PAGE 1 OF 5, ONE STORY, ONE NEW GROUP
JOIN
Two groups of objects being joined together to show the meaning of addition
ADDITION = "HOW MANY ALTOGETHER?"
You have some apples in one bowl and more in another, addition is the calm answer to: "If I put them together, how many in the big bowl?" It is the same work as counting on from the first group: you already trust the second group's size, then you keep counting. For whole numbers, 3 + 4 = 7 because 7 is where you land after the whole journey. The result has a name: the sum (or total).
🧺 SAME AS
Union of two groups with no overlap "adds" the counts, the idea behind the plus sign in real life.
