My school district adopted Investigations as our Math program this school year and we LOVE it! One of our recent units was on measurement using non-standard units. Our favorite activity was measuring the feet of many people we know and love from around the school. I spent an afternoon tracing the feet of people such as our principal, the coaches, our art teacher, the Kindergarten teachers and even my sweet husband (who loves my K friends by the way). The next day, we measured the feet and tracked our data. We found that my husband had the biggest feet and one of our K teachers had the smallest.
