This Instructional Activity is a part of the Lesson 15, Unit 2, Grade 6. This example is to provide students the opportunity to utilize mental math to check for reasonableness in a solution. This is envisioned to be a whole group discussion, where students can later practice solving these types of problems in the Problem Set. Allow students to collaborate with their peers to determine where the decimal point should be placed, without calculation.
