We invited all schools in Rio de Janeiro municipality with one or two 5th grade classes to a meeting to explain the research objectives. From all the 395 schools with one or two 5th grade classes in the city in 2019, 252 schools showed up in the meeting and 178 schools accepted to participate in the research. Of the 178 schools that chose to participate, we randomly selected one group – 50% of the sample or 89 schools – to receive the treatment and 50% to serve as the control. Of the 89 schools receiving treatment, 82 had teachers attending the workshop (intervention) at least once.
