INTRO TO ALG
LT: I CAN CREATE GRAPHS FROM REAL WORLD SITUATIONS
• Set up your journal.
• Homework: Create your own real world situation and create a graph to match it. Explain why your graph matches the situation.
DO NOW:
1. Describe what may have happened. Include details like how fast he was walking.
2. Are all sections of the graph realistic? Explain your thinking.
A-B PARTNER SHARE
• A’s begin to explain their thinking for one minute. B’s DO NOT TALK. (wait for Ms. Huggins signal)
• B’s say “so what I heard you say was…”
• Swap
QUICK SHARE
•What do we think?
EVERYONE NEEDS ONE OF THESE:

HOMEWORK
• Write your own real world situation and create a graph to match
GROUP CHALLENGE
1. Set up this graph in your explore section.
2. As a team, assign your names to each dot. Example:
3. Your challenge:1. Label the axis with
something that makes sense in relationship to who you are. PHYSICAL ATTRIBUTES ARE NOT ALLOWED.

LT: I CAN MAKE GENERALIZATIONS ABOUT MULTIPLYING AND DIVIDING EXPONENTS.
• Set up your journal
• Habit: Listening to Understand
• Homework:
DO NOW:
Write using exponents:
A) B)
C) D)
GROUP SHARE
• Team captain: Starts sharing thinking and go around in your group.
• Recorder: Be ready to share a question your group has if as a team you can’t decide to write using exponents.
• Facilitator: Make sure no one in your group says “IDK”
• Resource Monitor: Keep everyone accountable to the conversation.
EXPLORE: POWERS OF TWO
29Base
Exponent
Power 52
QUICK MODEL
• equations using only powers of two:
64
22 ∙ 24=26
(2 ∙2)(2∙2 ∙2∙2)=26
POWERS OF 2
P-15
B: 16 ÷ 8 = 2
A: 8 × 4 = 32
D: 8 ÷ 8 = 1
C: 8 ÷ 16 = ½
Task: Write each of the calculations in your EXPLORE using only the powers of 2. (Not just the answer, but the whole calculation)

WHAT IS HAPPENING EACH TIME?
• Take a minute to look over your work so far. In words explain a pattern you notice that is happening to the exponents when you multiply.
• Every time you multiply exponents with the same base…
A-B PARTNER WORK
• Partner A starts sharing. Explain your work with your partner.
• Partner B listens. Ms. Huggins will give you a signal then “ what I understand about your work is…”
• Swap
• As a partner team, work together to solve as many as you can!
