Method 1: Point method

14 remove nine sticks or dots, that is, one at a time, nine times, leaving five.

Method 2: Breaking Ten Methods

14 can be divided into 10 and 4, 4 minus 9 is not enough, minus 9 equals 1, and then 4 plus 1 equals 5. To sum up: first calculate 10-9= 1, and then calculate 4+ 1=5. Children must be made to understand the reason of+1=5 in Step 4 of Step 2, because 10 minus 5 equals 1, and 4 does not participate in the subtraction, so 4 and 1 should be combined.

Method 3: Ten-level method

14 minus 9 is 14 minus 9. We know that 14 can be divided into 10 and 4, so we can subtract 4 first, then 5 and 5, that is, calculate14 =10 first, and then calculate 18. The key to this method is to understand that 9 should be divided into 4 and 5, why 4 and 5, not 3 and 6, and so on. The reason is that we must first subtract a few from this dozen and turn this dozen into 10, which is more convenient for us to calculate. For example, 13-9, so that 9 divided by 3 equals 6, in short, the MINUS ten becomes 65438.

Method 4: Want to add and subtract.

We can think that 9 plus a few equals 14 and 9+6 equals 14, so 14-9 equals 6. In addition, this method requires students to be particularly skilled, from which they can feel that the connection between mathematical knowledge is particularly close.
