This week we focused on Order of Operations without exponents. I developed a great activity that allowed students to analyze different problems while looking for mistakes. I instructed the students that they were human lie detectors 🙂 . Students determined if the statements where Truths or Lies. Students worked through each problem justifying why the problem was a Truth and why the problem was a Lie. They sorted the cards onto the sorting mat which has QR codes to reveal the correct answers.
