Use dance to help learners conceptualize line segments, rays, lines, and planes. They choreograph dances that show dimensional space. Dancers start by pondering space, point, and lines as the teacher draws them in the air. Each movement they make is described in mathematical terminology as it relates to points, segments, rays, planes, and lines.

Lines, Line Segments, Rays, and Angles - Practice 15.1
Is it a line, line segment, ray, or angle? Identifying geometric figures is the focus. In addition to identification, learners recognize right angles or tell if an angle is less than or greater than a right angle. They tell if lines are parallel, intersecting, or perpendicular, and solve word problems.

Integers! It All Adds Up!
Young mathematicians add integers using a number line. They create a number line on their Ti-73 calculator. Furthermore, they will add integers on the number line using vectors and addition expressions. Finally, these mathematicians will evaluate real-world examples that compare the values of integers.
