Remember: Look for the pattern in a row or across the table. A pattern can tell you when an answer looks wrong.

Patterns in a row

1
The 4 times row. What goes in the box?
2

3
Which is true about the 5 times row?

Patterns in the table
120 Each answer is 4 more than the one before. 16 + 4 = 20.
236 Each answer is 6 more. 30 + 6 = 36.
3Every answer ends in 5 or 0 5, 10, 15, 20, 25, 30 all end in 5 or 0. Each answer is 5 more, and 10 is not odd.
4Each answer is 2 more than the one before 2, 4, 6, 8, 10, 12 goes up by 2 each time.
5The answers go odd, even, odd, even 9 is odd, 18 is even, 27 is odd, 36 is even. They switch every time.
64 9 is 1 less than 10, so 9 × 4 is 4 less than 10 × 4. 40 - 4 = 36.
715 3 × 5 and 5 × 3 are the same, and row 5, column 3 is 15.
8Row 5, column 4 4 × 5 and 5 × 4 are the same, so swap the row and the column.
9True Turn 3 rows of 5 and you get 5 rows of 3, so row 3 column 5 and row 5 column 3 are both 15.
10False 3 groups of 7 and 7 groups of 3 are the same boxes turned round, so both are 21.
116 Swap the two numbers and the answer stays the same.
122 7 is 5 and 2 more, so 6 × 7 is 6 × 5 plus 6 × 2: 30 + 12 = 42.
131-A, 2-B, 3-C, 4-D
