That’s a freebie coming from the Government of Canada, more specifically the Canadian International Development Agency. The map you can get is called ‘A developing world’ so I’m guessing that it shows the countries accordingly to their level of development. I wasn’t able to find an online version of the map so it’s hard for me to let you know what it looks like. But anyway, if you would like to have a map for free to help you teaching your kids, then go ahead and click on the link below as it’s totally free.
