Most math apps ask you to pick a grade and hope it fits. Kiwi Tutor skips that guess: a short placement quiz finds a starting level in each operation, then every single answer nudges that level up or down - a few right in a row and it gets a bit harder, a couple of misses and it eases back. No grade picker, no plateaus, no review that's too easy to hold a kid's attention.
Addition, Subtraction, Multiplication, and Division start at simple facts and build up through carrying, borrowing, and multi-step word problems. Fractions and Decimals get their own 10-level curve built for how they're actually taught - adding fractions with unlike denominators, simplifying to lowest terms, decimal word problems. Pre-Algebra is the newest addition: one- and two-step equations, order of operations, exponents, negative numbers, and percentages - real algebra readiness, not just harder arithmetic.
Get a question wrong and Kiwi Tutor doesn't just show the right answer - it shows the actual reasoning, built from the exact numbers in that question. A two-step equation like 9 × ___ + 8 = 71 walks through undoing the +8 first (71 − 8 = 63), then the ×9 (63 ÷ 9 = 7). An order-of-operations question like 7 + 9 × 5 explains why multiplication happens first (9 × 5 = 45), then the addition (7 + 45 = 52). It's generated fresh from that specific question every time, not a canned tip.

What age or grade is Kiwi Tutor's math practice for?
There's no fixed grade - each kid gets their own adaptive level per operation from a placement quiz and ongoing performance, so it naturally covers elementary math from early addition facts through pre-algebra.
Is Kiwi Tutor's math practice free?
Yes - Addition, Subtraction, Multiplication, and Division are free with unlimited adaptive practice for up to 2 kids. Upgrading ($10/mo) unlocks Fractions, Decimals, and Pre-Algebra, plus every other subject.
Does Kiwi Tutor teach pre-algebra?
Yes - Pre-Algebra is one of the seven math operations, covering one- and two-step equations, order of operations, exponents, negative numbers, and percentages, each with its own adaptive difficulty level.
Does my kid need to already know their math facts to start?
No - a short placement quiz finds a starting point in each operation automatically, and every answer adjusts the difficulty from there, so a kid who's behind or ahead both land somewhere that actually fits.
