Independent, self-paced Classified Nomenclature Exercise derived from the group lesson of the science study of the Circulatory System of the Human Body presented with the three-dimensional model (see item SCIENCE-A49) and the control booklet from this exercise. This product consists in studying the nomenclature of the organs of the human body involved in the Circulatory System using picture/label matching for the Junior Elementary Level (ages 6-9) and matching reading story cards to pictures for the Advanced Elementary Level (ages 9-12). A control booklet is included. Like all nomenclature exercises, the material lends itself well for multiple Montessori presentations with the Three-Period-Lesson and for independent individual work involving tracing, coloring and writing main summary sentences so that a student may make one's own illustrated control booklet to take home when finished. Students should be allowed to repeat the same work as many times as desired. All full colored pictures are light box compatible.
