Adding Instead of Multiplying: If students struggle with adding regrouped digits first before multiplying, teach them the rhythm: "Multiply first, then add the helper!" Misaligning Columns: If students' handwriting drifts, have them use standard grid paper, or utilize the aligned dashed columns printed directly on the Zero Hero worksheets!
