Learning Targets and Learning Criteria

MATH

1. Decompose a mixed number into a sum of fractions equal to 1 and a fraction less than 1 to find an equivalent fraction to replace the mixed number in an addition or subtraction situation.
2. Find equivalent sums or differences by converting fractions greater than 1 to mixed numbers by decomposing the fraction into a sum of fractions equal to 1 and fractions less than 1.
3. Add and subtract mixed numbers with like denominators using equivalent fractions, and/or by using properties of operations and the relationship between addition and subtraction.
4. Solve word problems involving addition and subtraction of fractions and mixed numbers with like denominators using visual fraction models (e., circular models, rectangular models, and number line models) and/or equations.
5. Create a line plot to display measurement data including fraction units of halves, quarters, and eighths.
6. Use the measurement data on a line plot to solve problems involving the addition and subtraction of fractions with like denominators.
7. 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).
8. 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.
• 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 Florida’s economic state during the 1920s.
2. Describe the causes and effects of the land boom and bust.(An example may include, but is not limited to, land speculation)
