## Primo: A Mathematics Board Game About Prime Numbers

One of the latest cool math games I have come to know recently is Primo, a mathematics board game that looks very promising. It can be played by 2-4 players from age 10 and and above.  I have never actually played it yet, in fact it is still in its testing phase, but it really looks very interesting.

How to Play Primo

Primo is a race towards the center of the board. Each player has two pawns (yes, chess pawns), and alternately rolls two 10-sided dice.   The four fundamental operations (addition, subtraction, multiplication, and division) can be applied to the numbers obtained from the roll to determine the movements of the pawns. The player who lands two pawns at 101 or the center of the board wins the game. » Read more

Flashmaths is a web resource for elementary and middle school students who want to do math activities and play games. The site contains some good Flash-based interactive activities and games with varying difficulties. These activities and games may help improve students’ mathematical skills.

One activity I like in particular is the Angle Estimator activity where users can move the slider to estimate the angle shown.  The average error is then calculated. The user with the smallest Average Error is the best estimator.

## The Codebreaker Game

Codebreaker is an online logic game that allows the player to guess  a correct color combination “code.” In each guess (represented by the rows of circles in the leftmost part of the diagram), the computer places  black circles in  smaller pegs (see circles below the Accept button in the diagram) to indicate the number of colors in the right position, and white circles to indicate the number of correct colors in the wrong position. The player is allowed up to eight guesses to win the game, otherwise he loses.

The Codebreaker Game is very similar to Mastermind, a well-known board invented by Mordecai Meirowitz. It’s a good game for developing critical thinking of students. A good activity would be to let students develop their own strategy of making the least number of guesses in breaking the code.
