Description: Within the context of early algebra instruction, the present study investigated whether the format in which patterns were presented had an influence on 97 grade 2-5 students' ability to work with linear generalizing patterns. Strategy choice varied significantly based on the format in which patterns were presented. Consistent with existing literature, recursion was the most frequently employed strategy, especially on the skip counting format and on near generalizations. Explicit reasoning was rarer; it was generally used by older students, for far generalizations, and on visual/geometric formats. A developmental trend was found; as students aged use of ineffective strategies decreased and explicit reasoning increased. When using explicit reasoning students rarely recognized the constant in a composite function resulting in low accuracy rates. Overall, accuracy was high for near terms, decreased for medium terms and was extremely low for far generalizations. I also examined what tools/aids students used in their problem solving.
