My students are learning how to measure objects and distances using non-standard units. Before we practiced measuring, we discussed why we need to know how to measure and also made a list of non-standard units that we could use in the classroom. Then, as a class, we demonstrated the many WRONG ways to measure an object.
They also had a chance to practice measuring individually at their seats. The students measured any item in their desk - scissors, pencil box, highlighter, folders...etc. We held a discussion on why some friends needed a different number of paperclips to measure their highlighter. This was a great way to see who really understood the concept and who didn't. Some kids had a hard time understanding that not everyone's highlighter was the same size! The scissors were a good example to show that the units do no have to touch the object. Some kids wanted to outline the scissors with their paperclips.
On day 2, we discussed the non-standard unit of 'kid steps'. The students found pieces of masking tape on the classroom floor...if you teach first grade, you know how exciting something like this can be for them! They LOVED it! Each piece of tape was lettered A-H. The students were to go around and practice measuring each piece of tape using 'kid steps'. They were to record their findings on their record sheet and compare the pieces of tape. When they were finished, we came together and shared our measurements. (*Activity from Math Investigations)
I love teamwork!!!!
For homework, the students were to trace and cut out an outline of their foot and hand. They were to use outlines to measure objects in their home and record their measurements. I'll post their findings when they bring them back to school. Stay tuned!
