Thinking Blocks is a suite of learning tools designed to help students solve math word problems accurately and efficiently. Using brightly colored blocks, students model mathematical relationships and identify known and unknown quantities. The model provides students with a powerful image that organizes information and simplifies the problem solving process. By modeling increasingly complex word problems, students develop strong reasoning skills which will facilitate the transition from arithmetic to algebra.
I think placing a survey or poll on your classroom blog or website is a great way to get informal feedback from your students. I usually put a survey on my class blog a week or so before any formal assessment that my students are going to take. That feedback helps me identify the areas that my students need more help and or clarification on. - R M Byrne
