Not sure what you mean by counting cubes? Are you suggesting connecting cubes? Maybe give students access to connecting cubes and ask them create a visual number lines. Let them determine the colour order to visualize a base ten system.

Later, I we can explore our rulers. They can ‘mod’ modify their ruler to visualize a number line. (mod with highlighting each ten with a yellow jiffy ect…)
