4th Grade Geometry

4th Grade Math Common Core Geometry

The Common Core Math Standards have been adopted as a set of guidelines for the teaching, learning, and understanding of mathematics in the United States.

In the third grade, students usually learn about basic geometric shapes and ideas like points, lines, line segments, angles, and planes. They might also learn about symmetry, similarity, and simple changes like translation, rotation, and reflection.

Some specific things that students in the third grade might learn about are:

  • Draw different types of lines and angles; obtuse, acute, right
  • Categorize different shapes by the types of angles they have.
  • Learn about symmetry in two-dimensional shapes.

CCSS.MATH.CONTENT.4.G.A.1| Draw and identify lines and angles, and classify shapes by properties of their lines and angles.

Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

Standards: 4.G.A.1:

CCSS.MATH.CONTENT.4.G.A.2| Draw and identify lines and angles, and classify shapes by properties of their lines and angles.

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.

Standards: 4.G.A.2:

CCSS.MATH.CONTENT.4.G.A.3| Draw and identify lines and angles, and classify shapes by properties of their lines and angles.

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.
