Since students must demonstrate their computational skills on Iowa Tests as well as other forms of assessments, I have tried to give my students the opportunity to practice these skills while at the same time encourage mathematical thinking. For example, as part of morning work(work students do while I take attendance or lunch count), I frequently put 3 or 4 multiplication, division, subtraction, or addition problems on the board. I ask students to estimate the answer, write a real world situation which would require the solving of this problem, and for a challenge try to find the answer two ways. Students keep their work in a log book so they have a record of the various strategies they use to solve problems. I do allow students who understand the algorithm to use it, but I also challenge these students to try to solve the problem another way!This has worked really well in my grade 5 classroom. We are in our fourth year of Investigations.
