Students also contextualize by writing arithmetic and geometric sequences to model real-world situations. Decontextualization is emphasized in the course when students use structure to solve equations related to these models, graph functions, and translate between multiple representations of equations and expressions. 3. x marks the spot that might confuse pre-algebra students. These materials help students understand how to solve basic algebra equations. Even though solving for x is a more advanced math skill, we’ve included worksheets that teach basic algebra equations through coloring because every student loves to color even if they don’t love algebra. The heavy vertical lines on the tenths squares show 10 tenths in one whole square, and these lines together with the lighter horizontal lines divide the square into hundredths. The number of full vertical columns is the number of tenths for the decimal, and a partially shaded column shows the additional number of hundredths.

• 3 types of interruptYou can also add text, 2-D math, various shapes, or free form drawing to a 2-D plot using a set of drawing tools. Typesetting for 3-D plots provides the ability to use typeset mathematics and text in titles, captions, axis labels and text objects, as well as the ability to edit them in place.
