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. All this is to be embedded
in contexts that bring out the
significance and provide motivation
to the child for learning these ideas
