Most of this section is review of prior standards taught in earlier grades. However, there is much overlap between the earlier grade standards and the high school geometry standards.

High School Common Core:

• CCSS.MATH.CONTENT.HSG.CO.A.1: Know precise definitions of angle, circle, perpendicular line, parallel line, and line segment, based on the undefined notions of point, line, distance along a line, and distance around a circular arc.

Grade 4 Common Core:

• CCSS.MATH.CONTENT.4.MD.C.6: Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

• CCSS.MATH.CONTENT.4.MD.C.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.

This unit is 99% review of prior grades starting with 4th grade. You have been practicing the essential components of geometry for last six years. In 8th grade you were introduced to the concepts of congruency and similarity. By 9th grade you have been evaluating expressions and solving linear equations with variables on both sides. You will need all these algebra and geometry skills as the foundations of this course.

Below are the common core standards first introduced in grade 4 and which we will be revisiting in Unit 1 of High School Geometry. However, if you are interested in seeing the progression of standards across the grade then click here.

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

CCLS - Math: 4.MD.6: Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

CCLS - Math: 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.
