6 = 1 + 2 + 3

15 = 4 + 5 + 6

= 1 + 2 + 3 + 4 + 5

Consider the following modifications for learners who need additional support, including English learners and students with special needs:

- Discuss what consecutive means by giving an example and a non-example
- Discuss other terms students might not understand, such as "conjecture" and "look for patterns"
- Provide base 10 blocks for students to make the sums manipulatively

Ensure any modification does not reduce the cognitive demand of the task.
