Young Children's Understandings of Length Measurement: Evaluating a Learning Trajectory
Peer reviewed Peer reviewed
Direct linkDirect link
Szilagyi, Janka; Clements, Douglas H.; Sarama, Julie – Journal for Research in Mathematics Education, 2013
This study investigated the development of length measurement ideas in students from prekindergarten through 2nd grade. The main purpose was to evaluate and elaborate the developmental progression, or levels of thinking, of a hypothesized learning trajectory for length measurement to ensure that the sequence of levels of thinking is consistent…

Mitchelmore, Michael C.; Papic, Marina M.; Mulligan, Joanne T. – Journal for Research in Mathematics Education, 2011
The development of patterning strategies during the year prior to formal schooling was studied in 53 children from 2 similar preschools. One preschool implemented a 6-month intervention focusing on repeating and spatial patterns. Children from the intervention group demonstrated greater understanding of unit of repeat and spatial structuring, and…
