Day 37: Write Algebraic Expressions (this is hard
concept for lots of kids)
 Vocab:
o algebraic expression – mathematical phrase
that includes at least one variable
o variable – letter or symbol that stands for one
or more numbers
 Go 7.3 Discuss variables
 Task: You tube:

street live caricature – Or Weitzman
 Discuss what a caricature is; how much did he make
in a day, in a week; don’t know how many people he
drew (variable); write expression. Task in 7.3 – artist
made $5 for each person
 Write expressions from words. Teach that “than” is a
magical word (Example 2) – it “flips”. 9 less than 14 is
14 – 9 (this idea of expressions from words is a
difficult concept for students)

o “Mitchell is saving money to buy an MP3
player that costs $120. He starts with ($25)
and each week he saves the same amount
($9). How much money will Mitchell have
saved after 8 weeks? After how many weeks
will Mitchell have saved enough money to buy
the MP3 player? (25 + 9w; where w = 8)
