Student teams battle one another by skip counting by different numbers and switching their counts when the teacher shouts, “Switch!” This game promotes numerical fluency, numerical pattern recognition, and addition/multiplication operations. Postscript items are designed as rich grab-and-go resources that teachers can quickly incorporate into their classroom repertoire with little effort and maximum impact.
