Building number sense step by step

Number sense grows in order. Children first learn that numbers have a fixed sequence, which is what missing number practice protects. Then they learn that two groups can combine into one bigger group, which is addition. Subtraction completes the picture by showing that a group can be split again, and that the two operations undo each other. If a learner struggles with subtraction, the most helpful step is usually more addition practice with the same numbers, because every addition fact is also a subtraction fact waiting to be reversed.
