Common student mistakes
Build distractors and reteach prompts around the errors students actually make on this standard.
- 1Treating the equal sign as 'the answer goes here' (e.g., solving 8 = 6 + ___ as '14').

- 3Struggling with equations where the unknown is on the left (e.g., ___ + 3 = 8).
Teacher FAQ
Why does the equal sign trip up so many students?
Years of seeing the equal sign followed by 'the answer' (e.g., 5 + 3 = ___) trains a procedural reading. CCSS 1.OA.D.7 explicitly fixes this by introducing equations in non-standard formats. Use balance scales and 'both sides are the same' language from day one.
