1 Grade 2 SRPSD Common Math Assessment

2 Instructions Administering the Assessments 1. This assessment has been developed with the intention of being split up into individual outcomes and given upon completion of instruction/units throughout the year and not as a comprehensive test in June. 2. The division expectation is for the assessment to be given as both a pre (formative) and post (summative) assessment which will be entered into SRPSD database. 3. Use professional judgment on whether this assessment is given orally or in written form. The intent is to assess mathematical understanding. 4. Refer to the last few pages for any paper manipulatives needed to administer certain questions. Teachers will have to print off a copy for their class. 5. Calculator use is only allowed where indicated. 6. In the case that a student answers a level 4 question correctly but misses the level 2 or 3, the teacher will need to: a) reassess b) use professional judgment (teacher knows student best). 7. This assessment is not intended to assess ELA reading or writing outcome s therefore questions can be read to students and answers can be scribed when needed. 8. The corrected pre-tests are not to be showed to the students as it will affect post -test results. Page 1
