Topic B includes lessons 5-8. "Use a circular protractor to understand a 1-degree angle as 1/360 of a turn. Explore benchmark angles using the protractor. Use varied protractors to distinguish angle measure from length measurement. Measure and draw angles. Sketch given angle measures, and verify with a protractor. Identify and measure angles as turns and recognize them in various contexts." EngageNY (Currently, we do not have content for Lesson 6.)
Topic A includes lessons 1-4. "Identify and draw points, lines, line segments, rays, and angles. Recognize them in various contexts and familiar figures. Use right angles to determine whether angles are equal to, greater than, or less than right angles. Draw right, obtuse, and acute angles. Identify, define, and draw perpendicular lines. Identify, define, and draw Parallel lines." EngageNY
Topic_D_Two_dimensional_figures_and_symmetry
Topic D includes lessons 12-16. "Recognize lines of symmetry for given two-dimensional figures. Identify line-symmetric figures, and draw lines of symmetry. Analyze and classify triangles based on side length, angle measure, or both. Define and construct triangles from given criteria. Explore symmetry in triangles. Classify quadrilaterals based on parallel and perpendicular lines and the presence or absence of angles of a specified size. Reason about attributes to construct quadrilaterals on square or triangular grid paper." EngageNY (Currently, we do not have content for Lesson 16.)
Topic_C_Problem_solving_with_the_addition_of_angle_measures
Topic C includes lessons 9-11. "Decompose angles using pattern blocks. Use the addition of adjacent angle measures to solve problems using a symbol for the unknown angle measure." EngageNY (Currently, we do not have content for Lesson 9.)
