The Effectiveness of Number Sense Teaching Program on Number Sense Ability and Math Achievement of Slow Learner Students

The Effectiveness of teaching number sense program on improvement number sense ability and math achievement of first grade slow learner students was studied. The research method is semi-experimental and pre test –posttest with control groups design. Using random stage sampling method,20 girl and boy student were selected from two special schools in Tehran- Iran and devided in two equal experiment and control groups randomly.Jordan number sense test and a researcher maded math achievement test were used as research tools in all experimental conditions. The experimental group received the number sense program for 10 sessions, (each session 60 minutes ,two times for each week). Covariance analysis showe , the number sense program can improve both number sense and math achievement for experiment group(P<0.5). This findings showed that the number sense training program can improve number sense and achievement program and is a useful method for teaching slow learner students as a remedial program. Key words: number sense teaching , math achievement , slow learner students
