Twenty adding facts with totals from 11 to 20. About two thirds add two single digits and cross ten, such as 8 + 5, which is where making ten helps: 8 + 5 is 8 + 2 + 3. The rest add a teen number and some ones, such as 13 + 4. Each answer goes in a heart. It is the first grade standard for adding within 20, dressed up for February.
