Addition and Subtraction Fact Strategy Posters
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.
These posters have proved useful in keeping the fact strategies front and center for second and third graders, long after daily math instruction has moved on to other topics. We invite you to print these out, use them in your classroom, and share your teaching tips and ideas with others on the Bridges Blog.
