Why do we measure? There are many different reasons why we need to
measure. Measuring helps us make sure that the things we make, come out
as planned. When baking you need to measure the amount of Ingredients In
a recipe. A shop uses scales to weigh the food they sell. They need to know
how heavy or light something Is. A seamstress needs to measure the length of
fabric she needs to make clothing. She will use a measuring tape to make sure
everything Is the right size. A police officer measures the speed of a car to make
sure vehicles are not speeding. And you may be wondering and looking at your
watch to find out how long It will be until your lesson finishes.

Whether we need to measure weight, time, distance, size, temperature or
calories, we will need to use the correct measuring tools and the various
methods associated with them.
