CrazyMinute vs Singapore Math Drills

Created by a parent and a primary-school teacher, CrazyMinute is a fun math quiz on basic facts with a myriad of problem variations and a unique interface. iPad users also have an additional game variation to choose from: see the companion app MathNight, exclusively for iPad. This 60-second quiz incorporates playful sound effects along with the unique digitBar™ interface for easily entering answers. With one finger or thumb dedicated to the ones place and one for the tens place, students can quickly enter and correct answers while reinforcing an important understanding of how numbers are built. Created for everyone, there is no text used anywhere in the game: all interaction is stripped-down to the essential meanings of numbers, math symbols, and a few colored buttons, making it perfect for early readers and parents worldwide. Each game reviews skills in addition, subtraction, multiplication or division; players can choose quizzes from a range of random values (from 0 through an upper-bound) or against a fixed value (to focus on just “your 8s” for example). Designed for positive reinforcement, problems simply remain on the screen until answered correctly, so there is no penalty other than lost time for typos or incorrect attempts. Whatever skill level you work on, practicing basic math facts helps all math students create a solid foundation for working easily with all types of mathematics, and will help students progress quickly through the “Mad Minute” quizzes given daily in many schools’ early grades. How many can you answer, before time runs out?

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 — 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? • Singapore MOE-aligned practice spans Grades 1–10, with selected G3 topics in Secondary 2–4. G3 Mathematics — Additional Mathematics is not covered yet. • Bar Models, Explained Simply — 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. • Concrete-Pictorial-Abstract Teaching — every new skill starts with real objects, then a picture, then the abstract number sentence, so the "why" sticks. • Adaptive Learning — difficulty tunes itself to your child's recent sessions, and daily suggestions point straight at what needs work. • Calm Gamification — 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 • Daily Drills & a Daily Five — short sessions of mental math, practice problems, and word problems, with five hand-picked drills waiting each day. • Three Practice Modes — Focus (untimed mastery), Sprint (rapid recall), and Worksheet (a full test-style set graded at the end). • Progressive Hints & Worked Solutions — every question opens up step by step, with a full worked solution to read afterwards. • Skill Map — a visual mastery breakdown across every topic, down to the exact subtopic. • Prerequisite-Aware Support — when a child gets stuck, the app folds in the missing foundation skill instead of repeating the same question type. • Build-a-Drill — pick the topics and question types and build a custom practice set. • Optional Placement Check — an adaptive quiz that suggests a starting level, available on request, never forced. • A Companion That Grows With Them — species and stage earned through consistent practice, with encouraging, never-nagging dialogue. • A Growing Collection & Daily Quests — streak and quest drops build a collection over the school year, with a daily "Up Next" queue keeping momentum. • Stars, Streaks & Levels — calm progression that rewards showing up and getting things right, never speed. FOR PARENTS • Weekly Digest — one clear weekly summary of what your child mastered and where they need focus. • Progress Reports — a verdict in plain words, not a wall of numbers, with full attempt history available to review. • Focus Areas — struggling topics surface automatically, with the foundational skill to tackle first. • Family Accounts — one parent account manages each child's independent, self-referential progress — 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.
