Mini Unit 4: Lesson 2
There are 36 students
participating in the
math challenge teams
this year. There is an
even number of teams.
The teachers want the
greatest number of
teams possible with at
least 5 students per
team. How many teams

proof
Mini Unit 4: Lesson 3
Lisa says it is
possible to draw a
triangle that has
more than one right
angle. Miguel says
this is impossible.
Who is correct?
Explain your
answer.
Mini Unit 4: Lesson 3
Compare and Contrast Polygons
Targets:

Mini Unit 4: Lesson 4
Logic:
Marita wrote a 3-digit number.
The digit in the tenths place is 5
less than the digit in the ones
place. The digits in the
hundredths place is the sum of
the digits in the tenths and the
ones place. What are the
possible numbers?
Mini Unit 4: Lesson 4

Making Change:
Deirdre bought one pencil for 54¢, one
book for $4.35, and one book on sale
for 65¢ off of $4. She paid with one $10
bill and six coins and received two $1
bills and one coin as change. If she did
not receive a half-dollar coin, what
coins did she use to pay? Explain.
