This paper reports how Japanese grade 6 students use a "find a pattern" strategy for solving both non-routine word problems and pattern finding problems and what obstacles they face when executing the strategy. Twelve grade 6 students, who were taught the "find a pattern" strategy, solved two types of problems and their solution strategies were analyzed. After teaching of strategies, high achievement level students learned to use the "find a pattern" strategy more easily than middle and low achievement level students for solving both types of problems. But middle and low achievement level students came to use the "find a pattern" strategy only on pattern finding problems. Some obstacles to use of the "find a pattern" strategy were identified.
