What does this generator do?
The generator writes two two-digit numbers one above the other. The student adds them and fills in the ones and tens digits of the answer. With regrouping, they can write a tiny carried "1" above the tens column.
How to use this exercise
Add the ones first. If they sum to more than 9, write a 1 above the tens column. Then add the tens, including the carried 1. Press "Check".
