Counting Rods
Ten rods from one unit to ten, each one exactly as long as the number it stands for, so five and five make ten in the hand before it makes ten on paper.
Ten rods, in the base. 
Five and five, in the hand. 
300 mm, which is a big number.

Every number here is off the drawing rather than off a finished toy. The one rule that is not a target is the 40 mm floor on any part, which clears the small-parts cylinder and does not move.
They stack into their own base for tidying.
Why it is shaped like that
Length is the only way a young child can see that eight is more than seven without counting it twice.
Living with it
- The single unit rod is 30 mm and clears the small-parts cylinder.
- The base holds all ten, so a missing rod shows at a glance and gets found.

Related skill, different task. Length rods support length composition. The bead snake depends on countable units and exchanges; unmarked rods are not a direct substitute.
- Place Value Bead Bank Game
Related skill, different task. Rods can represent lengths up to ten. Hundreds, thousands and place-value exchanges need the bank materials.
