The purpose of the study was to develop and investigate the effectiveness of a short instructional program to enhance mental computation strategies (addition and subtraction) in two classes of Year 3 students (approximately 8 years of age). Outcomes of the project were aimed at benefiting both the teachers and the students. The short instructional program made use of two models (100 board and empty number line) to support students' development of mental strategies. Pre-instruction and post-instruction interviews were conducted to monitor students' progress.
