Mystery Letters is a fun activity to practice letter recognition. What you do is write letters on paper with a white crayon. Then have your toddler use water colors to paint the paper. And watch to see their excitement! Jake thought this activity was "Magic!" He really enjoyed painting to find the letter. The papers were stacked in alphabetical order. I did not expect him to finish them all in one sitting but he did finish in one day. He took a little break to play but came back to finish up. We will use the papers to spell his name and other common words. As well as putting the letters in order.
