9 is nearly ten. It only needs 1 more.
Step 1: Let's Learn
Read it, or press Listen and follow the words.
Take one from the other number
For 9 + 5, take 1 from the 5. Now it is 10 + 4.
First ten
The rest
9 needs 1 more to make ten. Take 1 from the 5.
First number
Second number
10 + 4 is easy. You do not have to count at all.
Why nine needs exactly one
Nine is one short of ten. Moving one across fills it exactly, and the other number loses exactly one. Nothing is created or lost.
Watch the total stay still
9 + 5 becomes 10 + 4. Both are 14. You did not change the amount, only the way it is arranged.
Step 2: Try It Yourself
Move the counter and watch the sum change shape.
