Grade 3 is the year most Ontario students sit their first province-wide assessment. Grade 3 Test Trainer turns getting ready into a calm eight-minute daily habit — no cramming, no pressure, just steady practice in the three areas that count. Designed for children aged 7 to 9, with progress a parent can read at a glance. Know exactly where they stand Sit a full practice test: 19 questions across math, reading and writing, under a 25-minute timer, with no hints and nothing revealed until the end — the way the real thing works. The score report then breaks the result down by subject and by individual topic, names the two or three areas worth working on next, and compares the whole thing to their last test so you can see which way they are heading. A full session in eight minutes • Math — number sense, patterning, geometry and measurement • Reading — passages with comprehension and inference questions • Writing — narrative, opinion and informational prompts Seven ways to practise • Practice Test — a full timed test, then a detailed score report • Full Practice — a balanced session across all three subjects • Subject Practice — focus on math, reading or writing on its own • Custom Practice — pick the subjects, question count, and timed or relaxed mode • Review Mistakes — automatically revisits the questions they got wrong • Speed Round — a two-minute math blitz with high scores • Daily Challenge — one question a day to build the streak 197 questions and 21 reading passages, covering stories, poems, procedures, biography and news reports. Practice that adapts Questions are chosen to match your child's current accuracy, so the work stays challenging without becoming discouraging. Every question in ordinary practice comes with a plain-language explanation, and your child decides when to move on — nothing rushes them past an answer they are still reading. A profile for every child Each child gets their own progress, streak, badges and practice tests — and their own colour theme, from Ocean to Forest to Candy, so the app looks like theirs and not their sibling's. Premium covers up to four children. Motivation that lasts • 29 achievement badges across eight categories • Practice streaks with a visual calendar • Celebrations when a badge is earned • Encouraging feedback at every score level Made for parents too • Score reports with a topic-by-topic breakdown • Accuracy trends and per-subject charts • Session history with an answer-by-answer review • A progress report you can share • Optional daily practice reminders Private by design Everything stays on your child's device. No account, no sign-in, no analytics, no advertising, and nothing shared with anyone. Free to try Five full practice sessions are free, and the Daily Challenge and Speed Round are always free. Premium unlocks unlimited practice, full practice tests, and profiles for up to four children. Premium options • Monthly — $3.99 per month, after a seven-day free trial • Yearly — $29.99 per year, after a seven-day free trial • Lifetime — $49.99, a single payment, not a subscription Payment is charged to your Apple ID at confirmation of purchase.
