Copying and Comparing Repeating Patterns: Children’s Strategies and Descriptionshen comparing patterns. Children were presented with an AB-structured pattern in the form of a strand of beads and were asked to construct a similar strand of beads but using colors different from that of the model pattern. They were then asked to compare their strand with the one presented to them.
