1. Standard At A Glance

Standard: MATH.12.S-CP.A.3

Short description: Understand the conditional probability of A given B as P(A and B)/P(B), and interpret independence of A and B as saying that the conditional probability of A given B is the same as the probability of A, and vice versa.

2. Typical Indicators

Tier 1

Use short daily routines tied to real reading, writing, or real-world application at home.

Tier 2

Provide targeted guided practice in 10-15 minute sessions with clear examples.

Tier 3

Use individualized practice with explicit modeling and frequent feedback.

5. Modifications

Diverse learners: use visuals, sentence supports, and language scaffolds.
Disabled learners: adapt response format, pacing, and access supports as needed.

6. Cross-Curricular Integration

Connect to real-world applications of statistics, probability, and trigonometry — data, finance, engineering — at home.
