Bridges Blog Archive for October 2009

Several years ago, Kim Hornbeck, a teacher and math coach in Casper, Wyoming, developed a set of posters to help her students remember the addition and subtraction fact strategies taught in Bridges, Grades 2 and 3. Each of these 8 1/2″ x 11″ posters describes and illustrates a strategy such as doubles, neighbors, fast 9’s, take-away 10’s, and so on. Kim has agreed to share the posters with the larger Bridges community, so we offer them to you here.
