1. DO NOW
1. Copy the objective on page 8L.
2. Complete the following on your index card:
Write in your own words, a description
of where in the room your seat is.
Do not draw, use only words.
Do not include any people in your
description, because it should work no
matter who is in the room.

2. Turn your cards in to the
teacher.

5. How can we tell if an object is in
motion?
• First we have to describe its position!
• Position – an object’s place or
location

7. When you get your new card:
1. Silently read it to yourself
2. Try to figure out whose card you have

8. a) Was it easy or hard to
figure out the location of the
seat?
b) Explain why. You may use
Find A Seat one of the following sentence
starters:
a. •This was a good description
because it had…
b. Or
•This was a poor description
because it was missing…

9. One student at a time, share
description.
Everyone else, QUIET PLEASE!

10. Most of the good descriptions
that we just read used something
called a reference point to help
describe their location. Today you
are going to learn how reference
points can help you describe an
object’s position, as well as give
directions from one position to
another.

12. Position – an object’s place or location
• Easy to describe if there is an object or a
marker around!
• Reference point – a marker that helps
describe an object’s position

13. • Good reference points are stationary
or not movable

14. Think-Pair-Share: Why do you
think it’s important to have a
stationary reference point?

15. Check for Understanding: What is the
best reference point to describe the
position of the man?

16. • Reference points are also
necessary because they can help
you determine if an object is
moving.

17. • Reference points are also
necessary because they can help
you determine if an object is
moving.

18. When describing an object’s position,
you need to include 2 things:
• Distance from the reference point (you may
have to estimate)
• Direction from the reference point (left, right,
above, below)

19. Check for Understanding: Describe
the position of the bike.
10 m
5m

20. Rewrite your description of the location
of your desk on the back of the index card
you now have.
• Once again, do NOT put your name on the index card or use
the names of anyone else in the classroom. Your description
of your seat location should still be valid even if there are no
students in the room.
• Remember to choose a reference point and to include the
distance and direction from that reference point

21. Why was it easier to figure out
which card belonged to each
person this time?

22. Independent Practice – page 8L
• Write descriptions of the position of 5 objects
within this classroom. For each one include at
least 1 stationary reference point, as well as the
distance from reference point (estimate) and
direction from reference point.
• At the bottom of the page, make an answer key
(upside down). If you and a classmate finish early,
trade notebooks and see if you can figure out
which objects they are referring to.
