We call such numbers ‘even numbers’. Shirley’s numbers are called ‘odd numbers’. Identify numbers between 1 and 20 as even or odd. You may draw the pairing arrangement of the numbers. Odd Even Note for Teachers: Encourage students to identify the pattern-number of objects that can be paired (even) and those that cannot be paired (odd). Do you think all numbers in the times-2 table are even?

Shiv wonders if both the numbers, before and after an even number, will be odd. What do you think? Check and discuss. Choose any 10 numbers in order without skipping any (consecutive numbers). Write whether they are even or odd below each number. What do you notice? Discuss. Identify which of the following numbers are even and which are odd. Explain your reasoning.
