Anticipatory Set: Hello
Hans.
How
was
your
Halloween?
What
did
you
dress
up
as?
Did
you
get
a
lot
of
candy
this
year?
Today
you
and
I
are
going
to
play
a
game
that
will
help
with
our
math
facts
more
and
do
a
few
other
activities.
Lets
start
today
off
with
a
store.
You
are
going
to
pretend
that
you
are
buying
a
variety
of
different
things.
Mostly
candy,
because
it
was
just
Halloween.
You
are
going
to
look
at
this
sheet
that
I
have
for
you,
and
choose
two
things
that
you
want
to
buy.
(The
sheet
will
be
a
list
of
different
candies
and
there
picture
with
an
amount
next
to
them.
The
student
will
choose
two
types
of
candy
and
have
to
add
them
up
together.
This
way
he
will
be
working
on
his
basic
facts
while
also
choosing
objects
or
numbers
he
is
familiar
with.)
Hans
choose
two
types
of
candy
that
you
want
for
Halloween.
Ok,
you
choose
skittles
and
Hershey.
Do
you
see
the
number
that
is
next
to
the
picture
of
these
candies?
I
want
you
to
add
up
these
two
numbers
to
see
how
many
pieces
you
will
get
from
the
store.
(Continue
having
the
student
choose
different
types
of
candy
to
add
together
to
find
the
sum.
Do
this
activity
for
about
five
minutes.
Also,
have
counters
available
to
group
together
if
needed.)
Objective: Addition
#6:
The
student
can
complete
addition
facts
(sum
0‐18)
We
will
also
be
working
on
learning
the
commutative
property.
I
will
explain
how
the
property
works
and
how
it
will
make
it
easier
when
learning
and
mastering
the
basic
facts.
We
will
be
going
through
a
few
different
activities
to
help
strengthen
my
understanding
of
how
he
is
doing
with
his
basic
facts.
Instructional Input/Modeling: Alright,
now
that
we
got
ourselves
ready
for
the
lesson
lets
begin
with
using
these
Cuisenaire
Rods.
I
want
you
to
tell
me
what
you
see
when
I
put
this
group
of
numbers
together
and
this
group
of
numbers
together.
(Place
the
number
6
rod
next
to
the
number
4
rod.
Next
to
that,
place
a
number
4
rod
first
and
the
number
6
rod
second.)
Hans
what
do
you
see
with
these
numbers?
(Allow
for
response)
What
is
the
sum
of
the
first
addition
problem?
(Point
to
the
first
set
of
Cuisenaire
Rods.)
Great
job.
Now,
what
is
the
sum
of
the
second
problem?
(Allow
for
response)
You
are
doing
great
Hans.
Both
of
the
problems
had
the
same
sum.
Did
they
have
the
same
addends?
(Allow
for
response)
An
addend
is
one
of
the
numbers
in
the
problem
if
you
forgot
what
it
was.
Since
we
know
that
both
problems
have
the
same
addends,
but
in
a
different
order,
they
equaled
the
same
sum.
This
is
called
the
Commutative
property
in
math.
When
you
have
the
same
numbers
added
together,
but
in
a
different
order,
they
still
equal
the
same
thing.
Lets
do
a
few
more
so
we
can
understand
it
better.
(Take
the
next
ten
or
so
minutes
to
show
Hans
a
few
more
commutative
properties
with
his
basic
facts.
Use
the
Cuisenaire
Rods
as
visuals
to
explain
how
both
equations
are
really
the
same
things.
Stop
and
explain
if
student
is
not
understanding
the
concept.)
Nice
work
so
far
Hans.
So
if
I
were
to
give
you
a
problem
that
is
3+7
and
you
know
the
answer,
I
should
be
able
to
give
you
the
problem
7+3
and
you
also
should
be
able
to
solve
the
problem.
We
are
now
going
to
have
the
first
number
in
the
problem
not
always
be
the
largest,
because
you
should
know
that
you
could
flip
the
numbers
around
to
solve
the
problem
still.
Check for Understanding/Guided Practice I
want
to
now
move
on
to
our
next
activity.
(Bring
out
a
baggy
with
a
stack
of
cards
in
it.
The
cards
are
part
of
the
next
game
you
will
be
playing.
Start
laying
the
cards
on
the
table
in
rows
and
columns.
Make
it
neat,
because
the
game
is
a
memory
game.)
We
are
going
to
be
playing
the
memory
game.
Instead
of
trying
to
look
for
the
different
shapes
or
pictures
on
the
back
of
the
cards
you
are
going
to
be
trying
to
find
the
commutative
of
the
first
card
you
flip
over.
