Help students deepen their understanding of place value through the thousands by finding mistakes. There are 12 task cards included in which students determine the correct answer and find a mistake.
On each card, students will read a question. On the cards "Student A" and "Student B" both provide answers. Students in your class will get "to be the teacher" when they assess both "Student A" and "Student B." Students not only need to decide who was correct and who wasn't, but they also need to explain the mistake made. Through explaining others' mistakes, students can deepen their own understanding.
