- Informally explore angles as an attribute of two-dimensional figures. Identify and classify angles as acute, right, obtuse, straight or reflex.
- Estimate angle measures. Using a protractor, measure angles in whole-number degrees and draw angles of specified measure in whole-number degrees. Demonstrate that angle measure is additive.
- Solve real-world and mathematical problems involving unknown whole-number angle measures. Write an equation to represent the unknown.
- Compare and contrast the major stages in the life cycles of Florida plants and animals, such as those that undergo complete and incomplete metamorphosis, and flowering and nonflowering and seed-bearing plants.
The student will:
- Understand, identify, and draw angles.
- Measure angles using degrees.
- Use fractional parts of a circle to measure angles.
- Explain how degrees are related to fractional parts of a circle.
- Use benchmark angles to estimate the measures of angles.
- Use a protractor to draw and measure an angle.
- Write an equation to find an unknown angle measure.
- Review that all living things have a life cycle.
- Review the ways plants can reproduce – flowering and non-flowering (with cones and spores)
- Explore life cycles of various plants found in Florida (e.g., orange tree, pine tree, hibiscus).
- Diagram the major stages in the life cycles of plants (seed, seedling, mature plant, flower or cone).
- Compare the major stages in the life cycles of Florida plants, both flowering and nonflowering seed-bearing plants (e.g., daisies and pine trees).
- Explore life cycles of various animals living in Florida.
- Describe complete metamorphosis (4 stages) using animals that undergo this change (e.g., butterflies, frogs, flies, ants).
- Describe incomplete metamorphosis (3 stages) using animals that undergo this change (e.g., grasshoppers, cockroaches, dragonflies).
- Compare and contrast differences in body structures of the different stages (egg, larva, pupa, adult, nymph).
- Differentiate between the major stages in life cycles of Florida animals including, but not limited to, those that undergo incomplete and complete metamorphosis.
