Phase:  During/Explore/Explain 
Activity:  Begin by reviewing the number zero, and how integers are less than zero. Have students give examples of a situation that can be described with a positive or negative value (ex. giving away money, swimming up through the water, driving back to get something you forgot). Give each student four index cards. They should listen carefully and place a different value on each card:
After the students have written their four numbers, have them put them in order from smallest to largest on their desks. Check for accuracy. Next, have the students combine cards with a partner and put them in order from largest to smallest. Check for accuracy. Next, students in each group should combine and order cards (1620 numbers). This one can be a competition, whoever finishes first gets bragging rights. Finally, have all of the kids put the cards back in random order facing down in the middle of the group. Each student should pick one card without looking at it or showing other students. When the teacher says go, the object of the last activity is to order the students in the class from smallest to largest. Each student places their integer card on their forehead, and they can’t look at it. The students have to stay silent the entire time. They must arrange each other in order without knowing what their own number is. After everyone has been arranged, check for accuracy. Choose a few students at random to leave the line and pick a new number card from the desks. They now have to figure out how to place themselves back in the line. Continue until all students have been moved around. In order to leave the line and go sit at their seat, students have to come up with a situation that describes their integer card. In closing, ask questions such as:

Assessment Strategies:  Students can show FisttoFive at the beginning and end of the lesson as an informal pre and postassessment. (They hold up fingers to show their understanding, a fist means they didn't understand at all, one finger means they understood a little, all five fingers means they understand it perfectly and could teach it to a friend.) Observation during the practice will show which students need further support. The exit ticket (Ordering Integers Exit Ticket) shows whether students can compare and order integers. 
Advanced Preparation:  Gather enough index cards for each student. Copy exit tickets for the students (there are four on a page).
