Reflection: Intervention and Extension Volume as Additive - Section 2: Students Solving Volume


There is a challenge with working in small groups, and that is keeping all students working.  I have established a procedure for my students.  When they finish they can either help another student, work in their math workbooks, read, work on unfinished work, or extend an assignment from class. 

After a few students finished their worksheet they asked if they could work on an extension of this lesson, but they were not sure what they could do.  I asked, "Do you think you can find the volume of your cubby or the rectangular trash can?"  They quickly got a ruler and started measuring - I overheard them discussing if they should use inches or centimeters.  They settled for rounding to the nearest inch.
