### A Quick Reminder On Addition and Subtraction

When we first begin learning math, we learn our numbers (numeracy). We begin with their names and then we learn how to count them in sequential order. The next step is to learn addition which is simply counting forward. If you go in with this mindset for addition, it will be simple for you. When presented with the problem 7 + 5, it plainly means that we are starting at 7 and need to count up 5 from there. We can do it in our mind as: 7, 8, 9, 10, 11, 12. It helps to see this on a numbers line. As you practice this, you will quickly master skip counting. We can use this same strategy to work with subtraction. See if you are picking up what I am putting down with the example problem: 16 – 7. This just tells us to count 7 down from 16 or 16, 15, 14, 13, 12, 11, 10, 9. As you progress with this skill, you will start to memorize these addition and subtraction problems, but this is a good starting point for you. This series of worksheets cover values that are undergoing subtraction or addition to value that is twenty or less. You can apply all the techniques that we explored here until you get better with this skill.
