Twenty problems, sums reaching all the way to twenty. Addition facts practice 0-20 gives your student the full range of single and double-digit combinations they need to own before multiplication enters the picture.
Each of the 20 problems presents a horizontal addition equation with a blank answer line underneath. Sums range from simple single-digit pairs like 4+8 up to combinations like 10+10 and 2+16, covering the complete 0-20 range the title promises. This addition facts practice 0-20 worksheet is well matched to grades 1 and 2, where building automatic recall is the primary math goal.
Slot it into your math block as a warm-up, a timed drill, or an end-of-lesson check. Your homeschooler can work through it independently once they have been introduced to sums above ten. Repeated passes on this sheet reinforce the mental math habits that make multi-digit addition and early multiplication far less effortful later on.


A pencil with an eraser is the right call here so your student can self-correct without a messy page. The horizontal format asks for recall rather than stacking, which strengthens mental addition specifically. Independent practice works well once sums above ten have been introduced, though timed guided runs are useful for tracking fluency growth.

Standard 20 lb copy paper handles pencil writing fine for daily drill use. Portrait orientation is set, so print as-is. Running off several copies at once lets you use the same sheet for timed practice on multiple days.
