Rigor and Mathematical Practices

2d

Indicator 2d

The three aspects of rigor are not always treated together and are not always treated separately. There is a balance of the three aspects of rigor within the grade as reflected by the standards.

Evidence shows all three aspects of rigor are present both independently and in combination. E3 and E4 describe distinct activity types devoted separately to developing a concept, mastering a procedural skill, or applying mathematics, while E6 explicitly states the three aspects are interconnected (procedural fluency supported by understanding, application requiring both) and E11 shows anchor contexts integrating concepts with application. The 'Putting It All Together' units (E10, E12) and end-of-grade in-depth application problems (E5) demonstrate the three aspects engaged simultaneously to consolidate understanding of a single topic across the grade, with E1 naming an intentional 'Balancing Rigor' design.

Cluster Meeting

Consider the following question(s) as evidence is synthesized:

● How do the materials include multiple routine and non-routine applications throughout each grade?

● How do the materials provide opportunities for students to independently demonstrate multiple routine

and non-routine applications throughout each grade?

● Do the materials have a consistent lesson structure for including multiple routine and non-routine

applications?

● Based on the student-facing materials, how do students independently demonstrate multiple routine and

non-routine applications?

Gateway 2: Rigor & Mathematical Practices

Criterion 2.1 Materials reflect the balances in the Standards and help students meet the

Standards’ rigorous expectations by giving appropriate attention to:

developing students’ conceptual understanding; procedural skill and fluency;

and engaging applications.

Indicator 2d The three aspects of rigor are not always treated together and are not always

treated separately.

About this indicator:

What is the purpose of this Indicator?

This indicator, along with 2a, 2b, and 2c, determines the shift of Rigor. In order to be considered rigorous,

program materials must include a balance of conceptual understanding, procedural skills and fluencies, and

application as reflected in the standards.

---

hift of Rigor. In order to be considered rigorous,

program materials must include a balance of conceptual understanding, procedural skills and fluencies, and

application as reflected in the standards. This balance should be evident in all aspects of the grade level to

support students as they develop mathematical understanding.
