KSP Математика 6 grade: Сравнение десятичных дробей

This Grade 6 Mathematics lesson plan on “Comparing Decimal Fractions” helps teachers teach students to determine which decimal fraction is greater, smaller, or equal, developing calculation skills and logical thinking.

Lesson objective: to teach students to compare decimal fractions and apply this skill in practical problems.

Expected outcomes:

students determine the order of decimals;
compare decimals with different numbers of digits after the decimal point;
use the signs «>», «<», «=»;
apply comparison in problem-solving.

Lesson structure:

Organization
Greeting.
Prior knowledge
Review decimals and writing decimals with different numbers of digits.
New topic
Compare whole parts first
If whole parts are equal, compare fractional parts digit by digit
Examples:
2.45 > 2.4
3.05 < 3.1
Use signs «>», «<», «=»
Practice
Compare 0.75 and 0.8
Compare 1.2 and 1.19
Arrange 2.3; 2.33; 2.31 in order
Practical problem: two containers with 3.25 L and 3.2 L. Which is larger?
Consolidation
Pair work: check solutions and discuss mistakes.
Reflection
Discuss practical applications of comparing decimals.
Conclusion
Summary, brief feedback, mention assessment (5–10% of text).

Teaching methods: explanation, practical work, pair work, discussion of examples.

How to compare decimal fractions?
Compare whole parts first, then fractional parts digit by digit.

What if the number of decimal places is different?
Add zeros to equalize the number of digits, then compare.

Which signs are used?
«>», «<», «=».

Why compare decimals?
To determine the correct order of numbers, calculations, and practical problem-solving.

Can comparison be applied in real life?
Yes, in measurements, money, volumes, and lengths.
