Subject: Place value, number placement

Suggestions for teaching place value:

I read to my 5th grade students "How much is a million?"  They enjoyed
this story and wanted to write their own version.  Lower level
students could listen to the same story but as a class write "How much
is a thousand?" etc...

I keep a place value chart on the board all year.  It is student
created with different colored paper for each period.  I then use Uno
cards with magnets on the back as manipulatives.  Students love to use
them for rounding, adding and practicing reading numbers.  I also will
post a "number of the day" and have them review 4th grade skills (by
writing in their math journal) They respond to the number by using it
in a fact, estimation or data.  For example, the number 1000 would
explain how many students in our school.  The number 250 would show
how many students in our 5th grade and 30 would be an estimation of
how many kids ride on their bus and 10 would be how many 5th grade
teachers we have etc...  Once we have worked up to a number that some
students struggle understanding, we post on the bulletin board "how
much is_______" with the number and its representations on display,
according to our class mathmatitions.

For the special needs students I do a greater than, less than, equal
to project.  I will name a representation such as "the number of
people that live on their street"  and they tell me if it is greater
than, less than or about equal to the number given.  This works for
all levels because they use real life connections.  I will also ask
them to explain a situation where there is more than, less than and
equal to...
