Exploratory Study of Children's Multi-digit Multiplication and Division

Despite its importance, there is little research on children's use of and reasoning with different approaches to multiply or divide multi-digit numbers. This three-year exploratory project will: (1) examine and document the range of strategies children use to solve multi-digit multiplication and division tasks; (2) examine students’ exposure to and teachers' use of different approaches to multi-digit multiplication and division, as well as the effect of such approaches on children’s mathematics; and (3) explore how eye-tracking data and gesture is associated with children's strategies when solving multiplication/division tasks. 

This poster reports preliminary analysis from Year 1 data collection, with a focus on the 4th grade dataset.
