I really loved this lesson! I printed out the labeled animal picture cards with blank boxes from The Itty-Bitty Bookworm and we had magnetic letters that we put in the correct boxes.
Since Caden is only 2 1/2 years old and the Bo's Curriculum from The Itty-Bitty Bookworm is for ages 3-5 years old I am going to modify this lesson for our next use (here is one of the worksheets the rest are posted on my scribd). Instead of the words being under the picture I am going to place them right above the boxes so he can match them. He had a hard time understanding the order of were to place the correct letter in the correct box. Overall he loved this activity. We did it about 3 times yesterday and 2 today.
