UKMT Junior Maths Challenges practice ppts

I have taken the time to go through some old UKMT Junior Maths Challenge papers, put them onto slides, and use them to coach groups that have either never seen Maths Challenges before (Y7s, some Y8s, even 9s) or want to brush up their skills at interpreting puzzle style questions.
They can be used as starters for higher end groups at beginnings of lessons when students enter the room, just to get their brain juices flowing, or in any way you see fit.
**Obviously not charging as it is not my work at all, but i do find them easier to use with classes in Powerpoint form, rather than printing out all the time. I will over time be adding more to this stash, as I go through them all. Hopefully you will find them as useful in this format as I do.
Powerpoints both Questions only, and with Answers (and boundaries) are included.
