The first set of multiplication facts that should be learned are the 2’s facts. Facts that have 2 as a factor are equivalent to the addition doubles (e.g., 2 x 6 is equivalent to 6 + 6) and should already be known by students who know their addition facts.

This level includes a review of all subtraction facts plus 6 facts that have not been covered by any strategies.

This set of facts includes all the turn-around facts for the doubles + 1. Students should use their knowledge of addition and fact families to solve these facts. For example, when solving 11 - 6, the student should ask, “What plus 6 equals 11?”.

This set of facts includes all the turn-around facts for the inside doubles. Students should use their knowledge of addition and fact families to solve these facts. For example, when solving 8 - 5, the student should ask, “What plus 5 equals 8?”.
