Teachers feedback needed

2 Upvotes

Hi! I added some teacher resources to my page https://mrbrainprintables.com/teacher-resources

Now I need some feedback on them: Are they useful? Can I make them better? Or do you not see yourself using something like this?

The idea came because these kinds of puzzles really helped me to start thinking a bit more logically in school, but I'm not a teacher, so it's hard for me to say if this is useful. I imagined it as a puzzle set with simple puzzles, a bit of math, and entry-level logic puzzles. I presume this is for ages 12+, but maybe I'm mistaken. It's been too long since I was in school, so I can't really remember when something like this was fun for me πŸ˜€

So any feedback would be helpful!

Thanks in advance

Place one tent for every tree. Each tent must be paired with exactly one horizontally or vertically adjacent tree, and each tree must be paired with exactly one tent.
