Learning Advantage 7657 Liter Cube

Great cube. The measurements are easy to read on the side. I love that it's clear and comes with a lid. I use it in my classroom when I work with my students on a challenge problem, "The Tilted Cube." The lid is decent and just leaks a little when I tilt my cube with water in it.

The absolute best way to teach metric! Get a flask with one liter of water, a scale, a set of brass weights. Kids never guess that a liter weighs one kilogram. And they are SURE you will spill over when pouring a liter of water in the box.
