## Welcome, Eighth Grade Math Teachers.

This is an explanation of the cluster organization including links leading to the NC2ML Collaborative for specific resources.

The clusters are recommended using the progression in the framework, but this is not the only possible progression teachers may use. Please look to the “Connections & Rationale” for notes about when one cluster must follow another, if another progression is desired. Also, continue to focus on how the Standards for Mathematical Practice can be incorporated with these content clusters. If considering changing the order of the clusters, we suggest keeping most of the sequence with the following two alternative orderings.

**Recommended Order:**

Reasoning about Similarity and Transformations Cluster

Functional Reasoning Cluster

Reasoning about Equations and Angles Cluster

Statistical Reasoning Cluster

Reasoning with Rational/Irrational Numbers (and Pythagorean Theorem) Cluster

Reasoning about Exponents/Scientific Notation Cluster

**Alternative A**:

Reasoning about Similarity and Transformations Cluster

Functional Reasoning Cluster

Statistical Reasoning Cluster

Reasoning about Equations and Angles Cluster

Reasoning with Rational/Irrational Numbers (and Pythagorean Theorem) Cluster **

Reasoning with Exponents/Scientific Notation Cluster**

** Real numbers and exponents units can be switched according to your preference

**Alternative B:**

Reasoning about Similarity and Transformations Cluster

Reasoning about Equations and Angles Cluster

Functional Reasoning Cluster

Statistical Reasoning Cluster

Reasoning with Rational/Irrational Numbers (and Pythagorean Theorem) Cluster **

Reasoning with Exponents/Scientific Notation Cluster**

** Real numbers and exponents units can be switched according to your preference

Please pay attention to the “Supporting Standards” and “Connections & Rationale” portions of this recommendation. These tools should help to connect mathematical concepts across the units, and to highlight potential opportunities for revisiting previous units’ main ideas.
