Learning Targets (CCSS Aligned)

• Understand and represent integers on a number line.
  (CCSS.MATH.CONTENT.6.NS.C.5)
• Compare and order integers.
  (CCSS.MATH.CONTENT.6.NS.C.6)
• Understand absolute value and its meaning in real-world context.
  (CCSS.MATH.CONTENT.6.NS.C.7)

---

Success Criteria

• Students can correctly locate and plot positive and negative integers on a number line.
• Students explain the position of integers relative to zero and each other using proper vocabulary (greater than, less than).
• Students demonstrate understanding of absolute value by relating it to distance from zero.

Agenda

Time	Activity	Details
0-10 mins	Introduction & Warm-Up	Quick whole-class review of whole numbers; introduce integers via daily-life temperature/weather contexts.
10-25 mins	Interactive Number Line Exploration	Students use physical number lines (taped on floors or desks) where they jump or place cards representing integers to visualize positions and order.
25-35 mins	Guided Practice: Integer Ordering	Use mini whiteboards for students to write integers and arrange them from least to greatest and vice versa in pairs.
35-50 mins	Absolute Value Discovery	Through storytelling (e.g., how far a submarine is from the surface), students find the absolute value of different integers, using a number line.
50-60 mins	Independent Practice - Integer Positioning Worksheet	Worksheets with number lines missing integers; students fill in the blanks based on clues, including absolute value problems.
60-68 mins	Check for Understanding & Peer Sharing	Students explain their answers in small groups, encouraging reasoning and verbalization of integer concepts. Teacher circulates.
68-71 mins	Exit Ticket & Reflection	Quick written question on placing an integer on the number line or absolute value, plus one new thing learned.

Materials Needed

• Long taped number lines on the floor or desks (marked -10 to 10)
• Integer cards (number cards with positive and negative signs)
• Mini whiteboards and markers
• Integer Positioning Worksheets
• Exit tickets (index cards or strips of paper)

---

Differentiation & Engagement Notes

• For ESL or special needs students, offer integer cards with visual hints (e.g., thermometers, elevator floors).
• Use peer partners for collaborative practice to reinforce verbal skills.
• Physical activity (jumping on number line) addresses kinesthetic learners and helps keep attention for a large class.
• Incorporate storytelling for abstract concepts (absolute value) to make math relatable.

---

Assessment

• Formative: Monitor student participation during number line activity and mini whiteboard work.
• Summative: Completed worksheet and exit ticket responses.
• Use peer discussions to informally assess reasoning and language proficiency around integers.

Visual & Verbal Integration Tip:

Teacher Script Example During Number Line Activity:
"If you stand on -3, how many steps do you need to take to get back to zero? What does that tell us about the number -3?"

Encourage students to physically step and verbalize:
"It takes 3 steps to get to zero, so the absolute value of -3 is 3."

This multisensory approach cements the concept in memory!

Homework Recommendation

Assign a "Real-life Integer Hunt": Students list 5 examples of integers encountered outside school (e.g., temperatures, elevator levels, bank balances) and explain the integer’s meaning using absolute value language.

This highly interactive, Common Core-focused lesson blends movement, discussion, and practice geared to engage and accommodate a large class while meeting grade-level standards on integers.
