Use a regular wall map to display digital photos, perhaps photos of where the children live, their rooms or the like.
The procedure will then be:
- Get a wall map.
- Send home an iPad, or similar with the children and let them (or the guardians) take photos of the house they live in, their room, a stuffed animal or the like.
- Save your pictures to OneDrive.
- Create a link to each image.
- Create QR code, for example on QRcodeMonkey.
- Put a needle where the child lives and pull a thread from there to the QR code.
The result could be something like this:
(The QR code shows where my desktop is located.)
