Reading and writing numbers to 120

Count to 120 starting at any number less than 120; read and write numerals to 120

Lesson

Set out your lesson

Read, write and continue numbers across a hundred.

Before teaching

Activity

Ask the learner to explain one prerequisite idea before starting. If uncertain, revisit it; graph order is not learner readiness.

Policy

Check readiness rather than assuming source graph order establishes attainment.

Printer, credit, and teaching notes

Instructions

Use numeral cards on screen. The adult reads Try dictation from the separate key, not the learner card.

No Printer

Use the supplied stage cards on screen or scrap paper; adult key stays separate.

Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.

What this lesson covers and its limits

These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.

partial: Count to 120 starting at any number less than 120; read and write numerals to 120
Bounded objective: Read, write and continue numbers across a hundred. Long count and selected numeral samples only; dictation support must be recorded. Exact 108 and 115 have been modelled.
partial: Count from 47 to 120 without errors
Full 47–120 count opportunity; only actual performance can establish error-free count.
partial: Read the numeral 108 correctly
Reading 108 modelled, not fresh assessment.
partial: Write the numeral for one hundred and fifteen
Writing 115 guided; separate unfamiliar dictation in T does not erase support.
partial: Can {{name}} start counting from any number up to 120 — for example, starting at 87 and counting up to 120 without losing track?
Try offers extended-counting-and-unrehearsed-dictation for the bounded objective; it does not establish every part of the source assessment. Long count and selected numeral samples only; dictation support must be recorded. Exact 108 and 115 have been modelled.

Hundred Chart Digit Game

Before you open · source notes

Digit cards and a hundred chart help place and name numbers to 120. Use it for reading and writing numbers, not every place-value regroup.

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 place a two-digit number on the chart and say it aloud. One game does not prove every number to 120.

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.

Count from 47 to 120 without errors
Read the numeral 108 correctly, e.g. by finding it on a number chart continued past 100
Write the numeral for one hundred and fifteen

“Can your child start counting from any number up to 120 — for example, starting at 87 and counting up to 120 without losing track?”
