This paper focuses on elementary school students' use of mathematically-based (MB) and practically-based (PB) explanations. The mathematical context used in this study is multiplication. Two issues are discussed. The first issue is a comparison between MB and PB explanations used by students before they are formally introduced to multiplication in school as opposed to the explanations they use afterward. The second issue is a comparison of the types of explanations used for multiplication without zero as opposed to explanations used for multiplication with zero. Results show that more students use MB explanations than PB explanations. However, when multiplying with zero, many students use another type of justification (ie. rule-based explanation).
