2 Grade 10 Mathematics Test The spring 014 grade 10 Mathematics test was based on standards in the 011 Massachusetts Curriculum Framework for Mathematics that match content in the grade 9 10 standards from the 000 Massachusetts Mathematics Curriculum Framework. The standards in the 011 Framework on the grade 10 test are organized under the five major conceptual categories listed below. Number and Quantit Algebra Functions Geometr Statistics and Probabilit The Massachusetts Curriculum Framework for Mathematics is available on the Department website at More information and a list of standards assessable on the spring 014 test are available at Mathematics test results for grade 10 are reported under four MCAS reporting categories, which are based on the five Framework conceptual categories listed above. The table at the conclusion of this chapter indicates each item s reporting categor, the 011 Framework standard it assesses, and the 000 Framework standard it assesses. The correct answers for multiplechoice and short-answer items are also displaed in the table. Test Sessions The grade 10 Mathematics test included two separate test sessions, which were administered on consecutive das. Each session included multiple-choice and open-response items. Session 1 also included short-answer items. Reference Materials and Tools Each student taking the grade 10 Mathematics test was provided with a grade 10 Mathematics Reference Sheet. A cop of the reference sheet follows the final question in this chapter. During Session, each student had sole access to a calculator with at least four functions and a square root ke. Calculator use was not allowed during Session 1. The use of bilingual word-to-word dictionaries was allowed for current and former English language learner students onl, during both Mathematics test sessions. No other reference tools or materials were allowed. 9
