Standard(s) Taught
Standard(s) Taught

MATH

4.MD.3.5

• Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement.
1. 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.
2. An angle that turns through n one-degree angles is said to have an angle measure of n degrees.
• 4.MD.3.6,  Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.
• 4.G.1.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse),

SCIENCE

SC.4.P.10.1

• Observe and describe some basic forms of energy, including light, heat, sound, electrical, and the energy of motion.

SC.4.P.10.3

• Investigate and explain that sound is produced by vibrating objects and that pitch depends on how fast or slow the object vibrates.

SOCIAL STUDIES

• SS.4.A.3.8

Explain how the Seminole tribe formed and the purpose for their migration

• SS.4.A.2.10

Identify the causes and effects of the Seminole Wars

Learning Targets and Learning Criteria

MATH

1. Explain the relationship between a circle and the number of degrees in an angle (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).
2. 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.

E.g., A water sprinkler rotates one-degree at each interval. If the sprinkler rotates a total of 100 one-degree turns, what is the measure of the sprinkler’s rotation in degrees?

1. Explain that since it takes 360 “one-degree turns” to rotate through a circle, 1/360 of a circle is a “one-degree angle”.
2. Measure an angle to the nearest whole number degrees using a protractor.
3. Draw points, lines, line segments, rays, right angles (exactly 90 degrees), acute angles (less than 90 degrees), obtuse angles (greater than 90 degrees and less than 180 degrees).

SCIENCE

1. Review how light travels in a straight path until interrupted by an object.
2. Review how light passes through other objects (transparent, translucent, opaque).
3. Review how light reflects, bends, and absorbs
4. Observe and describe some basic forms of energy, including light, heat, sound, electrical, and the energy of motion (mechanical).
5. Identify examples of these energy forms in their life and in the natural world.
6. Compare and contrast these types of energy.
7. Describe the requirements/components necessary for sound to be produced.
8. Investigate the production of sound (g., tuning forks, hollow tubes, vocal cords, or water bottles filled with different amounts of water).
9. Explain that sound is produced by vibrating objects.
10. Investigate variations in pitch (g., water bottle liquids, rulers, straws, stretched rubber bands).
11. Explain that pitch depends on the speed (fast and slow) an object vibrates and the measurements (size and length) of the object.

SOCIAL STUDIES

1. Outline the events and conflicts leading up to the first, second, and third Seminole wars
