Reflection: Joy Exploring Volume and Surface Area with Unifix Cubes - Section 3: Problem Solving


I ended up giving each student 20 cubes to work with.  It was my intention to give each student.  They could group their 10 with another students 10 to make the shapes in this section.  I noticed that most of the students wanted to have cubes in their own hands at all times.  I realized that I would also want to have my own set of cubes, even if I am working with a partner.  I have a lot of cubes - more than enough to give every student 20 - so why not?  What a few of the more competitive pairs ended up doing was raising to see who could build the block the fastest.  I had to remind these students that they are to find the surface area and volume too!
