Why parents choose Math-U-See

  • Mastery first: one topic until it’s solid
  • Blocks make every idea something you can see
  • A short video for every lesson
  • Build it, write it, say it, teach it back

How we teach Math-U-See

Same lessons, same order, same blocks. Here’s Algebra 1, Lesson 27: factoring trinomials.

Math-U-See Algebra 1 · Lesson 27 · Factoring trinomialsTrial lesson
  1. x² + 5x + 6
  2. 2 × 3 = 6, 2 + 3 = 5the units fill the corner
  3. (x + 2)(x + 3)the sides of the rectangle

SenseiLet’s build x² + 5x + 6 with blocks and try to make a rectangle.

Study notes for every lesson

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

Algebra 1Lesson 27 · Factoring

The new idea

Build the trinomial with blocks. If it makes a rectangle, the sides are the factors.

Worked example

  1. x² + 5x + 6
  2. find two numbers: × 6, + 5
  3. 2 and 3
  4. (x + 2)(x + 3)

Watch out for

  • Numbers that multiply but don’t add
  • Dropping the signs
  • Not checking by multiplying back

Where Math-U-See gets hard, and what we changed

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

What parents struggle withWith HeySensei
ForgettingMastery first means a topic can fade once your kid moves on.We bring back what’s fading in every practice set, so it stays solid.
The challengeQuick kids find it too easy, and the word problems light.Practice rebuilt every day from what your kid missed. Harder and faster once it’s solid.
The upper levelsPast Algebra 1 the blocks fade out, and the video can’t answer a question.Sensei teaches every lesson and answers when your kid asks.
Teaching it backTeaching back needs a parent who’s there and knows the math.Your kid explains it back to Sensei, out loud.
The gradingYou check every lesson 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.

“Once the blocks dropped away in Algebra 1, I was lost. Now he has someone who can answer his questions.”

Math-U-See questions

Do I still need the book?

No. Keep it if you like it.

Do we need the blocks?

No. Sensei draws them on the whiteboard. Keep yours if your kid likes building along.

Are the tests still there?

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

My kid is ahead of (or behind) the book. What happens?

Start at the lesson they’re on. If they already know it, they move ahead. If something from earlier is missing, we go back and fill it in first.
