A set of red rods in a beechwood display box.
Laying the rods in different combinations helps the child understand the relationship between the different sizes.
Placing the rods in the box supports the understanding of a regular step up in length.
Different combinations of rods fit into the spaces in the box.
The rods are not large enough to give a discernible weight difference between the sizes.
The lid is edged. Do not lift it by the lid as the box main body with the rods is not supported this way.
The box should be lifted with the hand underneath the box.
The lid fits snug and often forms a seal that needs a slight jerk movement to release.
