Learning Insight
Addition means combining two groups into one. When you add 2 + 2, you are joining a group of 2 objects with another group of 2 objects, giving you a total group of 4. This is the foundation of all arithmetic.Quick Tip
Doubles (like 2+2, 3+3, 4+4) are great facts to memorize first — they come up everywhere in math and make harder problems faster to solve.Common Mistake
A common early mistake is miscounting when counting on fingers, especially losing track of where you started. Always start counting UP from the first number, not including it in your count.
