How I Use It
I use this on our school's iPods as an AM duty hallway activity as students wait to enter their classroom. Students take turns doing rounds and pass the iPod to the next person to do an additional round. Teachers use it for station rotations during class time for extension or remediations.
My students really like this app. They are familiar with the process because we use FasttMath, another product created by the same developers. The monsters are fun looking rather than scary and I love the fact that the students have to use their logical skills to match the equations, rather than choose answers.
