Yay for forever freebies! Celebrate Halloween with this ghostly Halloween Games. Students practice subtracting within 20. Animations include a revolving door that reveals the answer and funny ghost faces. There are 20 questions and you just click on each question to go to it. The question disappears after you’ve clicked on it so you know you’ve answered it. There is a type-in scoreboard. The scoreboard can be typed in during Slideshow Mode. Great for a guided math center or Halloween activity. Great for individual practice on the iPad!
