About the single concrete cinder block with two hollow holes
A cinder block is a large, rectangular building block made of concrete. Two hollow holes through the middle make it lighter to lift and easier to stack than a solid block. Builders lay them in staggered rows to raise sturdy walls quickly. Use it in a shapes-and-building lesson, tracing the path around the block and its two holes.