For
example,
if
I
choose
this
card
(Point
to
a
card
on
the
table)
I
will
flip
it
over
and
have
to
give
the
answer
to
the
problem
on
the
back.
Next,
I
will
flip
over
another
card
to
see
if
it
matches
with
the
first.
Remember
it
will
not
match
exactly,
but
it
will
be
the
opposite
of
what
is
written
on
the
first.
The
card
should
have
the
same
sum
as
the
first
card
you
flip
over.
If
you
answer
the
problem
on
the
back
of
the
cards
correctly,
you
get
to
keep
the
cards
and
have
a
second
turn.
If
you
do
not
answer
it
correctly,
you
have
to
wait
for
the
next
turn
to
play
again.
Understand
the
rules.
(If
needed
repeat
and
clarify
the
rules
of
the
game.)
Lets
see
who
can
get
the
most
cards
in
their
stack.
You
can
go
first
and
flip
over
one
cards.
What
is
the
sum
of
that
card
Hans?
Great
job
Hans;
now
flip
over
another
to
see
if
you
got
the
commutative
of
the
first
one.
(Continue
taking
turns
to
find
the
pairs
in
the
memory
game.
If
the
game
is
over
too
quickly
shuffle
the
cards
and
play
again.
It
will
work
on
his
understand
of
the
basic
facts
and
the
cumulative
property
as
well.)
(If
you
end
early
work
on
the
tangram
worksheets)
Closure: Great
work
today
Hans.
I
think
you
are
doing
awesome
with
your
basic
facts.
Lets
review
quickly
what
we
learned
today.
What
is
the
cumulative
property?
(Allow
for
response)
Your
right.
It
is
when
you
have
an
equation
with
the
same
numbers
but
in
a
different
order.
Lets
bring
out
our
chart
and
fill
in
the
remainder
of
it
with
this
color.
You
know
all
of
your
basic
facts
now.
I
am
sure
that
if
I
asked
you
any
one
of
the
problems
on
this
sheet
you
could
give
me
the
answer
right
away.
Right?
Great
job
today
Hans.
Next
time
we
meet,
we
are
going
to
be
working
on
subtraction.
We
are
going
to
learn
an
easier
way
to
take
things
away
from
a
larger
number.
That
is
all
I
have
for
us
today.
We
can
head
down
stairs
to
meet
up
with
our
friends.
Evaluation: Today
I
am
going
to
evaluate
Hans
by
seeing
if
he
still
knows
his
facts
or
if
he
was
just
starting
to
memorize
them
the
last
time
we
were
together.
I
will
be
watching
how
well
he
understands
the
new
concepts
that
I
have
given
him
at
the
beginning
of
the
lesson.
I
will
also
be
seeing
how
well
he
notices
the
concept
of
commutative.
When
we
fill
out
the
remainder
of
the
Basic
Fact
sheet
I
will
know
if
he
really
understand
them
or
if
he
has
just
memorized
or
is
still
counting
in
his
head.

Reflection: Today
the
time
just
flew
by.
Hans
did
very
will
with
the
review
of
the
basic
facts
at
the
beginning
of
the
lesson.
You
can
really
see
that
he
is
working
on
his
basic
facts
either
at
home
or
in
school.
When
ever
I
bring
in
a
game
his
basic
facts
seem
to
improve
even
more.
He
likes
to
have
a
reason
to
give
me
the
answer
in
a
timely
manner.
He
always
wants
a
reward
for
getting
the
answer
correct.
We
used
the
Cuisenaire
Rods
when
I
introduced
the
commutative
property
and
it
seemed
to
help
him
visualize
what
I
was
explaining.
He
caught
on
very
quickly
and
starting
making
his
own
addition
sentences
with
the
Rods.
The
memory
games
worked
very
well
with
helping
him
understand
the
commutative
property
and
how
it
really
work.
Overall,
the
day
went
very
well.
I
was
curious
to
see
how
my
next
lesson
was
going
to
work
for
him
so
I
asked
him
a
few
subtraction
problems.
He
is
learning
about
subtraction
in
school
right
now,
so
he
knows
a
lot
more
then
I
planned
for.
This
next
lesson
will
probably
be
too
easy,
but
it
will
give
me
a
good
base
to
see
where
to
start.
He
is
excited
about
subtraction;
he
says
he
likes
it
more
than
addition.
Today’s
lesson
was
a
success
and
we
filled
in
his
Basic
Fact
sheet.
