Learning how to add
There are a number of ways to approach addition.
Combining sets
One of the most common ways to teach/learn addition is by combining sets. To combine sets, we first need to know how to count. Once we know how to count, combining sets (at least smaller ones) becomes relatively simple. Start with small numbers of objects that we can easily count to; this can be objects drawn on a page, or any object in real life such as a marble, peanut, or shapes on a page. To add the numbers in both sets, we just need to count the number of objects in each set, then combine them.
