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.
Levels 4 to 10 come with the family plan.
Roughly 5th through 7th grade, for kids who have their basic facts down. Level 1 is one-step equations and level 10 is multi-step word problems.
Equations like ___ + 7 = 15 or 3 x ___ + 4 = 19 are about undoing: work backwards with the opposite operation, last step first. Every answer can be checked by putting it back into the equation, which makes this a good place for kids to start checking their own work.
Order of operations (parentheses, exponents, multiplication and division, then addition and subtraction) matters as soon as an expression has more than one step: 7 + 9 x 5 is 52, not 80. Negative numbers and percentages round it out; in the Common Core standards most US schools follow, these come in 6th and 7th grade.
In a Kiwi Tutor account, each kid gets their own Pre-Algebra 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.
Pre-Algebra is part of the family plan ($10/mo): all 10 levels, adaptive for each kid, plus every other subject for up to 5 kids. Addition, Subtraction, Multiplication and Division stay free for up to 2 kids. Compare the plans ->
Is this pre-algebra practice free?
The practice box on this page is free, with no sign-up, for levels 1 to 3. In a Kiwi Tutor account, Pre-Algebra is part of the family plan ($10/mo), which unlocks all 10 levels with adaptive practice for each kid.
What grade is this pre-algebra practice for?
Roughly 5th through 7th grade, for kids who have their basic facts down. Level 1 is one-step equations 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 show the steps?
Yes. Every equation and order-of-operations question comes with a worked explanation built from its own numbers, for example undoing the + 8 first and then the x 9 in 9 x ___ + 8 = 71.
