**Tim Bottman**on Mar 11, 2014Near doubles are also called the “doubles-plus-one” facts and include all combinations where one addend is one more than the other. There are 18 of these facts. When students realize that these are facts that have addends with a difference of 1 (1 + 2), (3+ 4), (5 + 6) etc. they simply double the smaller addend and add 1.

**Tim Bottman**on Mar 11, 2014This strategy is used for facts that have a 1 or a 2 as one of it’s addends (example: 8 + 2). Out of the 100 addition facts students will learn, 36 fall under the one-more-than and two-more-than facts. In these situations, students simply count up 1 or 2 from the greatest addend. This should be the only situation where students “count” to find their answer.

**Tim Bottman**on Mar 11, 2014There are only 15 remaining facts to learn after the previous facts have been mastered. Use other known facts to help find the more difficult facts.

**Tim Bottman**on Mar 11, 2014This set of facts includes all the turn-around facts for facts of one more than and two more than. The answers to all of these facts will be 1 or 2. Students should use their knowledge of addition and fact families to solve these facts. For example, when solving 7-2, the student should ask, “What plus 2 equals 7?”.
