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 a number pattern where the next number is worked out by doubling the current one (multiply it by 2). This doubling pattern is easiest to understand by looking at examples. Let's start by looking at the simplest example:
1 , 2 , 4 , 8 , _ , _ ...
What comes next? To find out, let's first make sure this pattern is a doubling pattern by looking at the differences between each pair of numbers. You may notice that we are using multiply and divide because this pattern is a geometric sequence, not an arithmetic sequence.
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
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 size of the number each time:
This topic asks you to work out the missing number in the pattern of numbers created by doubling the current number each time.
With our Four in a row math game you will be practicing the topic "Doubling each time" from 3rd grade / Pattern / Number patterns. The math in this game consists of 16 questions that ask you to pick the next 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.
