I downloaded the Arctic yoga pose cards from Twinkl to match our topic. A progressive unit of work and by the end of the term the children were able to remember the names and positions of each pose without looking at a pose card. I planned this unit as a filler because we lost our indoor PE space - the children absolutely loved it and still want to do 2 terms later. As its quite generic, you can adapt it to meet your topic needs - the poses are ‘normal’ yoga poses (downward dog) but renamed to suit your topic (becomes, iceberg) - so you could even do that. Downward dog could become downward tiger for example.
