Understanding the 8 Times Table

  • Each number in the 8 times table is double the number in the 4 times table, which in turn is double the number in the 2 times table. This means a lot of doubling involved in this sequence!
  • Here is the 8 times table. Pay close attention to the tens column and the ones column.

  • Patterns in the Ones Column: The ones column in the 8 times table decreases in twos, starting from 8 and then cycling through 8, 6, 4, 2, 0 repeatedly.
    • Example: 8 x 1 = 08, 8 x 2 = 16, 8 x 3 = 24, and so on, showing the pattern as 8, 6, 4, 2, 0, 8, 6, 4, 2, 0.
  • Patterns in the Tens Column: The tens column in the 8 times table increases by 1 each time, but when it reaches 4 and 8, it repeats the number before incrementing.
    • Example: 8 x 1 = 08, 8 x 2 = 16, 8 x 3 = 24, and so on, demonstrating the pattern as 1, 2, 3, 4, 4, 5, 6, 7, 8, 8, 9.

Examples

Example 1: There are 11 octopuses swimming near the shore. How many legs are there altogether?
The 8 times table | Year 4 MathematicsSol: We know that octopuses have 8 legs, so we need to calculate 11 x 8.
According to the 8 times table:
8 x 11 = 88
Therefore, there are 88 legs in total.

Example 2: What does this array represent?
Sol: 
It represents a multiplication in the 8 times table. Count the top row and the left-hand column to find out which one.

Count the apples along the top row. There are 8.
Now count the apples in the left-hand column. There are 5.
There are 8 lots of 5 (or 5 lots of 8). You can write this as 8 x 5 or 5 x 8.
8 x 5 = 40
