A few weeks ago, my class happened to be studying measurement at the same time as the Year 1/Year 2 class (Kindergarten & Grade 1), so we decided to get our two classes together.
The Year 1/ Year 2 students were measuring using non-standard units, so they measured a variety of items on the playground with their hands. Then, my Year 3/ Year 4 students measured with their hands as well, so that the kids could compare two different non-standard units.
Next, my students used their rulers to measure how tall the Year 1/ Year 2 students were. Since our numbers are so small, each of my Year 3/ Year 4 students was able to measure each of the Year 1/ Year 2 students. All of the measurements were NOT the same, so this gave us a great opportunity to talk about how to make our measurements standard.
I love opportunities to collaborate with other classes. Does your class ever work with students of another grade level?
