Students will grasp and recall basic facts quickly with this outstanding program, plus learn strategies to ensure lasting mastery of addition. Learning the basic addition facts becomes an important part of the mathematics curriculum once students have a strong foundation in the prerequisite skills of counting, one-to-one correspondence, beginning number sense, and an awareness of the meaning of addition as the joining of two or more sets. The time at which this learning is undertaken varies from class to class, but traditionally the focus has been on rote memorization and repetitive practice as the “strategies” of choice.
