Description
"Adding three digits with two or three digits using discontinuous carry" Addition and subtraction of two or three digits PPT courseware
The students made a batch of leaf stickers and selected 142 for display in the window, with 86 left. How many paintings were produced in total?
Add two or three digits to a three-digit number, align the same digits, then add the numbers in the same digits, and write the result in the corresponding digits. Whichever one adds up to ten, advance 1 to the previous one.
The method of checking addition is to swap the positions of the two addends and then add them again. If the two results are equal, it means the result is correct. If they are not equal, it means the result is incorrect and needs to be recalculated.
Teaching postscript:
This is a comprehensive teaching content, and students are highly motivated. The key is to cultivate the students' habit of writing vertically correctly. I used methods such as asking students to come on stage to review, compare, and evaluate each other, and the results were good!
