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

When you get your new card:
1. Silently read it to yourself
2. Try to figure out whose card you have
Find A Seata.b.
8L
a) Was it easy or hard to figure out the location of the seat?
b) Explain why. You may use one of the following sentence starters:•This was a good description because it had…
Or•This was a poor description because it was missing…
One student at a time, share description.
Everyone else, QUIET PLEASE!
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.

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
• Good reference points are stationary or not movable
Think-Pair-Share: Why do you think it’s important to have a stationary reference point?
Check for Understanding: What is the best reference point to describe the
position of the man?
• Reference points are also necessary because they can help you determine if an object is moving.
• Reference points are also necessary because they can help you determine if an object is moving.
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)
Check for Understanding: Describe the position of the bike.

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