Addition brings amounts together
When you add, two amounts combine to make a total. In 8 + 5, the numbers 8 and 5 are the addends and 13 is their sum.
To see why, split 5 into 2 and 3. Add 2 to 8 to make 10, then add the remaining 3 to reach 13. This is useful when a sum crosses ten.
Build confidence in small steps
Begin with familiar sums within 20, then move to tens and ones within 100 or hundreds within 1,000. Choose the range that fits your next step; each practice round builds gradually.
If a child counts every object again, ask what they already know about making ten. The focused round gives immediate feedback; the matching worksheet provides space to write the same kind of sums on paper.
