Count pictured sets to 20, including zero; match numeral, word and quantity.
Teacher reads prompts and number words. Use the pictured counter groups where shown; their labels support numeral matching. For requested drawings, draw the exact set before pupils answer. Point to each object once; discuss missed/double counts. No speed requirement or formal addition is needed.
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.

How can we make sure no counter is counted twice?
Nine counters and six counters make 15. Stopping at 9 misses the other group.
How can we keep track while moving from one group to the other?
The picture contains 4 and 2 counters, so the last count, six, tells the whole amount. It does not make every group six.
Could we point to a different counter last and still count six?
