In this post you will find ten worksheets on basic horizontal addition. In grade 2, kids need an opportunity to develop some mental math abilities and I think giving them one digit addition worksheets is a good one.
These worksheets start with simply adding 1 to another one or two digit number and then go on to adding three and four one digit numbers.
I know there are 10 worksheets but once kids start on the first one they keep asking for more. Give them a try to make your toddlers smart in math.
