I created math addition practice packets for 1-digit, 2-digit, 3-digit, and 4-digit addition practice and am selling them on Teachers Pay Teachers. You can buy the whole bundle, or buy each level individually (links below).
These packets offer graduated addition practice starting with adding 0 to 1-digit numbers, all the way up to adding 4-digit numbers to 4-digit numbers. They gradually introduce carrying and place value. All together there are 180 practice sheets (30 problems per sheet), great for home schooling parents or teachers wanting to offer practice at levels that are just right for each child.

If you want to make more, or customize these pages further for your kids, you can do that directly using the math activity on The Trip Clip® website.
Each practice sheet is a half sheet of paper, which fits great on the kid-sized clipboard from The Trip Clip®:
