Middle Ending Beginning Plot setting time place characters elements A B C D B-D-A-C Revision Put the following pictures into correct order. Read for information 1. How probably did the king feel at the end and why? He probably felt surprised. Because the king realized the problem— even with all the rice in the country, he would still not have enough rice to put on the chessboard! 2. What prize did the old man ask for? If he won the game, he'd like one grain of rice for the first square of the chessboard, two for the second, four for the third... He’d like the king to double the amount for each of the rest of the squares. Is that a HUGE amount? Let’s try to calculate! Dive into the calculation Square 1: 1 grain → Total = 1 Square 2: 2 grains → Total = 3 (1+2) Square 3: 4 grains → Total = 7 (3+4) Square 4: 8 grains → Total = 15 (7+8) 1 2 3 4 How many grains of rice would there be on the chessboard? double the amount 将数量翻倍 Dive into the calculation 1 2 3 4 Pair work: Calculate from Square 5 to 10 10 5 7 6 8 9 Square 5: 16 grains → Total = 31 Square 6: 32 grains → Total = 63 Square 7: 64 grains → Total = 127 Square 8: 128 grains → Total = 255 Square 9: 256 grains → Total = 511 Square 10: 512 grains → Total = 1023 Only 10 squares of grains of rice can reach up to 1023! How can we calculate the rest of the squares? Can you find out any rules？ =2^5-1 =2^6-1 =2^7-1 =2^8-1 =2^9-1 =2^10-1 So the total number of the grains of rice on the chessboard would be ________. Dive into the calculation 2^64-1 2^64-1=? Let’s ask DeepSeek for help. Can you imagine how large this number is? Let’s continue the talk with Deepseek!
