I made a 3-hint quiz with silhouettes (think the "Who's that Pokemon?" insert cards from the original Pokemon series - no trick answers like a Jigglypuff viewed from above lol) of various characters to practice be動詞 in the style of the dialogue in NC 1 on page 60. The 3 hints come up first one by one, then the silhouette as an extra hint.
I'm based in Okayama so 2 answers are of famous individuals in this area. You might want to change them - along with the LE SSERAFIM one if your kids aren't into k-pop.
To make an image into a silhouette on ppt go to format picture, select the colour section, and put sharpness on full, brightness on -100, and contrast on full.
Happy reviewing!
