Reflections over the Axes
It is important for students to know what happens to the coordinates of points when they are reflected over the x-axis or the y-axis. This activity enables students to use Cabri Jr. to develop this understanding.https://education.ti.com/en/activity/detail/reflections-over-the-axes
Parallel Lines Cut by a Transversal
Students will develop and strengthen their knowledge about the angles formed when parallel lines are cut by a transversal. The measurement tool helps them discover the relationships between and among the various angles in the figure. Students will draw parallel lines, draw a transversal, and expl...https://education.ti.com/en/activity/detail/parallel-lines-cut-by-a-transversal_2
Population Mean: σ unknown
