In first grade, addition is all about putting things together. When we 'add,' we're finding the total number of items when we combine two or more groups. Think of it like having a few toys and getting more – addition tells you how many you have in all! We use the plus sign (+) to show that we're adding. For example, $2 + 3$ means we're adding 2 and 3 together.
Addition helps us solve everyday problems, like figuring out how many cookies we have if someone gives us extra. The answer to an addition problem is called the 'sum'.
