This past week, I was asked to model a lesson in a grade 2 classroom using technology. They were just beginning non standard measurement so I decided to use the book, "Inch by Inch" by Leo Lionni. If you have not read this book, it is a wonderful story about a vulnerable inch worm that is about to be eaten but shows his predators that he is valuable by measuring them.
I read the story to the class and then I told them that we were going to do some measuring with worms. (No, not real worms, I bought rubber worms at the dollar store). We then talked about how to accurately measure an object. We specifically talked about how to line the worms up correctly making sure that they were not overlapping and making sure that we lined up the worms with the edge of the object we were measuring.
I then had volunteers come up and measure items with the worms. I wanted the students to have to do a bit of additional thinking so I posed this task for them to do:
