My Kindergartner won't count to 10. How can I get him to?

Stop getting agravated. He knows his numbers he's just sick and tired of having to recite them over and over and over. Give the kid a break. Even my daughter who has an IQ of 165 refused to say the letter J when reciting the alphabet on her own. She could do the "ABC Song" forwards and backwards perfectly, she could say the alphabet with her preschool cl but when asked to say the alphabet on her own she always left out the letter J. One day the Preschool teacher asked her why she was so good at it with the cl and when singing the song but didn't say the letter J when she was by her self. Her answer was very simple and logical. "I don't like the letter J".
