Free interactive math game: Multiples Between — Count in range. Part of the Divisibility & Numbers category on MathKite.
Taken from the generator that powers this exercise. A fresh set appears every time the page is opened, and the printable worksheet holds ten of them.
Counting multiples that fall strictly between two numbers.
Find the first multiple above the lower bound and the last one below the upper bound, then count the steps between them.
Multiples of 6 strictly between 29 and 64 run 30, 36, 42, 48, 54 and 60 — six of them.
Including a boundary. Strictly between excludes both endpoints even when they are multiples themselves.
