The bar-model method, taught the way a teacher draws it
Bar Model Studio teaches the Singapore model method one grade at a time: an instructor draws each bar, bracket and question mark step by step, then your child builds the same model with their own hands — placing every number where the story says it lives. Every problem is generated fresh and checked against Numi’s own answer engine.
A ladder from P3 to P6
Ten lessons climb the syllabus: whole-number comparison and two-step chains at Primary 3, fraction of a set at Primary 4, fraction chains and rate at Primary 5, ratio and percentage at Primary 6 — each bound to its MOE topic.
Watch one, then build one
Each lesson first performs the model — bars drawn, labels flying from the story sentence to their place — then flips: the child constructs the model and is coached on structure, never given the answer.

Frequently asked questions
What is the bar model method?
The bar model (Singapore model method) turns a word problem into bars whose lengths show the quantities and their relationships, so the operation can be read off the picture before any arithmetic. It is central to how MOE primary mathematics is taught.
Which levels do the lessons cover?
Primary 3 to Primary 6, one topic ladder: comparison and two-step problems at P3, fractions at P4, fraction chains and rate at P5, ratio and percentage at P6.
Is there a free bar model lesson?
Yes — the Primary 3 comparison lesson is free with no sign-up and no data stored. The remaining lessons unlock with a free account.
