Nesse trabalho objetivamos analisar quais criterios de congruencia sao conservados em quinze problemas com equacoes do primeiro grau apresentados em um material didatico apostilado e tecer reflexoes sobre a influencia dos criterios nao conservados nas possiveis dificuldades dos alunos. Essa e uma pesquisa bibliografica e documental e seu desenvolvimento apontou o baixo indice de conservacao da correspondencia semântica das unidades de significado e o alto indice de conservacao da univocidade semântica terminal nos problemas analisados. Alem disso, os dados levantados apontam para a necessidade de se ampliar as analises ja realizadas nas pesquisas desenvolvidas, considerando a variedade de tipos de problemas de 1o grau. In this work we aim to analyze the congruence criteria what are conserved in fifteen problems with equations of the first degree, in a didactic material and reflect on the influence of criteria not conserved in the difficulties of the students. This is a bibliographical and documentary research and its development pointed the low conservation index of the semantic correspondence of the units of meaning and the high conservation index of the terminal semantic univocity in the analyzed problems. In addition, the data gathered point to the need to expand the discussions performed achieved in the researches developed, considering a variety of types of problems of the first degree.
