We have recently started measuring using standard units of measure. In order to help the children understand why it is important to have units of measure we have read the story How Big Is A Foot. In this story, no one can get the measurements correct because they all have different sized feet. This leads us in to the discussion of why we have to have standard units.
This week we decided to measure twizzlers using inches. We have been using rulers to draw line segments and measure, so this was a great reminder of how to do this.
First the students were given a length to measure. I reminded them that you have to start in the same place as everyone else in order to get the correct answer and we discussed where you start when you look at a ruler. Children always seem to get confused as to whether to start at the number 1 or the end, so this was a great way for us to reinforce that concept.
After students were given the length that they needed to measure, they were asked to use plastic knives to cut their twizzlers to that particular size. This was a great way for us to talk about safety when using knives and how to use them.
Once we finished cutting several different lengths of twizzlers, I asked the students to put them in order from the longest to the shortest.
Who knew that you could cover so much with just a few twizzlers?!
