Math Matters Level 5 - Chapter 1- Lesson 2
KING'S CHESS REWARD
Legend has it, that a long time
ago a Chinese king had a faithful and clever servant who invented
the game of chess. The king asked him what he would like as
his reward for this wonderful game. The servant said that he
wanted a grain of rice on the first square and two on the second
square and so forth doubling the grains of rice on each square.
For this example we are using the number of grains of rice through
27 squares on the chessboard which would total 67,108,864 grains
of rice.
It would take 3 large bags of
rice to equal the amount of rice from the first 27 squares of
the chessboard.
Write 67,108,864 three different
ways then put them in a place value chart.
Type the number 12,345,678 in the place
value chart below.
