How to help your child with Class 3 Computer
- Name things as you use them. Point out the keyboard, the monitor, a folder or the address bar when your child is at a computer or phone.
- Turn routines into algorithms. Ask your child to give step-by-step instructions for brushing teeth or making a sandwich, in the right order.
- Talk about safety early. Never sharing passwords or personal details is the most useful computer lesson of all.
- Try a free block-coding app together. Dragging blocks to move a character makes sequence and loops click.
