thinking about measurement in kindergarten

Posted on: May 24th, 2016 by jnovakowski

I was invited into Denise Tong Vargas’ kindergarten class at Dixon Elementary to look at ways to present mathematical provocations to students at this age level as well as how to integrate technology use as a way to document learning.

For our first time together, I asked the students to share what they knew about measuring. I then did a little demonstration with matryoshka dolls which the students were fascinate with. We compared their height and ordered them from tallest to shortest. We talked about the importance of using specific mathematical language like long, tall, short instead of a general term like “big”. We talked about how when we are comparing two objects directly that we need to “line them up” or use a baseline for accurate comparison. The students were then challenged to find something in the classroom and compare and measure it in different ways.

As we came together at the end of their investigation time, as a way to share the students’ ¬†experiences and consolidate students’ thinking, we co-created two pic-collages using photographs I had taken using iPad technology, focusing on the concepts of baseline and units.

On my second visit to the class, Denise and the students settled in with their regular morning routine and then I talked to the students for a short time about the big idea that we were going to focus on – comparing and ordering objects and how we might use mathematical ideas and measuring tools to help us investigate this. I had set up three provocations on tables, adding to the one that Denise and her students had been investigating already.

And I added another onto the carpet area involving containers and cylinders to ¬†provoke students’ thinking about measuring curved surfaces and measuring capacity/volume.

There was high engagement amongst the students and many of the children stuck with one set of materials or provocations while others moved around. It was interesting listening to them play with the language – second tallest, “mediumest”, third shortest, etc., play with the materials and play with mathematical ideas.

I must say that there is something to be said for unique and “fresh” materials that engages students and helps bridge school and the world outside of the classroom. By using toys and materials (like ribbons and pinecones) that they might find outside or at home, the students can see that they can be measuring wherever they are – not only if they have a ruler or Unifix cubes!

Some new pic collages were created to help consolidate the students’ learning and to focus on the big ideas involved with measuring.

I am looking forward to checking in on Mrs. TV’s classroom blog to see what other measuring experiences the students have.
