Common student mistakes

Build distractors and reteach prompts around the errors students actually make on this standard.

• 1Adding instead of subtracting when the word problem uses 'altogether' or 'in all' — and vice versa.
• 2Drawing the picture but losing the count when combining groups.
• 3Writing the equation backwards (e.g., 5 = 3 + 2 instead of 3 + 2 = 5) — note: this is actually correct, but it confuses students who only see one form.
