Professional Commentary

Students are asked to write a number sentence using multiplication to represent a word problem stated as repeated addition. This constructed-response question is a sample test item used in grade 4 in the 2003 National Assessment of Educational Progress (see About NAEP). The URL link (above) takes the user directly to the NAEP test item, with access to performance data by various subgroups of students, a scoring guide, sample student responses, and a discussion of the content on which the item is based. The NAEP website allows users to build their own printable database of test items by clicking on Add Question in the upper right hand corner of the screen. NAEP Reference Number: 2003-4M10, No. 5.
