Try a real bar-model lesson — free, no sign-up
This is the Primary 3 comparison lesson from Numi’s Bar Model Studio, open to everyone: an instructor draws each bar, bracket and question mark step by step, then your child builds the same model with their own hands. It stores nothing and needs no account.
What your child learns
The comparison model — the bar drawing that turns “Ali has 12 more than Ben” word problems into two bars whose difference you can SEE, so the operation reads straight off the picture. It is the backbone of MOE Primary 3 problem solving.
Watch one, then build one
The lesson first performs the model: bars drawn by a moving pen, numbers flying from the story sentence into their places. Then it flips — your child constructs the model themselves and is coached on the structure, never just told the answer.
Genuinely free, genuinely private
No account, no email, no data stored — the lesson runs entirely in the browser and forgets everything when you leave. The rest of the P2–P6 bar-model ladder opens with a free account.
