Find the Area of a Rectangle by Counting Columns and Rows
When finding the area of rectangles, understanding the arrangement of unit squares in rows and columns is essential. The visual models included in this instructional video help to clearly define rows and columns for young mathematicians, using multiple examples to model how they are used to skip count when determining the area of a rectangles.

Solar Kit Lesson #13 Solarize a Toy
Students work in teams they select a low-power toy, game, or electrical deive to "solarize," or convert to solar power. They determine the operating voltage of their chosen device and design a solar array to provide this level of voltage. Pupils determine a series of conditions under which they test their toy's performance and, if needed, adjust the size of their solar array to provide more current.
