Grade 4: Chapter 10 - Two-Dimensional Figures

Chapter Essential Question:How can you draw and identify lines and angles, and how can you classify shapes?

Before
(Grade 3) / Chapter Nine Standards
Grade 4 / After
(Grade 5)
Reason with shapes and their attributes. (3.G.1)
Solve problems involving the four operations, and identify and explain patterns in arithmetic. (3.OA.9) / Operations and Algebraic Thinking 5: 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.
  • I can use the strategy act it out to solve pattern problems.
/ Classify two-dimensional figures into categories based on their properties. (5.G.3, 5.G.4)
Analyze patterns and relationships. (5.OA.3)
Geometry 1: Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
  • I can identify and draw points, lines, line segments, rays and angles.
  • I can identify and draw parallel lines and perpendicular lines.

Geometry 2: 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.
  • I can classify triangles by the size of their angles. (Also 4.G.1)
  • I can sort and classify quadrilaterals.

Geometry 3: 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.
  • I can determine whether a figure has a line of symmetry.
  • I can identify and draw lines of symmetry in two-dimensional figures.

Each day the math block will begin with 15 minutes of Daily Math Review and Mental Math. The focus of DMR should be either prerequisite standard skills or previous chapter concepts that were not mastered. The focus of mental math should be based on the current Chapter’s skills and concepts. Adjust the amount of questions in DMR and MM to fit into the 15 minute time block.

Suggested Chapter Pacing

All lessons are paced for one day, unless otherwise indicated. Teachers may adjust to meet students’ needs.
