Singapore Math Drills: Grades 1–10 Practice Built on the Singapore Method Singapore consistently ranks among the top performers in international math assessments like TIMSS and PISA, using a syllabus built on understanding a problem before solving it β€” not memorizing steps. This app brings that method to Grades 1–10 (ages 6 through 16): structured, adaptive, stress-free practice that builds number sense and problem-solving skill. WHY SINGAPORE MATH DRILLS? β€’ Singapore MOE-aligned practice spans Grades 1–10, with selected G3 topics in Secondary 2–4. G3 Mathematics β€” Additional Mathematics is not covered yet. β€’ Bar Models, Explained Simply β€” a simple picture that turns a tricky word problem into a diagram, so a child sees the relationship between numbers instead of guessing an operation. Singapore Math's signature tool, built into every relevant drill and the app's own scratch pad. β€’ Concrete-Pictorial-Abstract Teaching β€” every new skill starts with real objects, then a picture, then the abstract number sentence, so the "why" sticks. β€’ Adaptive Learning β€” difficulty tunes itself to your child's recent sessions, and daily suggestions point straight at what needs work. β€’ Calm Gamification β€” no stressful timers, high-pressure games, or dark patterns. We reward accuracy and honest progress, measured only against a child's own past results. FOR STUDENTS β€’ Daily Drills & a Daily Five β€” short sessions of mental math, practice problems, and word problems, with five hand-picked drills waiting each day. β€’ Three Practice Modes β€” Focus (untimed mastery), Sprint (rapid recall), and Worksheet (a full test-style set graded at the end). β€’ Progressive Hints & Worked Solutions β€” every question opens up step by step, with a full worked solution to read afterwards. β€’ Skill Map β€” a visual mastery breakdown across every topic, down to the exact subtopic. β€’ Prerequisite-Aware Support β€” when a child gets stuck, the app folds in the missing foundation skill instead of repeating the same question type. β€’ Build-a-Drill β€” pick the topics and question types and build a custom practice set. β€’ Optional Placement Check β€” an adaptive quiz that suggests a starting level, available on request, never forced. β€’ A Companion That Grows With Them β€” species and stage earned through consistent practice, with encouraging, never-nagging dialogue. β€’ A Growing Collection & Daily Quests β€” streak and quest drops build a collection over the school year, with a daily "Up Next" queue keeping momentum. β€’ Stars, Streaks & Levels β€” calm progression that rewards showing up and getting things right, never speed. FOR PARENTS β€’ Weekly Digest β€” one clear weekly summary of what your child mastered and where they need focus. β€’ Progress Reports β€” a verdict in plain words, not a wall of numbers, with full attempt history available to review. β€’ Focus Areas β€” struggling topics surface automatically, with the foundational skill to tackle first. β€’ Family Accounts β€” one parent account manages each child's independent, self-referential progress β€” no comparisons between siblings or classmates. Ad-free. No tracking. Nothing asked of a child but honest practice. SUBSCRIPTIONS Free to start, with optional subscriptions unlocking the full curriculum and deeper parent reporting.
