If they don't dust it, I'll use it to teach sight words!  :oD

Due to budget cuts, there is no time for dusting!

Here are 2 sight words.  Next, I'll write some math equations!  :oD

You know what they say, "If they give you lemons, make lemonade."

Well, "If they give you dust, teach sight words!"   :)
