Count 7 objects, add 2 and represent 7 + 2 = 9. Then remove 2 to return to 7. Compare two groups and decide which has more before writing symbols.
Combine counting, number order, shapes and early addition according to what the learner understands. Content and teaching order differ across school systems; these examples are practice choices, not an official curriculum equivalence.
Work through one example aloud before independent practice. To check 18 + 7 = 25, calculate 25 − 7. If a word problem asks about meters or coins, include that unit and check whether the answer fits the situation.
