Comparing Numbers Using Symbols

Comparing Numbers Using Symbols

Year 7-8 Mathematics Learning to use >, <, and = symbols 45-minute lesson

WALT (We Are Learning To)

Use comparison symbols (>, <, =) to compare numbers Compare sums and differences accurately Explain our reasoning using mathematical language Use materials like number lines and counters to help us

Success Criteria

I can accurately use >, <, and = to compare 5 different mathematical expressions I can use number lines and counters to support my understanding I can explain why one number is greater, less than, or equal to another Challenge: I can create my own number comparison statements

The Three Comparison Symbols

Number Line Practice

Use the number line to compare these pairs: 5 + 2 ___ 9 - 1 3 + 4 ___ 2 + 5 8 - 3 ___ 6 - 2 Work with a partner and use counters if needed

Differentiation Strategies

{"left":"Support: Use number lines and counters for every problem\nSupport: Complete sentence starters like 'This is greater because...'\nSupport: Work with a buddy for extra help","right":"Challenge: Create your own comparison problems\nChallenge: Try comparing expressions with larger numbers\nChallenge: Explain your thinking to others"}

Think-Pair-Share

Look at this comparison: 6 + 4 ___ 12 - 2 First, solve each side on your own Then, discuss with your partner which symbol goes in the blank Be ready to explain your reasoning to the class

Lesson Summary & Next Steps

Today we learned to use >, <, and = symbols correctly We practiced comparing sums and differences We used number lines and counters to help our understanding Next lesson: We'll compare larger numbers and simple algebraic expressions Remember: It's okay to use materials to help you think!
