The document discusses building structures in Minecraft and calculating perimeters. It explains that to build in Minecraft or in real life, you must first define the space by knowing the distance around it, which is the perimeter. It provides examples of how perimeter is used to determine materials needed for structures like houses, fences, and football pitches. It poses questions about calculating perimeters of different shapes and deciding which structures have larger perimeters.

2. Sam, My best
friend really loves
playing Minecraft
because he can
build amazing
buildings in it.
Look at the shape
he just made to
define the space he
will use to build in.
Could you figure
out how many
blocks he used?

3. Look at the new
shape he made.
How many blocks
did he use? What
kind of construction
will he make using
this shape? Let’s
imagine some cool
projects…A pool?
A house?

4. Building a house in real life implies defining the space that
architects, engineers and builders will use to work on. That is
why, professionals use measuring tools to know the distance
around the zone under construction. This is known as the
perimeter of the zone.

5. Let’s see some examples…
To build a house like the one below workers need to know the
length around of each zone to define the amount of materials
they will need to do this beautiful work.

6. We need to know about perimeter to figure
out how many wooden posts we will use to
make a fence for our dog house.
Builders need to know about
perimeter to build up a football
pitch to play on.
Farmers needs to know about
perimeter to build up a fence
to protect their harvests.

7. Let’s find perimeters…
To find the perimeter we must add up all the figure sides.
Directions: Find the perimeter of the following figures.

8. Critical thinking
Directions: Find the perimeter of the following figures.
How could you figure out what are the values of the missing sides?

9. Directions: Solve the following problems.
If you were going to build a house in Minecraft, what might the
perimeter equal? What would be a reasonable number of blocks?

10. Sam started to build 2 houses in Minecraft. He wants to build
the house with the largest perimeter. Which house should he
continue to build? Why?

11. This time Sam is building 2 barns. Help him to decide
which barn could store the most inside. Explain why.

12. Critical thinking:
This shape has
congruent sides which
means that they are equal
length sides. So, the
perimeter of this figure is
a repeated addition:
5+5+5+5.
Could we find the
perimeter of congruent
sides figures using a
different operation from
adding?
