# Courseware # Introduction Traditional teaching methods are boring, and there is no intuitive form for students to understand. With courseware teaching, rigidity becomes vivid, abstraction becomes vivid, abstruse becomes simple and boring becomes pleasant. It can not only stimulate students' interest in learning, but also help them understand its meaning. The following is the courseware "less than, equal to, greater than" collected for you in the first grade of primary school mathematics. I hope I can help you. If you feel good, you can share it with more friends!

The first volume of primary school mathematics "less than, equal to and greater than" courseware 1

Teaching objectives:

1. Initially learn to compare the number of objects by one-to-one correspondence, and understand the meanings of "same quantity", "more" and "less". Knowing the meaning and usage of =, > will compare the sizes of numbers within 5.

2. Cultivate initial observation ability, thinking ability and language expression ability.

Teaching focus:

=, >, and are used to represent the relationship between two numbers.

Teaching process:

First, introduce new lessons.

We have learned the understanding of 0 ~ 5 before, and today we know that "=" and ">",, and, and, 3 points to the greater than sign, which is called the greater than sign.

(On the blackboard: greater than the number) Let the students say greater than the number, and then say the name.

In which direction does the opening of the size greater than open? Pointy (to the left)-which way is the head?

(5) Observe Equation 5 >; 3. Q: Which is bigger, the open end or the tip? Which is smaller? Is the big mouth facing a large number or a decimal number? What number does the tip point to? This formula is read as "5 is greater than 3" and written on the blackboard; 5 is greater than 3.

The teacher led the reading, read together, and talked with each other at the same table.

(6) Looking back, I just learned "greater than number". Who is this question? Who is it? What was the result? The teacher concluded: This question is the ratio of little squirrel to little bear. There are more squirrels than bears, 5 to 3. It can be said that 5 is greater than 3 and written as 5>3.

3. I can't teach.

(1) What's the comparison between a bear and a squirrel? There are fewer bears than squirrels. There are three bears and five squirrels. Little bears are less than squirrels, that is, 3 to 5, 3 to 5 to 5.
