Building Powerful Numeracy for Middle and High School Students

The modeling of reasoning strategies on the open number line, the open array, and the ratio table allows students to solve problems in their own way and compare different strategies with the rest of the class. The lesson plans and activities in this teaching resource help students build mental pictures of additive, subtractive, multiplicative and proportional relationships that can later be applied to higher mathematics Annotation 穢2011 Book News, Inc., Portland, OR (booknews.com)
