Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

What Are the Treatments Tested in This Trial?

Interventions

  • Arithmetic strategy training
  • Speeded practice training

Trial Overview

The study compares two types of training: one that helps kids practice solving math problems quickly (speeded practice), and another that teaches different strategies for doing arithmetic. The goal is to see which method better improves math skills.
