'Doubling each time' for 3rd grade
Number patterns: double the number each time
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.
- 2 ÷ 1 = 2
- 4 ÷ 2 = 2
- 8 ÷ 4 = 2
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:
- Confirm that the ratio between each pair of consecutive numbers is 2 by dividing them.
- Multiply the last number in the sequence by this ratio of 2.
- That gives you the next number in the sequence.
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 Mix and match 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.
In this game we are in a room with lots of toys - and the room needs clearing up - you need to put the play blocks back in the right boxes to tidy the room and win the game...but which is the right box for each block? Well, you can work that out by comparing the question on the block with the math answer on each of the boxes - you should drag the question block into the box whose math answer matches the picture question.
You can listen to the spoken math answer by clicking on the individual boxes. There are 5 blocks to clear up - but if you put them in the wrong boxes, there will be more... Anyway, tidy is good and practicing math is better so start now and see how you get on...
This game reinforces the math you learned or revised in the lesson by asking you to match each question to the correct answer. If you are older you may not like the childish reference to toys, but don't worry - there are other games to play, and who knows - you might like a trip down memory lane?

- Click on "PLAY" on the settings page to start the game
- You see the first question block and 3 boxes to put it into
- On each box is a possible math answer to the question
- Click on any answer box to hear the spoken audio for that answer
- Drag the question block to the answer box where it belongs
- If you are correct, the block will stay in the box, the ball will roll and the teddy bear will do a little jump
- If you are wrong, a wrong sound will play and the question block will jump back to where it was, and you can try again
- Clear all 5 question blocks to complete the game
