4.OA.3 Solve multistep word
problems posed with whole
numbers and having wholenumber answers using the
four operations, including
problems in which
remainders must be
interpreted. Represent these
problems using equations
with a letter standing for the
unknown quantity. Assess the
reasonableness of answers
using mental computation
and estimation strategies
including rounding.
4.OA.4 Find all factor pairs for
a whole number in the range
1–100. Recognize
that a whole number is a
multiple of each of its factors.
Determine whether a
given whole number in the
range 1–100 is a multiple of a
given one-digit number.
Determine whether a given
whole number in the range 1–
100 is prime or composite.
4.OA.5 Generate a number or
shape pattern that follows a
given rule. Identify apparent
features of the pattern
that were not explicit in the
4.NBT.5 Multiply a whole
number of up to four digits by
a one-digit whole
number, and multiply two
two-digit numbers, using
strategies based on place
value and the properties of
operations. Illustrate and
explain the calculation by
using equations, rectangular
arrays, and/or area models.
4.NBT.6 Find whole-number
quotients and remainders
with up to four-digit
dividends and one-digit
divisors, using strategies
based on place value, the
properties of operations,
and/or the relationship
between multiplication and
division. Illustrate and explain
the calculation by using
equations, rectangular arrays,
and/or area models.
