Question 1
Which number is even?
Correct answer: C
14 can be split into two equal groups of 7, and its ones digit 4 is even. The numbers 7, 15 and 21 end in odd digits.

Question 3
Jin puts 7 counters into pairs. How many counters are left without a partner?
Correct answer: B
7 counters make 3 pairs, which use 6 counters, and 1 is left over. That is why 7 is odd.
-
Question 4
Which doubles fact shows that 16 is even?
Correct answer: D
An even number is the sum of two equal addends, and 8 + 8 uses the same number twice. The other facts are true but do not use equal addends.

There are 18 students in a class. Can every student have a partner, with nobody left out?

18 = 9 + 9, so the students make 9 pairs with no one left. A number that pairs up exactly is even.

The numbers 2, 10, 24 and 36 all end in 0, 2, 4, 6 or 8. The other lists include 9, 15 or only odd numbers.

Question 7
A number is even when its ones digit is which of these?
Correct answer: D
Every even number ends in 0, 2, 4, 6 or 8, like 30 or 56. Numbers ending in 1, 3, 5, 7 or 9 are odd.
-
Question 8
An array has 2 rows with 6 stars in each row. How many stars are there, and is the number even or odd?

6 + 6 = 12 stars. Two equal rows always make an even number, so 12 is even.
-

Correct answer: A
Odd numbers go up by 2: 23, 25, 27. The number 24 comes next, but it is even.
