MULTIPLICATIVE THINKING
- The process of renaming,
comparing and calculating with
the various fraction forms and
establishing proportional
reasoning
- Arrays help with why the
parts are added, place value
and renaming in multiplication,
addition and subtraction
- Arrays provide understanding
of how ones multiply with ones
to give ones, ones multiply with
tens to give tens, tens multiply
with tens to give hundreds, and
so on
- Developing the concepts, basic facts and
algorithms used in multiplication and
division
- critical to develop
algebraic thinking for
later formal algebra in
high school
- Renaming occurs between mixed
numbers and improper fractions
- MULTIPLICATION
- Uses arrays
- Uses place
value
- repeated addition
e.g. shows 3 fives
and 5 threes and
moves away from
5 + 5 +5
