SPANISH DOCUMENT. This guide is appropriate for 3rd, 4th, 5th, 6th, 7th and 8th grade. It was created for a lesson on mixtures and solutions as both a pre and post-assessment. At the beginning of the lesson, students answer as to whether they agree or disagree with each statement. At the end of the lesson, they do the same but back up their choice by explaining why. Students can share out their conclusions with the whole group, or the teacher can do a "mix pair share" to compare with a partner, then review the correct answers.
