Once students develop basic number sense, they can easily equate counting with basic math problems, such as figuring out that 1 less than 7 is 6. However, some students need practice combining their counting skills with their understanding of number sentences and math problems. This pack provides that practice by asking students to find "1 more than" and "1 less than" a series of numbers.
Write the number that is the answer to each of the number sentences.
What is 1 more than 8?
What is 1 less than 12?
