# Find the Missing Symbol to Complete the Grid

In this worksheet, students will find the missing symbol to complete a grid of four boxes. It will develop their ability to find and follow patterns in shapes and symbols.

Key stage:  KS 2

### QUESTION 1 of 10

It’s time to be a puzzle perfecter!

In these questions, we have been given a grid and we need to work out the missing puzzle piece.

Grids can follow a pattern which goes across.

To find the missing puzzle piece, we first need to think about what the pattern might be.

Here are some example patterns and how they change in the grid:

 Pattern Example Grid Shading gets lighter or darker. Size of shapes gets bigger/smaller. The shape turns.

Take a look at this example:

Which of the following images would complete the missing box in the grid?

a)         b)         c)

The pattern in this case is that the shapes get slightly smaller each time.

So the answer must be option b!

It’s now your turn to find the missing puzzle piece in grids.

Remember to work out what the pattern is in the top two squares, before applying it to the bottom two squares.

Good luck puzzle champ!

In the following questions, you are going to learn how to complete grids by spotting the connections between the shapes.

Let's put all your learning into practice now.

It's your turn to be the teacher.

A student has completed the grid below by drawing in the missing shape in the bottom right-hand corner.

Is the student correct or incorrect?

Correct

Incorrect

Select all the statements below that identify why the shape in the bottom left-hand corner doesn't fit with the others well.

Too many sides

Too small

Wrong colour

Wrong outline

• Question 1

In the following questions, you are going to learn how to complete grids by spotting the connections between the shapes.

Which of the following shapes do you think will best complete the grid below?

EDDIE SAYS
Welcome to the grid shape sorter! When we compare the shapes already in our grid, we can see that they are all the same size and that they all have 8 sides. The shape in the top right-hand corner has a darker or thicker outline than the others, which is important. We can assume that the missing shape will also have a darker or thicker outline as it is also on the right-hand side. Did you know that an 8-sided shape is called an octagon? Move to the next question to learn more about WHY this is the best answer and how we can justify our answer, as a top detective needs to be able to do.
• Question 2

Choose the correct explanation from the list below to explain WHY option a and option b are incorrect.

a)         b)

EDDIE SAYS
Option a does not work as it is a rectangle, not an 8-sided shape. Option b is the same 8-sided shape and it has a thicker outline, but it has been rotated (turned around). As none of the other shapes have been turned, we can assume this is not correct. We can say that this option has the wrong orientation. This leaves us with option c, which is the same 8-sided shape, with a thick outline but is sitting on a different edge to the other shapes in the grid. Phew! Well done if you spotted the first one. Imagine or practise explaining how you reached your answer to a friend or adult so that you can explain the detective steps you took.
• Question 3

Which of the following shapes do you think will best complete the grid below?

EDDIE SAYS
• Question 4

Choose the correct explanation from the list below to explain WHY option a and option c are incorrect.

a)        c)

EDDIE SAYS
Option a is the same shape and it is the right colour, but it is too small to match the pattern of increasing in size between the top and bottom rows. Option c is the right shape and has the right size, but it has the wrong shading to fit with the pattern of the right-hand shapes being shaded in grey. This leaves us with option b from the previous question. This is the same shape, has the same shading and is the correct size to complete the pattern. So far we can add these things to our detective notebook to look out for: colour/shading, shape, size, line thickness and orientation. Let's move on to see what else we can discover!
• Question 5

Which of the following shapes do you think will best complete the grid below?

EDDIE SAYS
What can we see here? When we compare the shapes already in this grid, we can see that the shapes on the left are the same colour and size. On the top row we have diamonds and on the bottom row a circle. On the right-hand side we have a larger diamond. We would expect a larger circle to be in the missing corner of the grid, so option a is our best fit. Move to the next question to learn more about WHY this is the best answer and how we can justify our answer, as a top detective needs to be able to do.
• Question 6

Choose the correct explanation from the list below to explain WHY option b and option c are incorrect.

b)         c)

EDDIE SAYS
Option b is the wrong shape as we need to find a circle to sit in the bottom row of our grid. Option c is the right shape, but it is the wrong size to fit with the pattern of the shapes on the right-hand side being larger. This leaves us with option a, which is the correct shape and size to complete the pattern. Great work so far shape detective!
• Question 7

Which of the following shapes do you think will best complete the grid below?

EDDIE SAYS
When we compare the shapes already in this grid, we can see that we have a grid of triangles of the same size and colour. On the left-hand side, they are both pointing upwards but they have different outlines (one solid and one dashed). On the right, the triangle has been rotated so that it is pointing right. We would expect to see a triangle pointing right in the bottom corner with a dashed outline, so option b is the best fit. Move to the next question to learn more about WHY this is the best answer and how we can justify our answer, as a top detective needs to be able to do.
• Question 8

Choose the correct explanation from the list below to explain WHY option a and option c are incorrect.

a)         c)

EDDIE SAYS
Option a has the right outline but is pointing in the wrong direction to fit the pattern of pointing right in the right-hand column. Option c is pointing in the correct direction but has the wrong outline to match the pattern of having a dashed outline in the bottom row of the grid. This leaves us with option b, which is the correct orientation and has the correct outline. Only two questions to go to be grid-tastic!
• Question 9

Let's put all your learning into practice now.

It's your turn to be the teacher.

A student has completed the grid below by drawing in the missing shape in the bottom right-hand corner.

Is the student correct or incorrect?

Incorrect
EDDIE SAYS
Did you use your detective's eyes to spot that this was a mistake? Let's move on to the next question to identify what the student did wrong.
• Question 10

Select all the statements below that identify why the shape in the bottom left-hand corner doesn't fit with the others well.

Too small
Wrong colour
EDDIE SAYS
In order to fit with the pattern here, the student should have drawn a shape that is white to match the shape in the square above. Also, it should have been larger in size to match the shape in the square on its left-hand side. Fantastic work puzzle detective! You have now completed this activity.
