This paper deals with LOs for mathematics of 11–12 class students. LOs from the national learning objects metadata repository have been selected. The discussion has been focused on three aspects: 1) how many LOs are there of 11–12 class students, search problems; 2) investigation of content provided in LOs; 3) investigation of interaction between learning content and students activities. It is found that LOs are poor in use of advanced interaction between content and students activities.
