Children have been measuring using non standard units such as cubes, Duplo and paper clips. They discovered that it isn't a reliable way to measure. They had to make a monster that was exactly 1 metre tall, so they used metre sticks! They worked with their partners to create a scary monster! They had to check regularly and adapt their work. This time they discovered measuring using a metre stick was reliable! Their monsters were all the same size!
