Here are the math skills for grade 11, sorted by NAT score from high to low, with an analysis of the scores, as provided in the sources: (Nat=WV)

• Identify graphs that represent function data in a table: 65
• Make predictions from data in a table: 64
• Identify the effects of parameter changes on a function: 44
• Identify the equation of a function: 45
• Identify the results of an algorithm: 38
• Solve problems involving sequences with recurrence relations: 29
• Solve problems involving enumeration: 28

Analysis:

• The data suggests a notable difference in performance across the listed math skills for grade 11. Skills involving the interpretation and analysis of functions presented in tables and graphs have higher NAT scores, whereas skills related to more abstract or algorithmic concepts have lower scores.
• The skill with the highest NAT score is "Identify graphs that represent function data in a table" at 65. This indicates that students in grade 11 generally perform better when asked to match graphical representations to data sets. A closely related skill, "Make predictions from data in a table", also has a relatively high score of 64.
• The skills related to the manipulation of equations or identification of functions such as "Identify the effects of parameter changes on a function" and "Identify the equation of a function" have scores of 44 and 45 respectively. These scores suggest that students may find it more challenging to work with functions in symbolic form, or to understand how changes in parameters might affect the overall function.
• "Identify the results of an algorithm" has a NAT score of 38, which is lower than the scores for skills related to functions, but still relatively higher than the skills related to sequences and enumeration.
• The lowest scores were for "Solve problems involving sequences with recurrence relations" and "Solve problems involving enumeration" with scores of 29 and 28 respectively. This suggests that students struggle most with tasks involving more advanced mathematical reasoning about sequences, patterns, and counting problems. This could indicate a need for more focused instruction on these topics.
• The range of scores, from 65 to 28, indicates a wide disparity in student understanding and proficiency across these different mathematical topics. This suggests that instruction may need to be more differentiated to meet the diverse needs of learners.
• It is important to note that these scores are not necessarily representative of all math skills covered in the 11th grade. They do, however, give a snapshot of performance on specific skills and highlight areas where students might benefit from additional support.

**Grade 11 Math Skills Analysis and Lesson Plans**

*   **Identify graphs that represent function data in a table** (NAT score: 65)

    *   **Analysis**: This skill has the highest NAT score, suggesting that students are generally proficient at visually matching data to its graphical representation.
    *   **Lesson Plan**:
