This is basically the same Halloween game that the user mssamansa made, but remade from scratch for my 5th and 6th grade classes! You can check out mssamansa's Halloween Trick or Treat Quiz Game linked on the left, it's great for junior high. I don't want too much credit since I stole all of these ideas from them, but just wanted to share my version for anyone who has ES classes.
How to use:
Split students into teams and take turns letting them choose a numbered door. Click on the door specified, which will then X it out (click again on the X boards to procede to the question slide).
After the team gives an answer, you can click on the green checkmark to bring up the correct answer. For some questions, such as the "How many...?", you will need to click on the big question mark box to reveal the objects, and it will close after a short time so the students need to try and count fast! If the students answer correctly, click on the Jack-O-Lantern to reveal their prize, usually candy or sometimes a choice between a ghost (Trick or Treat) and 2 pieces of candy. If they choose the ghost, click it to reveal what they get. Sometimes they get lots of candy, sometimes only one piece or no candy, or sometimes they reveal a Zombie Attack or Vampire Fight.
For Zombie Attack, you can wipe away every teams' points. I like to just halve everyone's points, however, as in the past with Mario's Christmas Blast I've had a couple classes that get really bummed out when it's nearing the end of the game and they lose all their points. Lol
For Vampire Fight, the team can choose another team to play janken against, the winner getting 5 pieces of candy. You can change this amount, 5 felt like too much so I went with 3 instead.
All the questions are suitable for my 5th graders, as it's all grammar they should be familiar with, and it should also serve as a bit of a review for my 6th graders as well. Change the questions to fit your students' ability!
After explaining the rules, putting them into teams and giving them about 30 seconds to come up with team names, then playing the game, this activity took the whole 45-minute class period with still 12 or so questions remaining. Your mileage may vary depending on how crazy/quiet your classes are! I went through 4 or 5 rounds, and tried to finish before class ends to let the winning team get first choice of some Halloween stickers.
