Geometry:  I CAN...

Standard

Draw and identify lines and angles

Core Standard

G.1.Draw and identify lines and angles, and classify shapes by properties of their lines and angles. 1. Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

In Other Words

Tell and draw what each of the following are: point, line, line segment, ray, right angle, acute angle, obtuse angle, perpendicular lines, parallel lines. See amathsdictionforkids.com for help.

If Mastered

This mathisfun.com interactive can provide a challenge by giving more advanced information.

If Not Yet Mastered

Definitions of geomoetric terms are available at amathsdiconaryforkids.com

In addition to online activities, you can also make flashcards for each of the terms to practice.

Standard

Classify shapes based on their lines and angles

Core Standard

G.2.Draw and identify lines and angles, and classify shapes by properties of their lines and angles. 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.

In Other Words

Tell what a right triangle is. Explain what is the same and different about squares, rectangles and other quadrilaterals. For example, squares and rectangles both have four 90' angles, but a square also has all sides the same length. See amathsdictionaryforkids.com for more definitions.
