MathStart 2: Tally O'Malley (Tallying)

The O'Malleys are driving to the beach for vacation. Eric, Bridget, and little Nell are getting bored in the back seat, so Mom suggests a Tally game. They decide to count cars on the highway. Each of the kids picks a color - silver for Eric, blue for Bridget, and red—always red—for Nell, while Mom sets the timer. Eric trounces the competition and gets to wear the Shamrock medal. And his sister dubs him "Tally O'Malley!" But will he be able to hang on to the title when they tally t-shirt colors while waiting in line for ice cream, or tally train cars? Tally marks are a useful tool for children to keep track as they count, and for data collection. Grouping tally marks also reinforces counting by fives. Used with permission from Stuart J. Murphy.
