Maths worksheet: adding 9

Here are two maths worksheets of practice at adding 9 to a single digit. The obvious method to do this is to add ten and then take away one. However, this method is only efficient if ten is added mentally and not counted on. (Otherwise you might just as well count on 9!) Once again, the aim is for children to become quick and efficient in their heads so that answers are given just as quickly as if they were asked their name.
