The pattern behind the list
Every answer in the 10 times table ends in 0, so the list is easy to check: the answers are the 1 times table with a zero on the end.
Working out big facts
You do not need to learn all 25 facts by heart. Use the method for the 10 times table instead: To multiply a whole number by 10, write a zero on the end.
25 tens are 250. The digits slide one place to the left and a zero fills the gap.
10 × 25 = 250
