The Problem

State assessment data showed only 44% of students in grades 3-5 were proficient in math. Deeper analysis revealed the gap was in number sense and mental math — students could follow algorithms but couldn't reason about numbers flexibly. When problems were presented in unfamiliar formats, performance collapsed. Teachers reported spending most of math time on procedural instruction with no time left for mathematical reasoning or discussion.

The Plan

  1. 1
    Teacher training: half-day on Number Talk facilitation
    Math coach provides a bank of daily problems organized by difficulty and type.
  2. 2
    5-min daily mental math discussion to start every class
    Teacher poses a problem. Students share strategies. No strategy is wrong — focus is reasoning, not answers.
    5 min/day
  3. 3
    Monthly number sense assessment tracked as a factor
    5 questions, 5 minutes. Data wall shows proficiency trends by classroom.
