Learning the "5 and some more" number combinations will help first grade students master a chunk of their addition and subtraction facts within 10. For example, if a student knows 5+3, they can use the understanding of that combination to also become automatic with 3+5, 8-5, and 8-3. Knowing these different combinations is not only important for the mastery of math facts, but also for success in later grades with higher level concepts and strategies.

These slides have various representations to help students learn the "5 and some more" combinations. Show your child one slide at a time and have him tell you the facts he sees, such as 5+3 and 3+5. Once your child knows these addition combinations, you can challenge him further by asking for the related subtraction facts. For example, when shown the image with 5 dots and 3 dots, a student might start with the total of 8 dots, cover up 5, see that 3 are left, and say, 8-5=3. Your child could also visualize the other part being taken away and say, 8-3=5.
