The practice cards and the method are different: both are CC BY-NC-SA 4.0. Copy them, adapt them, share them, as long as you say where they came from, you do not sell them, and anything you make from them carries the same licence.
The practice cards are meant to be copied. Libraries, drop-ins, union branches, colleges. Print them, put them out, no permission needed and no need to ask.
The method is published under the same terms and is more useful than it is secret. If you teach, take it.
Fonts are SIL Open Font License 1.1. The Skills England AI foundation skills benchmark that some lessons align to is published under Open Government Licence v3.0 and is cited accordingly.
