@grant.haverford: Counting trick for Grades 3–5: three-digit numbers from 2, 4, 6, 8 with no repeated digits give 4 × 3 × 2 = 24. Allow repeats and it becomes 4 × 4 × 4 = 64. Ask: which choices remain after each pick? From p. 33 of Grade 4 Foundation: Workbook for the AMC 8, by Grant Haverford. I created this independent practice workbook.
