Clarifying Activity Students use a length model to represent a division situation. The student communicates about Grade 7 mathematics through informal and mathematical language, representations, and models. Clarifying Activity Students discuss the advantages of using tables, symbols, diagrams, verbal descriptions, or graphs in solving a problem. For example, data organized in tabular form sometimes reveals patterns that are not visible in data presented in graph form. Clarifying Activity Students collect and organize information about the amount of time they spend on days during the week and days during the weekend in different activities, e.g. eating, watching television, listening to CDs, sleeping, going to school.
Students then decide on an appropriate representation for the data and justify their selection.
The student uses logical reasoning to make conjectures and verify conclusions. Clarifying Activity Students are given a set of similar triangles. Students measure the sides and angles of the triangles and organize the data to find relationships between the similar triangles. For example, the corresponding pairs of angles are congruent.
