Not only does this foldable provide all variations of the formula involving Mass, Volume and Density, but the foldout part already has the definitions filled in for you. A GREAT piece to add into a journal to help students with vocabulary and with the understanding of the mathematics involved in calculating density.
Applet informally illustrates to the student that the sum of the measures of the interior angles of any quadrilateral is 360 degrees, and that the sum of the measures of the exterior angles of any quadrilateral is 360 degrees. This applet is a revision of the one found at http://tube.geogebra.org/m/1878165. It was revised in order to help students develop the formula for the sum of the measures of the interior angles of any n-gon = 180(n - 2).
