Columbus State University’s College of Education is now the home of the Problem of the Week math contest, which was started in 1996 by David Rock and Doug Brumbaugh. The math educators also supply problems and answers that are part of the current White House Math Challenge, a presidential effort to boost interest in math and foster problem-solving skills. Visit our history page for more on these and the companion problem-solving sites here — Algebra in Action, Middle School Madness and Elementary Brain Teaser.

This interactive program teaches children how to visualize and solve math word problems. Using virtual blocks and cubes, children create models that illustrate the underlying math concepts in word problems.
Each Thinking Blocks program contains six guided practice sets and three assessment tests. The addition and subtraction program features models that represent part-whole, comparison, and change situations. The multiplication and division program introduces equal parts, comparisons, and interpreting remainders.
Program features include:
• Self paced, guided instruction that shows students how to correctly model math word problems
• Independent practice sets that challenge students to apply what they’ve learned
• Interactive blocks that engage students in the problem solving process
• Randomized problem sets that create a different learning experience each time the program is accessed
• Video tutorials which help students transition from building concrete models to sketching models on paper
• Printable certificates that allow students to keep a record of the work they have completed

Mathcasts can Help students learn & review math.
Help teachers collaborate & improve their teaching.
Help parents help their children and enable them to see examples of their childrens' work. Mathcasts.org was created to give students a library of math tutorials and problem solutions and to give teachers a place to share their methods for teaching & learn from others. It's also a place where students & teachers can contribute and organize sets of movies for others or themselves to use.

The rules of the game are simple: each of the nine blocks has to contain all the numbers 1-9 within its squares. Each number can only appear once in a row, column or box. Every puzzle has just one correct solution.
