About this worksheet
10 times the number plus 2 times the number: 12 × 7 = 70 + 14. Children who know their 10s and 2s can derive every fact. Every answer is even; the units digits run 2, 4, 6, 8, 0 and repeat. The facts that need the most repetition: 12 × 6 = 72, 12 × 7 = 84 and 12 × 8 = 96, where the derived sum takes a moment.
Typical use: grade 3, one sheet a day for a week, then a mixed 0–12 sheet to check the 12s hold up among the other tables. Narrow the range to 1–10 for a shorter table, or switch to the horizontal layout for a fact-test format.
Standards
- Common Core 3.OA.C.7 — fluently multiply within 100
- Common Core 3.OA.B.5 — properties of operations (commutativity: 12 × a = a × 12)
