Parallel Lines, Transversals, and Angles

# data[].attributes.attachment_link.description
In this activity, students explore the relationship among angles formed by a transversal and a system of two lines. In particular, they consider what happens when the two lines are parallel vs. when they are not.

The purpose of this activity is for students to solve inequalities with both positive and negative coefficients. Students solve inequalities to program how Shira the Sheep moves. This activity explores what happens when an inequality contains a negative coefficient and one strategy for determining the direction of the inequality.

In this delightful and challenging activity, students will transform lines so that the marbles go through the stars. Students will test their ideas by launching the marbles and will have a chance to revise before trying the next challenge.

At first glance, these are *just* rectangles, but many perimeters and areas have been strategically chosen. As students play, my hope is they will gain a deeper understanding of perimeter, area, and their independence.
