I don't know about all schools, but many start beginning readers out with little words that show up within bigger words. I came across my granddaughter's list from first grade and thought it might be fun to write some limericks using the words. Here we go!
(Today's base is "unt" and "in.")
Billy swung the bat with a grunt,
But he only managed to bunt.
He said with a grin
While scratching his chin
Next ball I hit you'll have to hunt.
