a ten, or making a decade

relationships

from one shape to the next
– draw up a table of values

7. Lesson 2
• There are other
insects on the planet
Elsinore. They look
as if they have been
made up from
squares. The ones
with one foot are
called 1-pedes. The
ones with two feet
are called 2-pedes
and the ones with 3
feet are called 3-
pedes.
8. Lesson 2
• Did you know that ‘pede’
means ‘foot’?
Hint: write the

• What did you find
out about the
Spotted Pedes?
• What patterns did
you find?
• Make sure your
answers are in the
same powerpoint.

18. Lesson 4
• Here we are going to
explore the Big-Headed
Pedes. This is what they
look like.
• How many yellow
squares does a Big-
Headed Pede 4-pede
have?
How many yellow
squares does a Big-
Headed Pede 5-pede
have?
How many yellow
squares does a Big-
Headed Pede 6-pede
have?
Do you need to draw the insects to work out how many squares they have? Why or why
not?
Could you work out how many yellow squares a Big-Headed Pede 10-pede would have?
19. Lesson 4
• What did you find out
about the Big-Headed
Pedes?
• What patterns did you
find? Think about the
squares that make up
the feet, and the
squares that do NOT.
Feet
I saw a Big-Headed Pede with 16 yellow squares. How many feet did she have?
