abstract = {Summary: This study compares six 7th grade Israeli mathematics textbooks, examining the opportunities provided by the textbooks to justify and explain mathematical work, in two central topics: equation solving and triangle properties. Using two different units of analysis, initial findings reveal that all six textbooks included considerably larger percentages of geometric tasks that required students to justify or explain their solutions than such algebraic tasks. Moreover, considerable differences were found among the six textbooks in the percentages of tasks that required students to justify and explain in both topics, more so in the algebraic topic. Analysis of the nature of the student tasks -- whether the tasks include a given mathematical claim for the students to justify or not -- also revealed substantial differences among the textbooks.},
