Operations with Integers

Purpose: Activate prior knowledge and introduce the learning goal

Activities:

• Welcome and attendance (2 minutes)
• Warm-up problem or mental math exercise related to operations with integers (5 minutes)
• Share and discuss the learning goal and success criteria with students (3 minutes)
• Connect to previous learning and real-world contexts (5 minutes)

Teacher Prompts:

• "What do you already know about operations with integers?"
• "Where have you seen operations with integers in your everyday life?"
• "What questions do you have about today's topic?"
• "How might this connect to what we learned last week?"

Real-World Connection:

Financial transactions, temperature changes over time, sports statistics (gains and losses), elevator movements, and sea level measurements.

Assessment for Learning:

• Observe student responses during warm-up to gauge prior knowledge
• Use diagnostic questions to identify misconceptions
• Note students who may need additional support or extension

Materials Needed:

• Whiteboard and markers
• Chart paper for recording learning goals
• Visual aids or manipulatives for demonstration

Purpose: Students actively explore and develop understanding through hands-on activities

Main Activity: Partner work on word problems that require integer operations

Instructional Approach:

• Introduce the main activity and provide clear instructions (5 minutes)
• Model the activity or provide a worked example (5 minutes)
• Students work in pairs or small groups on the activity (25 minutes)
• Teacher circulates, observes, asks probing questions, and provides support (ongoing)
• Students share strategies and solutions with the class (10 minutes)

Differentiation Strategies:

• Provide manipulatives and visual aids for students who need concrete representations
• Offer extension problems for students who finish early or need additional challenge
• Provide sentence frames and vocabulary support for English Language Learners
• Allow students to work at their own pace with scaffolded support as needed
• Use flexible groupings based on readiness and learning needs

Teacher Prompts and Guiding Questions:

• "What strategy are you using to solve this problem?"
• "Can you explain your thinking to your partner?"
• "How does this representation help you understand the concept?"
• "What patterns do you notice?"
• "Can you think of another way to solve this problem?"
• "How can you check if your answer is reasonable?"

Mathematical Discourse:

• Encourage students to share multiple solution strategies
• Facilitate discussions about the efficiency and accuracy of different approaches
• Ask students to justify their reasoning and provide evidence
• Promote respectful listening and building on others' ideas

Assessment as Learning:

• Students self-assess their understanding using success criteria
• Peer feedback during group work and sharing
• Students reflect on their problem-solving strategies

Materials Needed:

• Integer chips or two-color counters
• Number lines
• Word problem cards
• Calculators
• Whiteboard and markers
• Partner work handouts

Purpose: Synthesize learning and assess understanding

Activities:

• Class discussion: Share key insights and strategies (7 minutes)
• Summary of main concepts and big ideas (3 minutes)
• Exit card or quick assessment (3 minutes)
• Preview of next lesson and homework assignment (2 minutes)

Consolidation Questions:

• "What did you learn today about operations with integers?"
• "What strategy was most helpful for you?"
• "How can you apply what you learned today to other situations?"
• "What questions do you still have?"
• "How does today's learning connect to our previous lessons?"

Exit Card Prompt:

Solve: (-4) + 7 = ? and (-3) × 5 = ? Explain your strategy for one of these problems.

Assessment of Learning:

• Review exit cards to assess student understanding
• Identify students who need additional support or intervention
• Use results to inform planning for the next lesson

Connection to Future Learning:

• Preview how this week's topic connects to next week's lesson
• Assign homework that reinforces today's learning
• Encourage students to look for examples of operations with integers in their daily lives
