Having seen her brother count to 120, Tabitha (just barely 4 years old at the time) was eager for her turn.
Those familiar with the development of counting in young children should have some strong instincts about answers to the following questions:
- How far will she get?
- Will she make any errors along the way?
- What do the answers to these questions tell us about English number language?
I’ll use this task in my math content course for future elementary teachers next fall. If you teach such a course, by all means use it and report back on what kinds of discussion it generated from your students.
