Common Core For Grade 4

Videos, examples, solutions, and lessons to help Grade 4 students learn to draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

Common Core: 4.G.1

- I can identify and draw an example of point, line, line segment, ray, angle, parallel lines, and perpendicular lines.

**Lines, Line Segments, and Rays**

Difference between lines, line segments, and rays.

**Line Segments, Lines, and Rays**

A short explanation of line segments, lines, and rays, their labels, and the differences between them.

**4.G.1: Grade 4 Geometry**

Draw points, lines, line segments, rays, angles (right, acute & obtuse), and perpendicular and parallel lines. Identify these in two-dimensional shapes. This video relates to Common Core Standard 4.G.1. Students learn to identify right angles and straight angles as a point of reference and identify acute and obtuse angles using their definition.

**Acute Right and Obtuse Angles**

The difference between acute, obtuse and right angles.

Parallel sides are always the same distance apart and/or that parallel sides will never intersect if extended.

Perpendicular lines are lines that intersect at right angles.

The following activities are obtained from the Howard County Public School System.

Activity 1:

Look at the figures to the right. In each figure, highlight one pair of parallel sides.

Kelly is having trouble identifying whether two sides in a shape are parallel to each other. Explain how Kelly can decide if two sides in a figure are parallel.

Activity 2:

Look at the pentagon below.

Highlight two sides on the figure that are perpendicular.

Look at the angle inside the pentagon that is marked with the number 1. *Is the*

*angle acute, obtuse, or right?*
