Problem Set

This Problem Set is a part of the Lesson 3, Unit 2, Grade 7. Practice problems help students build fluency and improve accuracy when adding integers with and without the use of a number line. Students need to be comfortable with using vectors to represent integers on the number line, including the application of absolute value to represent the length of a vector. Below is a table showing the change in temperature from morning to afternoon for one week. Use the vertical number line to help you complete the table.
