Game: FOUR IN A ROW
Aim: To get four symbols in a row
Method:
Choose a square and click on it. Click on the correct answer to the question in the box that appears. If you are right the square is replaced by a tick. Continue until you have won 4 in a row...
This topic focuses on number patterns where each subsequent number is obtained by doubling the previous one. These patterns, known as geometric sequences with a common ratio of 2, are easiest to understand by looking at examples. Let's start by looking at one such number pattern:
1 , 2 , 4 , 8 , _ , _ ...
What comes next? To find out, let's first look at the differences between each pair of consecutive numbers:
You can see that in each step, we multiply the previous number by 2 to get the next number in the sequence. That is because doubling a number is the same as multiplying it by 2. Now, let's use this rule to find the next number:
8 x 2 = 16
So, the next number in the pattern is 16. The sequence now looks like this:
1 , 2 , 4 , 8 , 16 , _ ...
If we do the next number in the sequence, it will be 16 x 2 which is 32,
1 , 2 , 4 , 8 , 16 , 32 ...
To recap, always remember the following steps when identifying the next number in a pattern that doubles the number each time:
This topic asks you to work out the next number in the pattern of numbers created by doubling the number each time.
With our Four in a row math game you will be practicing the topic "Doubling each time" from 4th grade / Pattern / Next number. The math in this game consists of 21 questions that ask you to pick the missing number in these number doubling patterns.
The game will reinforce the math you have chosen to learn by getting you to match the question to the correct answer.
