Written Multiplication & Division

Write and calculate mathematical statements for multiplication and division using known tables, including two-digit × one-digit, using mental and progressing to formal written methods

Lesson

Set out your lesson

Connect partitioning with a compact written multiplication method.

Before teaching

Use this short check, then start teaching.

Activity

Inferred, not a taxonomy edge: learner can access the supplied prompt with agreed support and can explain or mark a response. If earlier skills are unfamiliar, use the prerequisite topic for teaching; an authored prerequisite is not proof this learner is ready.

Printer, credit, and teaching notes
Sequence

  • Keep the two adult-only cards off the learner screen. Have a pencil and scrap paper if useful; oral pointing/typing/AAC can replace handwriting unless spelling or composition is the target. No printing, cutting, account or purchase is required.

  • Open Show first, read the explanation together, and pause to check the central idea. Then do Guided Try together.

  • For Try, close earlier models and the adult keys unless the task explicitly supplies a reference. Record any hints, read-aloud help or model reopening; do not call supported work independent.

  • Use only the active learner card. Keep the private key closed until an attempt is recorded. Stop or take a break on request; practical claims stay not observed unless actually done.

No Printer

Use on screen; read aloud or recreate a tactile model only with declared support. No printer or purchased kit.

Privacy

Never display adult keys or dictation spellings with a learner task; no family financial, identity or conflict disclosure.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view.

Teaching limits and safe use

These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.

  • Finite whole-number examples, not all short division algorithms or automatic fluency.

  • These bounded examples do not establish independent performance in other situations. Record the support used.

Never display adult keys or dictation spellings with a learner task; no family financial, identity or conflict disclosure.

How Many Colored Pencils?

Open practice (new tab)
Before you open · source notes

A pencils story supports written multiplication and related division thinking. Not every fraction quotient.

Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.

Before you open

Ask the learner to show a written multiplication for the pencils and say a related division.

Opening this link does not save learning or assess mastery.

Source, access and review notes

Public Illustrative Mathematics task page. The .html address responds HTTP 308 to this URL. An anonymous GET of this URL on 2026-11-12 returned HTTP 200 with no login or payment prompt. Where a teacher solution is present, it is on the same page as the student task; this check did not find a separate locked student view. An adult can use the student view section and should not read a solution aloud. Advertising was not observed in the fetched HTML text; that is not a browser, device, or ad-free guarantee. This is a paper or discussion task, not an automatically marked interactive game. Opening the link does not save practice or assess mastery. Diagrams on the page use missing or filename-only alt text, so they are not an accessible image equivalent. Accessibility still depends on an adult describing the picture.

Check understanding

  • Calculate 23 × 4 using partitioning (20 × 4 + 3 × 4)
  • Calculate 96 ÷ 8 using known table facts
  • Begin to use a formal written layout for short multiplication
“Can your child work out sums like '23 × 4' or '68 ÷ 4' — either in their head using times table knowledge, or by writing it out step by step?”
