TX. 111. 6. Grade 4, Adopted 2012.
4.6. Geometry and measurement. The student applies mathematical process standards to analyze geometric attributes in order to develop generalizations about their properties. The student is expected to:
4.6 (A) Identify points, lines, line segments, rays, angles, and perpendicular and parallel lines.
4.7. Geometry and measurement. The student applies mathematical process standards to solve problems involving angles less than or equal to 180 degrees. The student is expected to:
4.7 (B) Illustrate degrees as the units used to measure an angle, where 1/360 of any circle is one degree and an angle that "cuts" n/360 out of any circle whose center is at the angle's vertex has a measure of n degrees. Angle measures are limited to whole numbers.
4.7 (C) Determine the approximate measures of angles in degrees to the nearest whole number using a protractor.
