# Pythagoras Theorem Game

*Material Required: Chart paper for making the board and question cards, cutter, buttons, a pair of dice.*

This game is meant to familiarize students with the Pythagoras theorem which plays a crucial role in school geometry.

In this game two or more students roll a pair of dice to move around the triangular board shown in the figure. Copy out the board on to chart paper. Make question cards by copying each question on to a separate card. Both the dice have to be rolled together. Add the squares of the numbers on both the dice and take the square root (from the famous theorem a2 + b2 = c2 ). Round off the answer to the nearest whole number and move that many spaces.

For example, if you have rolled 1 and 2 on the dice, then c2 = 12 +22 = 5. Since <math>\sqrt{5}</math> = 2.236 approx., you move 2 spaces.

Follow the instructions given on the square you come to. If your square is marked with a ‘?’, you have to pick a card at random and answer the question on it. If you answer correctly you get a chance to roll a single dice and move the number of spaces it shows. A wrong answer means you stay on the square till your next turn. The first player who goes twice around the board wins.
