Pick a level and answer real questions right here. Every question is made fresh, so there is always another one, and a wrong answer shows how to solve it step by step. These are the same questions Kiwi Tutor gives kids in their own practice.
Roughly 1st through 4th grade, but there is no grade picker: level 1 is facts within 10 and level 10 is multi-step word problems.
Subtraction facts grow out of addition facts: a kid who knows 8 + 5 = 13 also knows 13 - 5 = 8. Practicing them as fact families is faster than memorizing each one, and the Common Core standards most US schools follow expect fluency within 20 by the end of 2nd grade.
Borrowing (regrouping) trips up more kids than anything else in subtraction, especially across zeros, as in 400 - 158. Go one column at a time: when the top digit is too small, take 1 from the column to its left, which adds 10 to this one. Checking the answer by adding it back is a habit worth building.
In a Kiwi Tutor account, each kid gets their own Subtraction level, set by a short placement quiz. A few right answers in a row and the next questions get a little harder; a couple of misses and they ease back. Wrong answers come with the same step-by-step explanation you see here, missed topics come back until they stick, and a parent can see each kid's accuracy by topic.

What grade is this subtraction practice for?
Roughly 1st through 4th grade, but there is no grade picker: level 1 is facts within 10 and level 10 is multi-step word problems. In a Kiwi Tutor account, a short placement quiz finds where each kid should start.
Does it practice subtracting across zeros?
