Year 6 students' idiosyncratic notions of unitising, reunitising and regrouping decimal number places
Baturo, Annette R. & Cooper, Thomas J. (2000) Year 6 students' idiosyncratic notions of unitising, reunitising and regrouping decimal number places. In Nakahara, Tadao & Koyama, Masataka (Eds.)

Having flexible notions of the unit (e.g., 26 ones can be thought of as 2.6 tens, 1 ten 16 ones, 260 tenths, etc.) should be a major focus of elementary mathematics education. However, often these powerful notions are relegated to computations where the major emphasis is on "getting the right answer" thus procedural knowledge rather than conceptual knowledge becomes the primary focus. This paper reports on 22 high-performing students' reunitising processes ascertained from individual interviews on tasks requiring unitising, reunitising and regrouping; errors were categorised to depict particular thinking strategies. The results show that, even for high-performing students, regrouping is a cognitively complex task. This paper analyses this complexity and draws inferences for teaching.
