Being able to measure the world around us is a life skill. When we cook, build things, and buy shoes we need to understand measurements. When scientists send spacecraft to the moon or perform experiments they need to measure. When artists paint or create sculptures they need to measure. Think about all the things you do every day and you will see how many ways you need to know how to measure. We measure length, weight, capacity, volume, temperature, and time. There is an entire webpage for learning about time on this site.
