Content Area: Math
Index: 4.3C Grade 5 CPI 2
Standard: 4.3 - Patterns and Algebra
Strand: C - Modeling
Cumulative Progress Indicator: 2 - The student will draw freehand sketches of graphs that model real phenomena and use such graphs to predict and interpret events (e.g. changes over time; rates of change · Changes over time · Rates of change (e.g., when is plant growing slowly/rapidly, when is temperature dropping most rapidly/slowly)
Grade: 5
Sample Activities:
· Students investigate graphs without numbers. For example, they may study a graph that shows how far Yasmin has walked on a trip from home to her friend's house and back, where time is shown on the horizontal axis and the distance covered is on the vertical axis. Students tell a story about her trip, noting that where the graph is horizontal, she has stopped for some reason.
· The student will draw freehand sketches of graphs that model real phenomena and use such graphs to predict and interpret events (e.g. changes over time; rates of change (e.g., when is plant growing slowly/rapidly, when is temperature dropping most rapidly/slowly)
· Students are presented with a graph representing a student's monthly income from performing lawn care for people over the past year. The graph shows no income during the months of November, December, and March. They write a story which explains the behavior of the graph in terms of the need for services over the course of the year.
