This is a fully interactive math sequencing game. Each riddle requires a student to do simple addition and subtraction, or know what numbers come before or after give numbers in order to find the answer to the number riddle. This is a whole class activity that can be easily run on any computer project or interactive whiteboard. Furthermore, I often give my students access to a 100's chart so they can refer to it if need be.
This set uses numbers up to 100.
