Notes
Solve problems by using
visual fraction models or
equations to represent
the problem. Use
benchmark fractions and
number sense of
fractions (0, ½, 1) to
estimate mentally and
assess the
reasonableness of
answers.
For example, recognize
an incorrect result 2/5 +
½ = 3/7, by observing
that 3/7 < ½.
Use visual fraction
models or equations to
represent the problem.
For example, interpret ¾
as the result of dividing 3
by 4, noting that ¾
multiplied by 4 equals 3,
and that when 3 wholes
are shared equally
among 4 people each
person has a share of size
¾. If 9 people want to
share a 50-pound sack of
rice equally by weight,
how many pounds of rice
should each person get?
