These two lessons involved partitioning 5. I wasn't surprised that Reece understood this concept and that she knew all of these facts already. I decided to combine both lessons so she wouldn't get frustrated. I did make her show some of the problems on the abacus just so she would have practice with the concept of partitioning and how it looks and feels to do it with the abacus.
At the end of the lesson I told her that we'll be doing pennies and nickels tomorrow. She immediately balked - "I don't know which ones those are!" I smiled and said, "That's why there is a lesson on it. You're not supposed to know how to do it." It cracks me up. Riley is the same way: so frustrated and upset over a concept that I am preparing to teach, because she doesn't know it. Strange! LOL
As I was putting materials away, Reece said, "Wait! I know what a penny is - and it's worth one cent." "You're exactly right," I assured her. Then she walked away while muttering, "At least I know half of it!" ;)
