Big Ideas: Numerical patterns can be graphed on the coordinate grid. Two numerical patterns can be compared by looking at corresponding terms.
This lesson builds on students' work with patterns and graphing on the coordinate grid. The task asks students to compare the growth of two trees over time using a model. The lesson pushes them towards using a graph as a way to model patterns and to compare two numerical patterns. The mathematical concepts in the lesson build towards students' future work with graphing functions in later grades.
Vocabulary: ordered pairs, numerical patterns, x-coordinate, y-coordinate, table (t-chart, input/output, function table), correspond
