Lesson 2: Comparing Numbers
Aims:
- Teach children to compare written numbers and their values.
- Use visual models to reinforce understanding of bigger and smaller numbers.
Goals:
- Children identify which number is bigger or smaller.
- Children use visual models and quantities to make comparisons.
Objectives:
- Given two numerals, state which is bigger or smaller.
- Use manipulatives or pictures to represent and compare numbers.
Transformation:
- Move from comparing actual objects to comparing abstract numbers and symbols.
Foundation:
- Familiarity with numbers up to 10 and comparative language.
What Happens Next:
- Sets the stage for ordering numbers and simple operations (adding, subtracting).
Skill Progression:
- Number comparison
- Visual modeling
- Symbolic thinking
Sample Activities:
- Number Showdown: Show two number cards; ask which is bigger or smaller.
- Build and Compare: Make groups with cubes or counters to match each number, then compare.
- Visual Models: Use ten frames or dot cards to represent and compare numbers.
Assessment:
- Check if children correctly identify bigger/smaller numbers and use models effectively.
Materials:
- Number cards (1–10)
- Cubes, counters, or dot cards
- Ten frames
Differentiation:
- Use tactile or large-print cards for accessibility.
- Allow children to draw or build their own models as needed.
Integration:
Compare numbers in daily routines (calendar, lining up, counting items).
