Enduring Understanding
Each digit in a number has a specific value.
Numbers can be decomposed in various ways - a three-digit number e.g. 123 has
a value of 123 ones, 12 tens, and 3 ones, or 1 hundred and 2 tens and 3 ones.
The value of a digit is determined by its location in a number.
Placing numbers in groups of ten is the basis of the base-ten system. Taking
apart and combining numbers in terms of groups of ten helps develop mental
math abilities.
Rounding is a form of estimation that changes numbers in a problem to make it
easier to compute mentally.
Estimation strategies have two main purposes. They are used for prediction
and to determine reasonableness of an answer.
Numbers have patterns and rules can be applied to solve equations with an
unknown.
Data can be shown in many different ways. The same data can be shown in
different graphical representations.
Arrays and repeated addition are ways to illustrate multiplication.
Multiplication using area models shows the distributive property and partial
products. Multiplication should begins with models and move to the written
record.
There are two concepts of division, one involving partitioning or fair shares
and the other related to measurement or repeated subtraction.
Divison with remainders involves thinking about what is to be done with the
remainder e.g. cookies can be kept but extra children needing transport on a
trip cannot be left behind.
There is a relationship between multiplication and division that supports
fluency with facts.
Multiplication and division problems can be made easier by the development of
a story to connect the numbers.
