- Estimation of outcome of number operations.
- Introduction to a sense of the largeness of, and initial familiarity with, large numbers up to 8 digits and approximation of large numbers.
- Numbers in Indian and International Systems and their comparison.
Natural numbers and Whole numbers
- Natural numbers.

- Revision of what a fraction is.
- Fraction as a part of whole.
- Representation of fractions (pictorially and on number line).
- Fraction as a division.

Playing with Numbers
- Simplification of brackets.
- Multiples and factors.
- Divisibility rule of 2, 3, 4, 5, 6, 8, 9, 10, 11. (All these through observing patterns. Children would be helped in deducing some and then asked to derive some that are a combination of the basic patterns of divisibility)
- Even/odd and prime/composite numbers, Co-prime numbers, prime factorisation, every number can be written as products of prime factors.
- HCF and LCM, prime factorization and division method for HCF and LCM, the property LCM × HCF = product of two numbers.
Theme 2: Ratio and Proportion
- Difference between fraction and ratio.
- Concept of Ratio.
- Proportion as equality of two ratios.

- Word problems on ratio and proportions.
- Idea of percent as fraction with 100 as denominator.
- Idea of speed and simple daily life problems related to speed, time and distance.
Theme 3: Algebra
- Introduction to constants, variable and unknown through patterns and through appropriate word problems and generalisations (For example 1+3=22, 1+3+5=32, 1+3+5+7=42 , sum of first n odd numbers = n2.).
- Generate such patterns with more examples and generalisation.
- Introduction to unknowns through examples with simple contexts (single operations)
- Terminology associated with algebra - like literal numbers, terms, expressions, factor, coefficient, polynomials, degree, like and unlike terms.
- Framing algebraic expressions.
