In this lesson, we’ll introduce the concept of negative numbers to `6`th graders. Students will get to do an exploratory activity where they become a number line! Students will work together through number sense to place their numbers `-6` through `6` to create a human number line. They will get to play a game of simon says as well to understand absolute value.
ByteLearn gives students targeted feedback and hints based on their specific mistakes
Students will be able to plot negative numbers on a number line and understand the absolute value of a number.
Start the lesson off by displaying slide one of the teacher slideshow.

Give students a few minutes to think about where they would place `3, -3, 4,` and `-4` on the number line. Once they are done, have a few students share where each number would go and why.
Explain to students that all positive numbers will go to the right of the `0` and all negative numbers will go to the left of the `0`.
Transition to the following slide `(3)` to ask a few extended questions.
Ask students what the distance is from `1` and `0` as well as `-1` and `0`. You can also then ask students what is the distance from `-3` and `0` and `3` and `0`. We want students to see that there is the same distance between both. Tell students that this is known as the absolute value because distance is always positive.
Explain to students what the opposite of a number means as well. Go through these examples with the students. Display slide `4`.
Tell students that they are going to create a human number line! Print out the `-6` through `6` digits and hand a number out to `13` students. Have those students arrange themselves. This activity is great because it gets students moving and they get to talk to each other about the order and what makes sense.
Once students have correctly placed themselves in order we can play some rounds of simon says! Now the audience will get to play! Give `1` or two examples and then have students in the audience ask their human number line. Simon says questions.
We are going to play this game twice. Now it’s time for the audience to become the number line.
Once students have completed, collect the cards and shuffle them so that the audience and the students in the number line can switch roles.
After you’ve completed the examples with the whole class, it’s time for some independent practice! ByteLearn gives you access to tons of introduction to negative numbers activities. Check out the online practice and assign to your students for classwork and/or homework!
