Note to Parents:
Identifying even and odd numbers is an important Math skill that will prepare children to learn division and prime numbers. Instead of merely getting children to memorize that 0, 2, 4, 6 and 8 are even and 1, 3, 5, 7 and 9 are odd numbers, this week’s lesson explains the concept of even and odd using the story, “Seven Jelly Beans” where two friends were trying to divide 7 jellybeans equally
among themselves. They find that they are not able to do so

C
because, 7 is an odd number. When, they started to fight, Owl
came along and ate one jellybean. With 6, an even number, the
friends were able to divide the jellybeans equally among
themselves and their problem was solved!
Concept
Even numbers can be divided evenly into groups of two.
Odd numbers cannot be divided evenly into groups of two.
In subsequent levels, our students will be exposed to problems that
require the use of even and odd concepts to solve.
*Example : Primary 2
What is the colour of the 99th bead?
*Example : Primary 3 (P1 HOT Q2 builds basic concept fr this qn)
Is the result of 1 + 2+ 3 + ….. + 20 odd or even?
*modified MOE Gifted Education (GEP) screening exam.
