Numerals and quantities
Connect written numerals 0–20 with sets, including teen quantities.
Using it in class
Read directions aloud and point to number choices. Keep numeral choices visible; children can respond by pointing. Printed marks and explicitly described sets are the evidence. A vertical line separates groups, not extra objects. Model actual numeral writing after selected questions.
Give everyone time to think and discuss before one pupil acts at the board. The class explains and confirms together; hints and explanations stay until you move on.
Use an up-to-date browser on a computer connected to a whiteboard or shared display. Touch, mouse and keyboard; optional audio and reduced motion. No pupil accounts or personal devices.
Choose from 5 challenges up to the full activity. Discussion determines the duration: you set the pace.
A look inside the activities
Teacher: point to 16 and say “sixteen.” Which plan makes a set that matches this numeral?
- Put one object beside six objects and stop.
- Count out sixteen objects, one at a time.
- Count out fifteen objects and stop.
Explanation and discussion
A set of sixteen matches 16. One object with six objects makes only seven; treating the digits as separate sets loses the numeral’s meaning.
Make the sixteen-object set in a row and label it.
Teacher: read aloud. One box is empty. Another contains ● ● ●. Which pair labels the empty box, then the dot box?
- 0, then 3
- 1, then 3
- 3, then 0
Explanation and discussion
The empty box has zero dots; the other has three. Matching 0 and 3 in that order labels both sets accurately.
Teacher: draw the boxes and let children attach both numeral cards.
