&quot;GIANT SPONGE - NEW AXIOM&quot; Sand &amp; Water Tables. &quot;What is a giant sponge? It is a piece of foam cut from a foam mattress to fit into the sensory table ... Because the children can make impressions on the sponge, they can also use the utensils provided to make imprints ... This year for the first time the children started to use the surface of the Giant Sponge to draw things with their fingers.&quot; Originally Pinned by Alec Duncan of http://childsplaymusic.com.au/
