Worksheet Overview

QUESTION 1 of 10

Prepare to be a 2D shape builder!

 

Look at the shapes below:

 

 

In this question type, we need to join these two shapes together to make a new shape.

 

Matching letters have to touch, so, in this example, both the sides labelled a have to be touching each other.

 

Which of the following options would the new shape look like?

 

a)         b)         c) 

 

 

Did you choose option a?

If so, then you are correct!

 

The triangle lifts to go on top of the square.

Try and imagine the shapes moving together in your head.


 

 

Let’s try another one!

 

This time we have three shapes to join together.

Remember that matching letters must touch each other.

 

 

Here are the possible options:

 

a)         b)         c) 

 

The correct answer is c.

The triangle goes to the right of the rectangle, and the trapezium goes on top of the rectangle.


 

 

It’s now your turn to join shapes together.

 

Good luck 2D shape builder!

 

Hi there, 2D shape builder!

We're glad you're here to help us put the 2D shapes in this activity together in their correct positions. 

 

Look at these two shapes:

 

 

We need to join these two shapes together to make a new, combined shape. 

 

Sides with matching letters have to touch. 

This means that both the sides labelled a have to be touching each other. 

 

Once the shapes have been joined together, where will the triangle be? 

On the top

On the right

On the left

On the bottom

Now it's time to join our shapes from the last question together. 

 

Look at these two shapes again:

 

 

What will these shapes look like once they've been joined together? 

 

Remember that both the sides labelled a must be touching each other




Here's a new pair of sneaky 2D shapes to consider in this case:

Sides with matching letters have to touch. 

 

Once the shapes have been joined together, where will the rectangle be? 

Underneath the circular shape

Touching a straight edge of the circular shape

Touching a curved edge of the circular shape

Now it's time to join our shapes from the last question together.

  • Question 1

Hi there, 2D shape builder!

We're glad you're here to help us put the 2D shapes in this activity together in their correct positions. 

 

Look at these two shapes:

 

 

We need to join these two shapes together to make a new, combined shape. 

 

Sides with matching letters have to touch. 

This means that both the sides labelled a have to be touching each other. 

 

Once the shapes have been joined together, where will the triangle be? 

CORRECT ANSWER
On the top
EDDIE SAYS
How did you get on with this first challenge, 2D builder? The top side of the parallelogram (the slanted, rectangle shape) is labelled a , and so is the bottom side of the triangle. This means that these two sides need to be touching, so the triangle will sit on top of the parallelogram. The same letters always have to touch so don't be fooled by the sneaky letter b added in. This is a red herring designed to distract you, don't let it. Remember this important fact to help you track down the new shape in the next mystery...
  • Question 2

Now it's time to join our shapes from the last question together. 

 

Look at these two shapes again:

 

 

What will these shapes look like once they've been joined together? 

 

Remember that both the sides labelled a must be touching each other

CORRECT ANSWER
EDDIE SAYS
As we noted in the previous question, the triangle must be on the top so that the two sides labelled a are touching. This means that we can rule out option c straight away, as the triangle here is not on the top. Did you notice something strange about option a? The triangle used here is different, as it has a right angle, so it also cannot be correct. This makes option b the correct answer. Can you imagine the triangle moving to sit on top of the parallelogram?
  • Question 3

Here's a new pair of sneaky 2D shapes to consider in this case:

 

 

We need to join these two shapes together to make a new, combined shape. 

 

Sides with matching letters have to touch. 

 

Once the shapes have been joined together, where will the rectangle be? 

CORRECT ANSWER
Touching a straight edge of the circular shape
EDDIE SAYS
Can you imagine the rectangle moving to be on the top of the side labelled with a on the circular shape? This means it will join with a straight side of the curved shape. Keep this picture in your mind's eye to help you with the next challenge...
  • Question 4

Now it's time to join our shapes from the last question together. 

 

Consider these two shapes again:

 

 

What will these shapes look like once they've been joined together? 

 

Remember that both the sides labelled a must be touching each other

CORRECT ANSWER
EDDIE SAYS
Both of the sides labelled with an a need to be touching here. Can you imagine the rectangle flying across to sit flat on the straight, bottom edge of the circular shape? This would make our combined shape look like option a. Keep moving those shapes with your eyes - it's an awesome superpower to have!
  • Question 5

Look at these two new shapes:

 

 

We need to join these two shapes together to make a new, combined shape. 

 

Once the shapes have been joined together, where will the square be? 

CORRECT ANSWER
On the bottom
EDDIE SAYS
Both of the sides labelled with an a need to join here. Can you use your shape-moving powers to imagine the top edge of the square joining with the bottom edge of the arrow? This means that the square will be underneath the arrow. Keep your detective's eyes peeled to find out what these shapes will look like after they have been joined in our next challenge...
  • Question 6

Now it's time to join our shapes from the last question together. 

 

Think about these two shapes again:

 

 

What will these shapes look like once they've been joined together? 

CORRECT ANSWER
EDDIE SAYS
In the last question, we deduced that the square will be positioned below the arrow, which means that option c must be the correct answer. Keep up the excellent shape-joining work, detective!
  • Question 7

Look at these two new shapes:

 

 

We need to join these two shapes together to make a new, combined shape. 

 

Once the shapes have been joined together, where will the triangle be? 

CORRECT ANSWER
On the right
EDDIE SAYS
Here we have a triangle and a cross-shape to work with. We need to imagine joining both these shapes together, so that the sides labelled a are touching. Use your shape-moving powers to imagine the triangle moving to join the cross on its right-hand edge. Save a mental image of this in your mind to help you crack the next case...
  • Question 8

Now it's time to join our shapes from the last question together. 

 

Look at these two shapes again:

 

 

What will these shapes look like once they've been joined together?

CORRECT ANSWER
EDDIE SAYS
If the left-hand side of the triangle (labelled a) moves to the right-hand side of the cross, this would look like option b. Can you visualise the shapes moving in your head? It's time to feast your eyes on our final pair of shapes now.
  • Question 9

Look at these two final shapes:

 

 

We need to join these two shapes together to make a new, combined shape. 

 

Once the shapes have been joined together, where will the triangle be? 

CORRECT ANSWER
To the right of the L-shape
EDDIE SAYS
Can you see the two sides we need to join here? The left-hand side of the triangle, needs to join with the upper, right edge of the L-shape. Can you imagine what this will look like in your head? Take a mental photo of this and save it to use in your final mission...
  • Question 10

Now it's time to join our shapes from the last question together. 

 

Look at these two shapes again:

 

 

What will these shapes look like once they've been joined together? 

CORRECT ANSWER
EDDIE SAYS
Did you spot the correct option here? If the triangle flies over to join the upper, right side of the L-shape, this would look like option b. Great work on all your excellent shape-joining skills in this activity! You can now imagine moving regular and irregular shapes to join sides with matching letters, ignoring other letters which have been added as a distraction - fantastic focus!
