Lesson objective: Represent and solve real world and mathematical problems by graphing points in the coordinate plane.

This lesson provides an opportunity for students to apply their knowledge and understanding of representing and solving real world and mathematical problems using the coordinate plane. Students are asked to graph and analyze information about the weight of female giant pandas during their first eight years of life.

Key Concept students will use:

• The coordinate plane can be used to represent problems and situations.

Skills students will use:

• interpret coordinate values of points in the context of a situation
• identify and plot ordered pairs on a coordinate plane

Students engage in Mathematical Practice 2 (Reason abstractly and quantitatively) as they create ordered pairs from two number patterns and interpret the coordinate values in the context of a real-life situation.

Key vocabulary:

• coordinate plane or grid
• coordinates
• ordered pairs
• x-coordinate
• y-coordinate
• x-axis
• y-axis

Special materials needed:

• graph paper
• pre-printed coordinate grids
