One, one, two, two, two, four, one, three, three, six, three, nine, one, four, two, four, five, five, five, five, ten, five, five, six, six.
Eight out of eighteen, 286, 384, 483, 584, 688, 786, nine out of ten, 298, 327, 496, 594, 654, 793 and 897.
The characteristics of the multiplication table are: from "one to one" to "998 1", but in ancient times it was the other way around, from "998 1" to "1249 12 to 4". Because it is decided that the C word is "99", people call it "99". 13 and 14 centuries ago, just like now, "one by one got 1998 1 1".
Let students go through the compilation process of multiplication formula of 8, and be able to compile and memorize multiplication formula of 8 independently. Let students experience the joy of success in the process of cooperation with their peers and enhance their confidence in mathematics learning.
