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

4.G.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.

4.G.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.

 Students can draw and identify points, line, line segments, and rays in two dimensional figures

Can group shapes based on the types of lines they have

Can group shapes based on the types of angles they have.

Can identify a line of symmetry in a variety of figures.

Can draw a line (s) of symmetry

Geometric measurement: understand concepts of angle and measure angles.
4. MD. 6 - Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

4. MD. 7 - Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure.

4. MD. 5 - Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:

a. An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles.

b. An angle that turns through n one-degree angles is said to have an angle measure of n degrees.

 Students can use a protractor to measure and draw angles
