# Q4W5 (4/18 – 4/22)

Teacher Kathleen Manning Math/Science 4 5 Angles and Angle Measurement/Inherited vs Environmental Characteristics
Standard(s) Taught

MATH: MAFS.4.MD.3.5 MAFS.4.MD.3.7 MAFS.4.G.1.1

– Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint and understand concepts of angle measurement.
– Recognize angle measurement as additive. When an angle is decomposed into nonoverlapping parts, the angle measure of the whole is the sum of the angle measures of the parts.
– Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two dimensional figures.

SCIENCE: SC.4.L.16.2

– Explain that although characteristics of plants and animals are inherited, some characteristics can be affected by the environment.

Learning Targets and Learning Criteria

The student will:

– Recognize an angle as a geometric shape that is formed when two rays share a common endpoint.
– Explain the relationship between a circle and the number of degrees in an angle (i.e., an angle is measured in reference to
a circle—its center is the endpoint for each of the rays that make up the angle).
– Explain an angle as a series of “one-degree turns” and the total number of “one-degree turns” is the measure of the angle
in degrees (°).
– Explain that since it takes 360 “one-degree turns” to rotate through a circle, 1/360 of a circle is a “one-degree angle”
– Measure an angle to the nearest whole number degrees using a protractor.
– Recognize angle measure as additive, explaining that the angle measurement of a larger angle is the sum of the angle
measures of its decomposed parts.
– Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems.
– Draw points, lines, line segments, rays, right angles (exactly 90°), acute angles (less than 90°), obtuse angles (greater than
90° and less than 180°).
– Identify points, lines, line segments, rays, angles (right, acute, obtuse) in two-dimensional shapes.
– Explain that some characteristics (traits) of plants are inherited by offspring from parents (e.g., type of plant, color of flower, leaf
shape, size).
– Explain that some characteristics (traits) of plants are affected by the environment (e.g., fires, humans, pollution, diet, temperature,
amount of sunlight).
– Explain that some characteristics (traits) of animals are inherited by offspring from parents (e.g., freckles, height, dimples, eye color,
fur color, beak size, beak shape, camouflage).
– Explain that some characteristics (traits) of animals are affected by the environment (e.g., feather color based on diet, fur length based
on temperature, gender of offspring based on temperature).
