Students create a line plot [with dots] to represent stacks of coins. Then rearrange the dots to form different line plots and watch what happens to the mean.

This lesson teaches students about inverse variation by exploring the relationship between the heights of a fixed amount of water poured into cylindrical containers of different sizes as compared to the area of the containers' bases.

During this video students will build an understanding of and recognize the criteria that make something “matter”. Demonstrations of the differences that exist between solids, liquids, and gases will be shared.

This lesson will teach students to factor trinomial expressions of the form x^2 + bx + c. Students will use algebra tiles to identify the binomial factors and the graphing calculator to verify the result. In addition, students will identify the x-intercepts and y-intercepts of each trinomial function and explore relationships between the trinomial x^2 + bx + c and its factored form (x + m)(x + n).
