Trapped in a haunted house! Teams revise number and algebra across seven spooky rooms: negative numbers, order of operations, fractions and percentages, substitution, simplifying and expanding, solving equations, and sequences. Each room’s four answers add up to a total whose last digit unlocks part of the front door, so one wrong answer means a wrong code. Includes 13 illustrated slides with notes, a 5-page escape booklet with a lock and room tracker, a Ghost Challenge extension, a full answer key and a teacher guide. All PDFs in A4 and US Letter.
