Jon Dreyer: Student Work

Here is some annotated work of my students.

I try to help students to be able to use practical techniques but also to maintain a deep understanding of them. This student shows that she knows a quick way to convert a decimal to a percent and also that she understands the mathematics behind this technique.

I move the decimal point two places to the right. (In other words, I multiply by 100)

I try to help students to see the interconnectedness of math. Here the same student shows that she knows that a percent is just shorthand for a particular kind of fraction.

A percent is just a fraction with a denominator of 100.

Some students get the concept but still need work on technique. I plan to do more work on basic skills. Ideally, deep comprehension promotes basic skills and vice versa, but in practice we need to spend time on each.

(Right idea but faulty execution)
