Math Olympiad does seem pretty cool. He hasn't done it before but is on the 4th grade team this year. They met for the first time yesterday, but gave them problems to work on throughout the week. I like that it is not your typical math and is more outside the box and problem-solving from what I have seen so far. I am looking forward to seeing him have to actually think and not just know it right away. I think this will be good for him, and also to have him get some wrong at times. I really am hopeful it is a challenge to him. I am not ashamed to admit that the calcudoku's he brought home yesterday from enrichment were a challenge to me...but surprisingly were not really too much of one for him. But I do think the olympiad problems will be. And if not, they can move him to the 5th grade team. : ) Hope you have a great year!
