Giving simple experience with probability to children of this age can extend their understanding of the need for fraction in everyday life. If the correspondence of equal chances to equal parts of a figure is emphasized. then fairly difficult problems can be approached through diagrams. The following activities involving probability and combinations build on language-arts experiences and incorporate concepts in multiplication. graphs, and fractions.
The topic of coordinate graphing is often introduced as an isolated textbook topic for students in the third grade. Children's current fascination with stickers can be incorporated into an inte resting approach to graphing in the middle elementary grade.
