- Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself. For example, given the rule “Add 3” and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.
- Recognize angle measure 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. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure.
- Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
- ·Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.
- Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.
- Explain that although characteristics of plants and animals are inherited, some characteristics can be affected by the environment.
- Recognize that animal behaviors may be shaped by heredity and learning.
- Generate a number or shape pattern that follows a given one- or two-step rule.
- Identify features in number or shape patterns after following a given one- or two-step rule.
- 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 degrees), acute angles (less than 90 degrees), obtuse angles (greater than 90 degrees and less than 180 degrees), and perpendicular and parallel lines.
- Identify points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines in two-dimensional shapes.
- classify two-dimensional shapes into the following categories: those with parallel lines, those with perpendicular lines, those with both parallel and perpendicular lines, those with no parallel or perpendicular lines.
- Classify two-dimensional shapes into categories based on the presence or absence of acute, obtuse, or right angles.
- Recognize that right triangles form a category of triangles and identify triangles that fit in this category.
- Explain line symmetry and identify figures that have line symmetry (e.g., fold a figure or draw a line so it has two parts that match exactly).
- Draw lines of symmetry in both regular and non-regular polygons.
- 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 in both positive and negative ways (e.g., fires, humans, pollution).
- Explain that some characteristics (traits) of animals are inherited by offspring from parents (e.g., freckles, height, dimples, eye color).
- Explain that some characteristics (traits) of animals are learned/acquired by the environment (e.g., hair color and length, playing an instrument, reading).
- Explain that environmental factors such as climate, disease, light, temperature, predator-prey relationships, and food supply, can affect some characteristics of organisms.
- Give examples of how animal behaviors may be shaped by heredity or learning.
- instinctive/inherited behaviors: hibernation, migration, hunting, protecting young, courtship, grooming, verbal communication, fighting, etc.
- learned behaviors: using tools, language, hunting, playing sports, writing, etc.
- Form conclusions that many animal behaviors are a combination of both heredity and learning.
- Differentiate between learned/acquired behaviors and inherited/innate behaviors.
