the relative size of
measurement units and relating them to everyday objects.

4. Model with mathematics. Students model with mathematics by drawing,
folding, tracing, and constructing lines of symmetry and categorizing twodimensional shapes based on their properties. Students use line plots to
display data of measurements in fractions of a unit.
5. Use appropriate tools strategically. Students use appropriate tools such as
geometric shapes, corners of paper, tiles, rulers, protractors, and/or
graphic organizers to determine angles, classify two-dimensional shapes,
and draw lines of symmetry. Students select and use tools such as a ruler,
balance, graduated cylinder, angle ruler, and protractor to measure.
6. Attend to precision. Students attend to precision when observing and
determining the attributes of sides and degree of angles within geometric
shapes. Students carefully specify unit measure and state the meaning of
the symbols they choose.
7. Look for and make use of structure. Students look for and make sense of
structure when exploring properties of geometric shapes and determining
how to fold them to show lines of symmetry. Students use the structure of a
two-column table to generate a conversion table for measurement
equivalence.
8. Look for and express regularity in repeated reasoning. Students look for
and express regularity in repeated reasoning while exploring the geometric
properties of two-dimensional shapes by comparing, contrasting,
classifying, and identifying lines of symmetry. Students notice repetitive
actions in computations to make generalizations about conversion of
measurements from a larger unit to a smaller unit.
Standards for Mathematical Content
 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 based on the presence or absence
of parallel or perpendicular lines, or the presence or absence of angles of
a specified size. Recognize right triangles as a category, and identify right
triangles.
 4.G.3 Recognize a line of symmetry for a two-dimensional figure as a line
across the figure such that the figure can be folded along the line into
matching parts. Identify line-symmetric figures and draw lines of symmetry.
 4.MD.3 Apply the area and perimeter 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 equation with an unknown
factor.
 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 “one-degree angle,” and can be used to measure angles.
b. An angle that turns through n one-degree angles is said to have
an angle measure of n degrees.
 4.MD.6 Measure angles in whole-number degrees using a protractor.
Sketch angles of specified measure.
 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.OA.3 Solve multistep word problems posed with whole numbers and
having whole-number answers using the four operations, including
problems in which remainders must be interpreted. Represent these
problems using equations with a letter standing for the unknown quantity.
Assess the reasonableness of answers using mental computation and
estimation strategies including rounding.
 4.MD.2 Use the four operations to solve word problems involving
distances, intervals of time, liquid volumes, masses of objects, and money,
including problems involving simple fractions or decimals, and problems
that require expressing measurements given in a larger unit in terms of a
smaller unit. Represent measurement quantities using diagrams such as
number line diagrams that feature a measurement scale.
