I don't think Peter's site lists those exercises that are not in the mission skills (counted towards the WoM).

Exercises like:

https://www.khanacademy.org/math/early-math/cc-early-math-place-value-topic/cc-early-math-tens/e/tens-and-ones

and all of the Multiply by 2, 3, 4, ....

https://www.khanacademy.org/math/cc-third-grade-math/cc-3rd-mult-div-topic/cc-third-grade-applying-mult-div/e/multiplying-by-2

and all of the Divide by 2, 3, 4, .....

https://www.khanacademy.org/math/cc-third-grade-math/cc-3rd-mult-div-topic/cc-third-grade-applying-mult-div/e/dividing-by-2

as some examples.

and yes, I agree, these exercises can still be used to achieve speed badges but they can not be mastered.
