How we teach Singapore Math

Same chapters, same order, same bar models. Here’s Dimensions Math 7A, Chapter 4: ratios with bar models.

Dimensions Math 7A · Chapter 4 · Ratios with bar modelsTrial lesson
  1. 3 : 5 → 8 units
  2. 8 units = $48
  3. 1 unit = $6so Ali gets 3 × $6, Ben gets 5 × $6

SenseiAli and Ben share $48 in the ratio 3 : 5. Let’s draw it before we calculate anything.

Study notes for every lesson

Each lesson comes with one page of notes in the order of the book: the new idea, a worked bar model, and the mistakes to watch for. Your kid can look back at them any time.

Dimensions Math 7AChapter 4 · Ratios

The new idea

A ratio compares equal-sized parts. Draw one box per part, then find what one box is worth.

Worked example

  1. 3 : 5 → 8 units
  2. 8 units = $48
  3. 1 unit = $6
  4. Ali: 3 × 6 = $18

Watch out for

  • Boxes of different sizes
  • Dividing by 3 or 5 instead of 8
  • Forgetting the units ($)

Where Singapore Math gets hard, and what we changed

What parents struggle with most, and what we did about it.

What parents struggle withWith HeySensei
The teachingThe books expect a parent to teach, often with methods you never learned yourself.Sensei teaches every lesson, bar models included. You don’t need to learn the method first.
Word problemsKids get stuck halfway through a multi-step problem, and the answer key only shows the answer.A hint on the exact step they’re stuck on, drawn as a bar model. Never the answer.
The jumpDimensions 7 and 8 move fast and get abstract quickly.Practice rebuilt every day from what your kid missed. Slower when it’s new, harder once it’s solid.
After grade 8Dimensions ends at 8B, so you have to switch programs for high school.We carry on through Algebra 2 and Calculus with the same teacher.
The gradingYou check every workbook page and every test.Every line graded from a photo of their paper, tests too. You see which skills are solid, which slipped, and a predicted grade for the year.

“Bar models finally clicked, for both of us. He draws them on his own now, even when nobody asks.”

Singapore Math questions

Do I still need the books?

No. Keep them if you like them.

Are the tests still there?

Yes. Same chapter tests. We grade them and show you what they mean.

We use Primary Mathematics, not Dimensions. Does that work?

Yes. Both are mapped. Tell us the book and the chapter.

What happens after 8B?

Your kid moves straight on to Algebra 1 with the same teacher, no new program to buy.
