Get your child ready for Ontario's Grade 3 provincial assessment in eight calm minutes a day. Short daily practice in math, reading and writing, plus full practice tests with a score report that shows exactly which topics need work. Made for children aged 7 to 9, and clear enough for a parent to read at a glance. SEE EXACTLY WHERE THEY STAND Sit a full practice test: 19 questions across math, reading and writing on a 25-minute timer. There are no hints, and nothing is revealed until the end, the way a real test works. The score report then shows: • Their result by subject and by individual topic • The topics worth working on next, each with a simple tip you can use at home • How they have changed since their last test EIGHT MINUTES A DAY, THREE SUBJECTS • Math: number sense, operations, fractions, patterning, coding, geometry, measurement, data and money • Reading: stories, poems, procedures, biographies, news reports, notices and opinion pieces, with questions on understanding, inference, vocabulary and main idea • Writing: story, opinion and information prompts, with helper questions to get them started Nearly 1,300 questions and more than 100 reading passages in all. 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: math, reading or writing on its own • Custom Practice: choose the subjects and question count, timed or relaxed • Review Mistakes: revisits the questions they got wrong • Speed Round: a two-minute math blitz with high scores • Daily Challenge: one question a day to build a streak PRACTICE THAT FITS YOUR CHILD Questions adjust to your child's recent accuracy, so the work stays challenging without becoming discouraging. Every practice answer comes with a plain-language explanation, and your child moves on when they are ready. Nothing rushes them past an answer they are still reading. If timers cause stress, relaxed mode switches them off. ONE APP FOR THE WHOLE FAMILY Each child gets their own progress, streak, badges and practice tests, plus their own colour theme (Ocean, Forest, Sunset, Berry, Candy or Midnight), so the app feels like theirs and not their sibling's. Premium covers up to four children. MOTIVATION THAT LASTS • 32 badges to earn across nine categories • Daily streaks with a visual calendar • Celebrations when a badge is earned • Encouraging feedback at every score BUILT FOR PARENTS TOO • Topic-by-topic score reports • Accuracy trends and per-subject charts • Session history with an answer-by-answer review • A progress report you can share • Optional daily reminders PRIVATE AND OFFLINE Your child's name, answers, writing and progress stay on the device, and practice works without an internet connection. There is no account, no sign-in and no advertising. We count anonymous usage, such as how often a practice mode is used, on our own server, and share nothing with anyone. FREE TO TRY Start with five free practice sessions and a free practice test. The Daily Challenge and Speed Round are always free. Premium unlocks unlimited practice, unlimited practice tests and profiles for up to four children.
