I found this website with somewhat easier logic puzzles. https://www.woojr.com/printable-logic-puzzles-for-kids/
Both my 5 year-old and 7 year-old like them. The 7 year-old started writing her own puzzles. I am not sure whether it is because they like puzzles or because they are currently very bored. We got a package yesterday and they spent a good part of the morning playing with the cardboard. They made a fort, then painted the cardboard (there were patterns on the outside) and saving it so they can paint the inside tomorrow. The other day, they asked to have the old empty tissue box. And the empty jug of milk.
I will come back with more activities. We did skip mathclub today.
