One activity you might want to consider is to glue orange ovals around a piece of construction paper to make a border and color the template O's orange as well

• Print the template and color in the O o.  Point out to the child which is the capital O and which is the lowercase.
    
• Ask what shape the letter O is -- it's an oval.
    
• Fold a piece of orange construction paper in half a couple of times and roughly cut out some oval shapes (they don't have to be perfect)
    
• Meanwhile, have the child color the template pieces with an orange crayon.
    
• On a separate piece of construction paper (we used white), glue the orange ovals around to make a frame.
    
• Cut out the O's and glue them to the center of the frame.
    
• Point out that orange and oval start with the letter o.
          

• Whenever I do these projects with Kaitlyn, I get to draw pictures of words that start with the letter and then she gets to color them.  Don't stress about your drawing skills... the kids will love watching you draw!  Letter O words I drew were a picture of an ostrich, a wise old owl, an orange slice, an ox, an old oak tree, and an ogre (Kaitlyn likes the Shrek movie *grin*)
