In sixth grade, students begin by exploring positive and negative integers on the number line, including prime numbers and introductory number theory. Students develop nuanced skills to work with challenging word problems, connecting fractions, ratio, rates and percents. Students learn to simplify algebraic expressions, solve one-step algebraic equations through balancing, and graph linear equations on the coordinate plane. Students continue their study of geometry with a deeper exploration of two-dimensional shapes and three-dimensional solids, including the area and circumference of a circle as well as composite geometric figures. The geometry curriculum uses one-step equations to reinforce the algebraic foundation built earlier. Students end the year with a comprehensive statistics unit, covering methods of data collection and the measures of central tendency.
