11 × 7 = 10 × 7 + 7 = 70 + 7 = 77. The same strategy works beyond single-digit multipliers.
Try this together
Try 11 × 12 = 120 + 12 = 132; repeated digits are not the whole rule.
Say the complete fact, draw or build its groups, then try it again without the picture. It is fine to return to a known fact when an answer feels uncertain.
