Year-end portfolio and transfer assessment
Use unfamiliar problems involving addition, subtraction, tens and ones, number comparison, measurement, time, data, and shapes. Score independently demonstrated skills separately. Keep work and scores private. A full Alabama mathematics standards crosswalk and instructional review are still required.
