The purpose of this action research is to determine the effect of instruction on basic addition fluency. The Number Corner curriculum was used to instruct, supplement, and assess students’ ability to increase their addition facts per minute. A sample of 22 students participated in this action research study. There were several programs including Scout Them Out, Quick Facts, and other activities assigned by the curriculum, that helped make up the whole intervention. This took place in scheduled increments over a three-month period. The study gathers qualitative data which helped determine that the curriculum was successful in helping students increase their math facts per minute, and aids in increasing basic addition fact fluency.
