The Skill Acquisition Measures (SAM) were designed by the Lancaster (Pennsylvania) School District as criterion referenced tests for mathematics. This manual consists of copies of the student test forms for level 2, with additional information for the teacher's use. Each of the test items is presented with the correct answers and the criteria for scoring. In addition, notes are provided if there are special instructions for administering or scoring that particular item. The level 2 skills relate to: (1) ordinal numbers; (2) numerals; (3) numbers (including counting); (4) the use of zero; (5) simple equations; (6) sums; (7) addends; (8) the difference; (9) the ones place; (10) the tens place; and (11) the hundreds place.
