STUDENT OUTCOMES

Students communicate mathematic ideas effectively and efficiently.

ENTERING THE CLASSROOM EACH DAY

• LEAVE YOUR BOOKBAG IN YOUR LOCKER!

• GET YOUR CALCULATOR AS YOU ENTER THE ROOM.

• TAKE YOUR ASSIGNED SEAT IMMEDIATELY. DO NOT SOCIALIZE

ONCE YOU ENTER THE ROOM.

• GET OUT YOUR NOTES, HOMEWORK, PENCIL, PAPER, EUREKA

WORKBOOK, CALCULATOR, COMPASS AND PROTRACTOR AND

QUIETLY COMPLETE THE DO NOW ASSIGNMENT.

DO NOW

1. THE NUMBER WRITTEN ON YOUR WORKBOOK IS YOUR

CALCULATOR NUMBER. GET YOUR CALCULATOR!

2. COMPLETE THE ASSIGNMENT TO THE RIGHT

( 5 MIN.)

PICTIONARY• DETERMINE WHO WILL BE PARTNER A

AND WHO WILL BE PARTNER B

• YOU WILL EACH NEED:

• PENCIL

• ONE PIECE OF BLANK COMPUTER

PAPER

• POSITION YOUR DESKS BACK-TO-BACK

YOU WILL WORK

WITH A

PARTNER.

RULESDRAWER ( A )

• YOU MAY NOT ASK ANY QUESTIONS.

• YOU MAY NOT LOOK AT THE PICTURE YOUR PARTNER HAS OR ANY PIC THEY MAY DRAW.

• YOU MAY ONLY REQUEST THAT THE DIRECTION BE REPEATED. YOU MAY NOT TALK OTHERWISE!

CALLER ( B )

• YOU MAY NOT LOOK AT THE DRAWING YOUR PARTNER IS MAKING

• YOU MAY NOT TELL YOUR PARTNER IF THEY ARE RIGHT OR WRONG.

• YOU MAY ONLY DESCRIBE THE PICTURE YOU ARE GIVEN.

• YOU MAY NOT DRAW ANY EXAMPLES.

POINT

IDENTIFIES A POSITION IN SPACE.

NO LENGTH, WIDTH, OR DEPTH.

LABELED USING A SINGLE CAPITAL LETTER.

line - made up of points (has no thickness). Named by 2 points on the line

or a lowercase script letter

𝑀𝑃 𝑃𝑀 𝑁𝑃 𝑃𝑁

6

ray - Part of a line

Has an endpoint and extends indefinitely in one direction.

Use 2 points to name a ray, starting with the endpoint

𝐴𝐵𝐴𝐶

segment - part of a line with 2 endpoints

Name using the 2 endpoints

𝐴𝐵 𝐵𝐴

plane - a flat surface made up of points.

Named by a capital script letter or 3 noncollinear points in the plane

Throughany three noncollinear points there is exactly one plane.
