Lab Record Books of Classes I & II contains 20 experiments and those of Classes III to X have 25 experiments. Each experiment has to be done using APOTHEM Math Learning Instruments either as a pre-lesson or as a post lesson. The Lab Record Books are graded to fulfill NCERT, CBSE, ICSE and all State Board curriculums of Class I to X. The Lab Record Books are structured to develop children's positive personality traits including confidence and self-esteem.

To do an experiment, detailed step-by-step instructions are given in every Lab Record Book. Yet, primary class children will not be able to read and do the experiment on their own, so step-by step instructions have to be told by the teacher. Moreover, the teacher should allow the students to explore the APOTHEM Math Learning Instruments; only then the required instructions should be given. Students should be encouraged to think on their own, discus among themselves and then do the experiments.
