Today we started a new math unit on measurement, and I wanted to try something new to launch it. Before beginning, I decided to ask the kids what they already knew about measurement and what more they already wanted to know. We looked at the idea of creating mind maps (or concept maps) to lay out what we already knew, and then took off on an inquiry to find out what other areas of measurement we could find out about. The traditional stuff a lot of them already knew about included, measuring for length, width, height, perimeter, area, volume (mm, cm, m, km, mL, L etc...) Then all of a sudden I started seeing student discover words like capacity and temperature and dimensions, protractor, mass, distance, metric units and more and more.
After the concept mapping, students were asked to think of questions that they wanted answered about measurement (related to the key concept questions if possible) . We will hopefully get a chance to inquire into some of these in between meeting our curriculum goals.
