About the Math

When students count, they are focusing on counting objects not understanding the relationship that one number has to another. So when counting on and counting back, teachers need to be explicit in what that means. How is five related to four? It is one more than four. How is four related to three? it is one less than three. There is a difference in saying "two more than" from "comes two counts after". This understanding will help students as they become fluent with the facts to five and then ten (first grade).
If students understand one and two more and one and two less, this will help when learning the facts. Problems that ask students to use one/two more and one/two less help reinforce development of fluency. VandeWall - activities - page 171.
