Abstract
In recent years, the Peruvian education system has vastly improved its coverage, reaching populations that previously had no access. Unfortunately this increase in coverage has not resulted in the same improvement in educational quality, and mathematics are an area where Peruvian students are particularly lacking. Nation wide tests show every year that only 13.2% of 7 years-old have achieved the expected level for their age in mathematics abilities. Geographic disparities in this regard are important, since in rural areas this percentage only reaches 3,7%. Previous research has shown that interventions at a very early age can have the greatest impact on learning but also on long-term indicators of income and well-being.

The program evaluated is a hands-on mathematics learning method for 5 year-old students in kindergarten, mainly based on the discovery of mathematical concepts through games, group or pair activities.

The program has been implemented in 2012 in two of the poorer Peruvian region, Ayacucho y Huancavelica. The evaluation process was a clustered randomization, at the school level. Schools were affected to either treatment or control groups within geographical strata corresponding to the administrative unit they belonged to and their location (rural or urban). It has been evaluated using RCTs methods estimating the impact of the program in short and medium term. A first impact evaluation, an end line study, has been developed at the end of the kindergarten school year right after children received the program and a follow-up analysis has been developed a year later at the end of first grade school year.

To assess the effect of the mathematical program, we developed a math test to measure children abilities in math and a written and oral communication test to measure possible spillover effects.

The evaluation shows encouraging results in short run as children in treatment group performed better with respect children in control group. In medium term no statistically significant results has been found.

Experimental Details
Interventions
Intervention(s)
The program is designed to be taught in sessions of 45 minutes at a time, 2 or 3 times a week. Sets of materials (an individual box per student containing games and learning materials) was handed out to all schools receiving the treatment, and teachers were trained on how to organize the teaching sessions and direct the activities (during 1.5 days of training at the start of the program). Discussion groups of teachers were organized during the year (4 in total) to discuss pedagogical methods and the implementation of the program. In addition, parents' meeting were organized during the year to discuss about program's workplan, activities, and incentivizing parents to ask sons about their daily school experience.

Experimental Design
Experimental Design
Theory of change: 1) Need: children attending kindergarten does not have sufficient preparation to be enrolled in primary school, mostly in mathematics; 2) Input: the implementer develop an experimental math's program with new pedagogical model, educational material, training and teacherĀ“s accompaniment, and parents' involvement; 3) Output: teachers feel trained in teaching math supported by new educational material and parents are more involved; 4) Outcomes: the program improve quality of education and children learn more; 6) Goal: children are more qualified in math and it reduce their dropping out of school and in the long run they improve their incomes.

The population under study is 5 years old student in kindergarten in two departments, Ayacucho and Huancavelica, Peru. The areas of intervention are based on three provinces (Huancavelica, Huamanga and Angaraes) with greater school density and greater number of children enrolled per district. Schools with less than 6 children with 5 years old are excluded from the evaluation. The sample is divided in three provinces, so first province stratification. Next, in each stratus there has been a further stratification: urban and rural area. Resuming five stratus has been considered: urban/rural-Huancavelica, urban/rural-Huamanga, rural-Angaraes (in this province there are not rural areas).

Children has been tested two times: the first time right after receiving the program at the end of kindergarten school year (short run effect of the program) and secondly a year later when they enter in primary school (medium term impact of the program).
