My 3 year old (not yet 3 1/2 ) has memorized most of "Zin zin zin, a Violin!". Granted, he's heard it a zillion times. Still, we were impressed. His favorite page is the bassoon page. He sounds so indignant and animated when he recites, "That lazy clown, the big bassoon! He plays low down, we're laughing soon. HEY GRUMPY!! Get your place in line!!"
It sounds kind of surreal to hear his sweet little voice reciting, "The stwings all soar, the weeds impwore, the brasses WOAR!..." or "thwoo its thwobbing double-weeding, oboe, please don't hesitate!" He loves that book.
We've been surprised to see him expressing crippling perfectionism recently. He's our non-quirky, happy-go-lucky kid, YK? He was playing with ds1's molecule set last night and he told dh, "I made a hexagon!!" And it actually did have six sides. He refused to let his older brother see it. He showed it to me but then immediately insisted on breaking it up once I saw it. He doesn't like anyone to see what he creates and he makes disparaging comments about stuff he makes or he says, "It's not done yet!!".
I can't think of too much my 5 year old has done recently. We've been reading about the periodic chart and about the different types of rocks. When I read about metamorphic rocks, he said, "That sounds like metamorphosis." He understands what I'm reading to him the first time I read it and he can talk intelligently about it. I enjoy reading to him. He's interested in some fun things.
Actually, I just thought of something. He made a 7 foot tall Lego tower, with dh helping to reach the high part for him. I was amazed that it was so stable. My son designed the base of the tower to consist of four pillars (about 8 inches tall) with a flat Lego base on top of them to build the rest of the tower from. He said he was looking at his Domino structures and that's when he realized that he could mimic the same structure with Legos to keep the base stable. He declared that it was like the Eiffel Tower. It was so cool!
