Description:
This packet includes a worksheet for students to practice comparing decimals. In the packet, students are asked to chart decimals numbers from least to greatest. They are also challenged to explain how to compare decimal numbers in a written explanation question. In my own classroom, I have used this as a formative assessment for students to complete independently.

This packet also includes a poster project. This is a great opportunity for students to explain how changing how atomic masses are rounded could affect the outcome of scientific experiments. In my classroom, I have used this as a summative assessment for students to complete in small groups or with a partner. By working with a partner, students are practicing verbalizing different ways to solve problems and practicing using critical math vocabulary.

Objectives:
Students will compare numbers to the thousandths place by recording <, >, or =.
Students will explain how to compare decimals by using place values terms and inequality vocabulary.

Please note: The atomic masses of these elements are not accurate. They have been changed to better suit the standards.
