The main purpose of this study is to assess effects of a previously validated fraction intervention when it is conducted classwide on the fraction knowledge of fourth-grade students with and without math learning difficulties (MLD). The study population is 4th-grade students with MLD and without MLD. Teachers agree to be randomly assigned to two conditions. In one condition, teachers include classwide fraction intervention (CFI) in their standard math program. In the other condition, teachers conduct their standard math program without CFI. CFI is implemented 2 times per week for 20 weeks for about 30 minutes each time. Students in both conditions are tested before and after CFI ends.
