Phase:
During/Explore/Explain
Activity:
Students will explore using a digital number line to solve real-world problems that include rational numbers. The digital number line offers many settings that include negative values, decimals, integers, and fractions. Students will work through an example problem with detailed instructions to become familiar with how to change the settings on the number line. Students are then provided five additional problems to complete. Optional number line settings are included for each problem. Have each student complete the first problem independently. At this point, the teacher should conduct a Think-Pair-Share with the class. Each student should have a partner. Ask the students to work with their partners to compare their two number lines to determine if the models and number sentences are the same or different. Allow each group to share their results and reasoning with the rest of the class. Students can then answer the remaining questions using their digital number line. Since the digital tool can create a link to share their number lines, the students can easily send this information to the teacher. For an extension or additional practice, students can be asked to write their own real-world problems and then create a model for their problem. The problems could also be exchanged with other classmates.
Assessment Strategies:
Have students complete an exit slip explaining if they found the digital number line helpful while solving the word problems.
Through the link provided from the student, evalute the student's digital number line used to solve the real-world problem.
Advanced Preparation:
Visit the Digital Number Line Tool to become familiar with how to use the tool.
Students will need online access to the digital number line.
Copy the “Using Number Lines to Model Real-World Problems” student response page.
Variation Tips (optional):
During the Think-Pair-Share the teacher can display the number line models the students designed and allow them to explain the different ways they built their number lines.
The teacher can also allow students to write their own word problems with given parameters and allow students to exchange problems to solve.
Notes or Recommendations (optional):
If students do not have access to the digital tool, the teacher can provide paper copies of number lines and allow the students to build their own.
