Grade 4. Students explore more complex repeating and growing patterns, which leads to writing general rules to find elements in the nth position. They use equations to represent realtionships and letters or symbols to represent unknowns. Functional relationships are investigated.
After collecting change-over-time data, students display it in graphical form. Data displays include tally tables, line plots, bar graphs, and line graphs. The mean is introduced and used to analyze data along with range, mode, and median. Writing about mathematical thinking is an integral part of the lessons.
