Addition is one of the most fundamental mathematical operations and forms the building block for all higher-level math. When we add numbers together, we're combining quantities to find a total. This skill is used constantly in everyday life, from calculating grocery bills to managing time.

Learning addition starts with understanding that numbers represent quantities. When children first learn to add, they often use physical objects or their fingers to count. As they progress, they develop mental math strategies that allow them to add quickly and accurately without counting each item.

There are several strategies that help with addition. The "counting on" strategy involves starting with the larger number and counting up. For example, to solve 7 + 3, start at 7 and count: 8, 9, 10. Another useful strategy is "making ten" — finding number pairs that add to 10, then adding any remaining amount.

Practice is essential for building addition fluency. The more students practice, the more automatic their recall becomes. This automaticity frees up mental energy for more complex problem-solving. Regular practice with varied problem types helps solidify understanding and builds confidence.
