I agree with this. As a software engineer, I have a strong interest in
processes, techniques, algorithms and patterns. I'll go further in saying that
a student can learn to develop his or her own algorithm or process in
experimenting with a calculator. But I'll also state that much of this can be
done without a calculator.

You stated that students could learn patterns/algebra using calculators given
specific operations to perform. This could be done without calculators (we did
this sort of thing when I went to school too). It could be done with the teach
asking for volunteers or with the students working in small groups with at
least on student strong in mental calculations in each group. For some, the
calculators have the advantage, and for others the group approach has the

Can fourth graders relate to rational numbers though?
