4PAR3: Generate and analyze patterns, including those involving shapes, input/output diagrams, facors, multiples, prime numbers, and composite numbers.

4PAR3.1: Generate both number and shape patterns that follow a probided rule.

4PAR3.2: Use input-output rules, tables, and charts to represent and describe patterns, find relationships, and solve problems.

4GSR7: Investigate the concept of angles and angle measurement to estimate and measure angles.

4GSR7.1: Recognize angles as geometric shapes formed when two rays share a common endpoint. Draw right, acute, and obtuse angles based on the relationship of the angle measure to 90 degrees. b. An angle that turns through n one-degree angles is said to have an angle measure of n degrees. 

4GSR7.2: Measure angles in reference to a circle with the center at the common endpoint of two rays. Determine an angle's measure in relation to the 360 degrees in a circle though division or as a missing factor problem. 

4GSR8.1 Explore, investigate, and draw points, lines, line segments, rays, angles (right, obtuse, acute), perpendicular lines, parallel lines, and lines of symmetry. Identify these in two-dimensional figures. 

4GSR8.2: Classify, compare, and contrast polygons based on lines of symmetry, the presence or absence of parallel or perpendicular line segments, or the presence or absence of angles of a specified size and based on side lengths.
