For whatever reason, Anna’s favorite episode in Sid the Science Kid lately has been the one about measuring sizes (I think it’s called The Whale Tale and it belongs to the first 5-episode unit about Science Tools). While she was watching it yet again, I organized her a measurement math box with a ruler, a measurement tape and a tailor tape. She was very happy to play with these tools for a while. I asked her to predict what will happen if she measures the box with three different measurement devices? Will they show the same number? She thought for a little bit and then predicted that yes, they will. Then she tested it, but tailor tape was a little hard for her to handle, and it was something that she didn’t see before. We talked how it is used and when and measured our heads and our hips. Once she had her fun for a couple of days with standard measuring tools (and in the end she used the ruler more or less correctly), I replaced them with Lego blocks and a big block to talk about non-standard measurements. It didn’t go over too well. Anna did measure the length of the block, but then informed me that Lego belongs upstairs and she wants to head there pronto, put them where they belong and then play with them. Still we all had fun and “inch by inch” we learn more about how size and distance are measured.
