Preschool Busy Book, 30 Montessori Activities With Markers

Thirty pages of colours, numbers, letters and shapes, and a marker that wipes off so it can all be done again tomorrow.

The pieces are velcro. She pulls the orange one off its page and puts it on the orange fruit. She matches the number four to four apples. She traces the line, you wipe it, she traces it again.

That is the whole thing, and it is why twelve different mothers filmed the same book without knowing about each other. One of them put it plainly: her toddler goes and gets it herself, to learn.

Dry-erase markers included. From 18 months, and it keeps working right through preschool.
