A growing library of mathcasts. Mathcasts are recorded movies created with a smart board with audio narration. Students can see and hear how a given problem is solved. Resources available for Grades 1-12.

Problem solving and Writing prompts for math for grades K-12.

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

Use the broken calculator to solve your math problems in a creative way. Can you add 2+2 if the addition key is broken? Sure can..how about (3*2)-2 . The answer is the same! Create some challenges for you, your friends, and teachers!

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.

Absurd Math is an interactive mathematical problem solving game series. The player proceeds on missions in a strange world where the ultimate power consists of mathematical skill and knowledge.

Challenging math problems for you to solve. Email your answer to find out if you are right!

Activities to explore and engage with mathematical ideas.
Provides challenging activities which provide students with opportunities to develop their mathematics.

After researching place value and numeration systems, students create a base-4 numeration system for a primitive alien tribe.

This web-based unit will introduce students to strategies and real-life practice activities for applying problem-solving skills. Students will investigate real problems through a variety of websites and group activities.

The students will measure the diameter and circumference of many circles and will estimate their relationship. By doing so, they should discover the approximate value of pi. By discovering it on their own they should feel rewarded and gain a deeper understanding of the fundamental concept of pi.

Try this...not as easy as it looks! What's your strategy??
