Carrying & borrowing
Japanese school year: Elementary 1
What you learn
Using groups of ten, learners practice addition with carrying and subtracting a single digit from teens with borrowing. This concept deepens understanding of place value and prepares students for larger calculations. A solid grasp of calculations within 10 makes this topic easier to master.
Key points
In addition with carrying, break apart one number to make a group of 10 first.
In subtraction with borrowing, subtract from a group of 10 first, then add the rest.
Remember to add the carried 1, and do not forget to take away 1 after borrowing.
