1, initially let children know the meaning of more, less and as much, know the greater than sign, less than sign and equal sign, and their usage and significance.
2. It can be used as a short story to introduce how to know that the number is greater than the number. For example, Lin Mei is going to hold a sports meeting. There are four little rabbits and three little monkeys. Then there are more rabbits than monkeys, and then there are more rabbits than monkeys.
3. On the contrary, there are not as many three little monkeys as four little rabbits in the same story, and the number of the same little monkey is less than that of the little rabbits, which can guide the meaning and application of children.
Equal to it, you can use the same story as a guide. There are already four little rabbits and three little monkeys, and now there are four little frogs on the playground. Let the number of little frogs be the same as the number of little rabbits, which can guide children to equate the number of four little rabbits and four little frogs and let them understand the meaning of equality.
The call story of greater than sign and less than sign equals sign
A long time ago, the kingdom of mathematics was chaotic. 0 190 brothers not only dominate the kingdom, but also brag about their best skills. The math angel was very angry when he saw this situation and sent someone.
Three little angels came to the kingdom of mathematics, and ten brothers looked at them contemptuously. Q: "What are you three doing in the kingdom of mathematics? You are not welcome! "
He smiled and said, "We are judges sent by angels to help you govern your country. I am an equal sign, and these two are' greater than sign' and' less than sign', and whoever they open their mouths to is the biggest; Whoever they point to is small. "
The 0-9 brothers heard that they were judges sent by angels, so they obeyed? 、? And =。 Since then, the mathematical kingdom has a strict order, and no one will violate it.
