ProblemSum vs Singapore Math Drills

ProblemSum — unlimited PSLE problem sums, every one fully worked. PSLE word problems: ratio, fractions, percentage, money, algebra, rate, time, number patterns and more. Not geometry figures, charts or patterns drawn as shapes — those are read off a picture, and this app writes questions. Primary 6 maths practice that never runs out — because there is no question bank to run out of. No account. No subscription. No internet connection. Pay once and it is yours. NOT A QUESTION BANK Most practice apps ship a fixed set of questions. Work through them and you are done; work through them twice and your child is remembering answers instead of solving problems. ProblemSum has no such list. Every question is written when you ask for it, with its own names, numbers and quantities, and the working follows those numbers — so there is no end of the book to reach, and no set of answers to fall back on instead of the method. AND EVERY ONE IS WORKED THROUGH Type your answer, tap Check Answer, and the full solution opens underneath: the bar model drawn out, the units labelled, every line of working, and — on most questions — a check at the end proving the numbers really do add up. Most types also offer a second method, so a child who cannot see the model can follow the working through instead, or the other way round. BAR MODELS, DRAWN PROPERLY The model method is how Singapore classrooms teach these problems, so it is how ProblemSum explains them. Bars are drawn to scale with their units marked, the part that changed hands shaded, and braces showing what is left — drawn for the numbers in front of you. SOLUTIONS SET LIKE A TEXTBOOK Working is laid out the way it would be written on paper: fractions stacked over their denominators, ratios and percentages and money in their proper forms, and units carried through every line. BUILT FOR THE 2026 SYLLABUS Algebra is new to Primary 6, and it is here, with circles, three-term ratio, volume worked backwards, dividing by a fraction and percentage change. So is the earlier content the PSLE still examines: time and the 24-hour clock, factors and multiples, number patterns, area and perimeter, and discount, GST and interest. Rate comes as the charges a paper sets — by the hour, and in bands — and averages change as someone joins or leaves. WHAT IT COVERS, AND WHAT IT DOES NOT Ratio and fractions run deepest, then percentage and money, then volume and capacity, then algebra, average, rate, rate of work and whole numbers, with age, area and perimeter, circles, factors and multiples, mass, measurement, number patterns and time each drilled by their own kind of question. Every one is set at PSLE level. What it does not do: geometry from a figure, charts and graphs, and patterns drawn as shapes. Those are read off a diagram rather than a paragraph, so they sit outside what a word-problem generator can write. The Info tab lists both sides of that line, so you always know what you have. ANSWER IT THE WAY YOU THINK OF IT $4.50 or 4.50. Three-quarters as 3/4 or 0.75. A time as 1.45 p.m. or 1345. A ratio with spaces or without. ProblemSum accepts the formats a Primary 6 child actually writes, so a right answer is never marked wrong for its punctuation. COME BACK TO WHAT YOU HAVE DONE Recent questions stay on the device with their full solutions, ready to open and read through again. ONE APP, EVERY LEARNER Set up a profile for each child. Each one keeps its own score — questions attempted, questions right — so two children can share an iPad without sharing a total. IPHONE, IPAD AND MAC One purchase covers all three. On Mac and iPad with a keyboard, Command-N gives you the next question and Command-Return checks your answer. WORKS ANYWHERE, TELLS NO ONE ProblemSum makes no network connections at all. There is no account to create, no analytics, no advertising and no data collection of any kind — everything is generated on the device and stays there. Built for the Singapore syllabus.

Singapore Math Drills: Grades 1–6 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 1–6 (ages 6–12): structured, adaptive, stress-free practice that builds real number sense and problem-solving skill. WHY SINGAPORE MATH DRILLS? • Aligned to Singapore's MOE — every drill maps to the MOE mathematics syllabus for Grades 1–6: Whole Numbers, Fractions, Decimals, Ratio, Percentage, Geometry, and Algebra. • 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.
