- 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.
- 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.
- 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.
- 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.
- Create a line plot to display measurement data including fraction units of halves, quarters, and eighths.
- Use the measurement data on a line plot to solve problems involving the addition and subtraction of fractions with like denominators.
- 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).
- 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?
- 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.
- 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).
- Review how light travels in a straight path until interrupted by an object.
- Review how light passes through other objects (transparent, translucent, opaque).
- Review how light reflects, bends, and absorbs
- Observe and describe some basic forms of energy, including light, heat, sound, electrical, and the energy of motion (mechanical).
- Identify examples of these energy forms in their life and in the natural world.
- Compare and contrast these types of energy.
- Describe the requirements/components necessary for sound to be produced.
- Investigate the production of sound (g., tuning forks, hollow tubes, vocal cords, or water bottles filled with different amounts of water).
- Explain that sound is produced by vibrating objects.
- Investigate variations in pitch (g., water bottle liquids, rulers, straws, stretched rubber bands).
- Explain that pitch depends on the speed (fast and slow) an object vibrates and the measurements (size and length) of the object.
- Outline Florida’s economic state during the 1920s.
- Describe the causes and effects of the land boom and bust.(An example may include, but is not limited to, land speculation)
