Essential Understandings
Concrete:
- Use manipulatives to model the function with input values. For example, y = x + 3 could be modeled with snap cubes. Given three snap cubes, adding 5 more snap cubes would give you 8.
- Use a template to identify the constant and the coefficient. For example: y = Ax + C where A is the coefficient and C is the constant. In the following example, Jane pays $3 per video every time she goes to Movies Plus. Her membership fee is $2 a visit. Given the equation y = 3x + 2, x equals the number of movies, 3 represents the coefficient and 2 represents the constant.
- Generate input values. For example, x = -1,0,1,2,3,4,5 etc.
- Use the function to generate output values based on the input values. For example: y = x + 3, when x = 5, y = 8
- Given a word problem, identify the parts of the problem that relate to the parts of the function. For example, Jane pays $3 per video every time she goes to Movies Plus. Her membership fee is $2 a visit. Given the equation y = 3x + 2, x equals the number of movies, 3 represents the cost per movie, 2 represents the fee per visit and y represents the total cost per visit.

Cluster:
Summarize, represent, and interpret data on two categorical and quantitative variables. (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. |
