The ten-point method of children's mathematics has the following topics. For parents' reference:
Review the addition of 10 first, so as to lay a foundation for feeling the superiority of the method of adding ten.
For example, there is a clever little monkey who wants to test everyone (the courseware shows the little monkey). Do you have confidence?
10+ 1=( ) 10+7=( ) 10+3=( ) 10+8=( )
10+5=( ) 10+6=( ) 10+2=( ) 10+4=( ) 10+9=( )
Look at the box and count. Let the children build the box into a model of 10 in their minds.
Example: Say to the children: The little monkey wants to give you a present. (Showing an empty box) This box is amazing and can help us solve math problems. Do you want to know its secret?
1. Let's take a closer look: How many squares are there in a * * *?
2. If each cell contains a pineapple, how many can a * * * hold?
Show five pictures of pineapples: How many pineapples are there now? How did you know?
4. Show five or six pineapple pictures, ask the same questions as above, and feel the models of 3 plus 7 and 8 plus 2.
5. Show the picture of 10 pineapple. Summary after the question and answer: when it is full, it is 10.
Third, you can do some small animal tricks:
Little turtle's apple, 9+5. Continue to feel the superiority of rounding off ten.
3, rabbit's radish, 8+5. Continue to feel the superiority of rounding off ten. Feel the key to rounding ten: according to the different objects of rounding ten, divide the corresponding numbers and make ten.
One more question: How did this 10 get together?
4. Peacock strawberry, 7+5. Continue to feel the superiority of rounding off ten. Feel the key to rounding ten.
The method of supplementing ten in children's mathematics is a simple and quick calculation method, which is very helpful for children's mathematics learning.
