# Access Point #: MAFS.912.F-LE.1.AP.1bArchived Access Point

In a linear situation using graphs or numbers, predict the change in rate based on a given change in one variable (e.g., If I have been adding sugar at a rate of 1T per cup of water, what happens to my rate if I switch to 2T of sugar for every cup of water?).
Clarifications:

#### Essential Understandings

Concrete:

• Model rate of change using tools or manipulatives.
• Model increasing/decreasing rate of change in a problem using tools or manipulatives.
• Model rate of change using a graph.
• Model increasing/decreasing rate of change in a problem using a graph.
• Match the change in the variable to the change in the rate given the situation.
Representation:
• Identify the rate of change in a problem.
• Compare and contrast two rates of change on a graph.
• Compare and contrast two rates of change in a display.
• Understand the following concepts and vocabulary: rate of change, variable, increase, decrease, linear.
General Information

Category: Access Points
Cluster: Construct and compare linear, quadratic, and exponential models and solve problems. (Algebra 1 - Supporting Cluster) (Algebra 2 - Supporting Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
