Welcome to the tutorial for Fixation Numbers.


Numbers are flashed on the screen one after another. The student inputs a number on a keypad based upon the instructions. Lower levels just input certain numbers seen. Higher levels require the student to remember a previous number and do simple math to arrive at the final answer.


Skills trained:

Major: sustained attention, selective attention, divided attention, saccadic fixations, math computations

Minor: working memory, processing speed, logic and reasoning, VP-discrimination, sensory-motor integration


When you first click to begin any exercise, you will see the instruction screen. These instructions change for each level. There is a link to play an audio version of the instructions if needed.


Otherwise click OK to go to the next screen. On the next screen, click start to begin the exercise.


Below are the instructions for level 1.



A series of numbers will be displayed on the screen in random locations. Some numbers will be circled, some will not be circled.


When you see a circled number, enter that value as quickly as you can using the screen keypad or the keyboard.


Ignore the numbers that are not circled.


Below is an example of a circled number that you need to enter.



The numbers may appear any where on the open screen. This helps to train the ability of the eyes to scan and focus quickly.

Each higher level will be more complex. Below are the instructions for each level.


Level 1
Enter the circle numbers.


Level 2
Enter each red number.


Level 3
Enter the number you see right after a red number. Students will have to enter that number while simultaneously paying attention to the next number after each red number.

  • A series of numbers will appear on the screen.
  • Assume the following sequence appears: 2, 5, 1, 7, 8, 6, 5, 2, 4, 3, 9
  • You cannot enter anything with the first number. Just note it. It is not red, so ignore it.
  • The next number is a red 5. Take note. The instructions say to enter the next number that appears after a red number. So you will enter the next number regardless of its color.
  • The next number is 1. Enter 1 because it is the next number right after a red number.
  • Also check the 1 to see if it is red. It is not, so ignore it.
  • Check the next number. It is not red, so ignore it.
  • Check the next number. It is a red 8, so take note. Enter the next number you see because it is after a red number.
  • The next number after the red 8 is 6, so enter 6.
  • Note that the 6 is red, so you will enter the next number.
  • The next number is 5, so enter the 5. The 5 is not red, so you will not enter the number after it.


Level 4
Enter the number you see right after a target number. Target number will be defined randomly for each round.


Level 5

Enter the number you see that comes before a red number. Student will have to remember each number then quickly check the next number to see if it is red. If it is red, the student must enter the previous number and remember the current red number, because it may also be used as the next number can also be red.


For example, if you see the following sequence, 2, 3, 5, 2, 1, 6:


On the first 2, do not enter anything. It is not before a red number.

On the 3, do not enter anything yet, but remember it.

When you see the red 5, enter 3, which is the number before a red number.
Now also remember the 5.

When you see the red 2, enter 5, because it was the number before a red number.


Level 6
Enter the number you see that comes before the target number. Target number will be defined randomly for each round.


Level 7
Enter the number that comes right after a red number, but add 1 to it for your answer.


Level 8
Enter the number that comes right after a target number, but add 2 to it for your answer.


Level 9
Enter the number that comes right before a target number, but add 3 to it for your answer. If 3 came before the target number, add 3 which equals 6 and enter 6 as your answer.


Level 10
Enter the number that comes right before a target number, but add 4 to it for your answer. If 2 came before the target number, add 4 which equals 6 and enter 6 as your answer.


Level 11
Use the number that comes before a red number, take that number and enter the net difference between that number and 5. If 2 came before a red number, compare 2 to 5, the net difference is 3, enter 3 as your answer.


Take the following sequence: 2, 7, 5, 4, 6, 1, 3, 5


Remember the 2 and wait to see if the next number is red.

The next number is 7, but it is not red. Forget the 2 and remember the 7.

Look to see if the next number is red. It is. So take the difference between 7 ( the previous number before a red number) and 5, which is 2. Enter 2 before the next number appears.

Forget that 5 was red now. Just treat it like any other number. Remember the 5 to check and see if the next number is red.
It is. So take the difference between 5 and 5 and enter 0.

Now forget that the 4 was red. Treat it like the next number and remember it to see if the next number is red.

It is not, forget the 4 and remember the 6 to see if the next number is red.

It is. Take the difference between 6 and 5 and enter 1.


Having multiple red numbers in a row does not matter. Red numbers count for comparison to see if the next number is red.


We don’t use negative numbers. So if the number is 1 and you take 5 away, don’t enter -4. Just enter the absolute value of 4, the difference.


Level 12
Use the number that comes before the defined target number, take that number and enter the net difference between that number and 9. If 2 came before a target number, compare 2 to 9, the net difference is 7, enter 7 as your answer.


Level 13
Use the number that comes just before a target number and just after a target number. Compare the two numbers and enter the net difference. For example, if 5 is the target number and you see the following sequence on the screen, 3-5-1-4, the number 3 is before the target number of 5 and 1 is after. The net difference between 3 and 1 is 2. Enter 2 as your answer.

Remember, the red or target number can occur in sequence and be used as one of the numbers in the calculation. For example, if you are to enter the number before a red number and a non-red number comes up, then two red numbers in a row, the 2nd red number will also have to be entered as an answer.
