   Crossing ten with pictures

   Choose a sensible addition strategy within 20 using partitioning.

Using it in class

Teacher reads prompts. The screen supplies the pictured counter groups where referenced. Draw ten-frames when requested. Discuss moving counters without adding new ones, making ten, then counting the unused part. Multiple strategies may work; each question specifies the one to examine.

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.
