There are many ways to cultivate students' interest in learning. Pupils love to play, and creating appropriate hands-on activities can make learning easy and efficient. When teaching Understanding of Abacus this semester, I used both the big abacus, the teaching aid of the school, and the small abacus I found myself. The number of beads on the two abacus is different, but students can clearly indicate that each bead represents 5. Through objects, students can remember the names of the parts of the abacus more deeply.
Second, the use of teaching AIDS can help students form a sense of numbers.
Children's cognitive law is "perception-representation-concept", and the operation of teaching AIDS just conforms to this law, which can make students become beautiful and active, and fully mobilize students' various senses to participate in teaching activities. When I was teaching the second volume of second-grade mathematics, I felt that the number within 1000 was relatively small. Students already knew the number within 100, so they didn't use the counter. When counting, some students don't know what's behind when they meet 199, and the numbers behind the whole hundred are also very inaccurate. Therefore, when learning the number within 10,000, I used a counter. With the aid of teaching AIDS, students can intuitively see the changes after adding a number, so the teaching effect of this lesson is better than the understanding of numbers within 1000.
Third, the use of teaching AIDS can cultivate students' ability to solve problems and innovate.
Proper use of teaching AIDS in class can help students to use appropriate tools when solving problems, make students naturally think of hands-on operation to solve problems, and cultivate students' hands-on ability and brain thinking ability.
In a word, I think the use of teaching AIDS can effectively improve the teaching effect of mathematics classroom. Teaching AIDS and learning tools should be used properly in the early and late teaching to stimulate students' interest in learning and cultivate their learning ability.
