Activity process
1, showing the comparison of math cards.
Teacher: Elephants and ants are good friends in the forest. Although different in size, they help each other. The elephant is very big. Little ants are sitting on the elephant's back and playing happily.
(1) Look, children, what's the difference between the body of a small ant and that of an elephant?

Show these pictures:
(1) What kind of graph is this? Which home should I go back to?
(The child said that the teacher operates big pictures, and I will send you to the big standard house;
I'll take you to Marco's house. )
