– Draw points, lines, line segments, rays, angles (right, obtuse, acute) and perpendicular/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.
– Recognize that animal behaviors may be shaped by heredity and learning.
The student will:
– Draw parallel and perpendicular lines.
– Identify angles (right, acute, obtuse), 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, those with none.
– 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 into this category.
– Explain line symmetry and identify figures that have line symmetry (folds that match exactly).
– Draw lines of symmetry in both regular and non-regular polygons.
– Give examples of how animal behaviors may be shaped by heredity or learning.
(inherited behaviors: instincts, hibernation, migration, hunting, protecting young, courtship, fighting, etc.)
(learned behaviors: using tools, language, hunting, playing sports, writing, etc.)
– Recognize that many animal behaviors are a combination of both heredity and learning (e.g. birds inherit the presence of feathers but must learn how to fly.)
