Addition belongings of equality - ANS-If a=b, then a+c=b+c
Additive identification property of zero - ANS-a+0=zero+a=a
Array - ANS-useful representation of multiplication concepts and geometric ideas. 3 rows
and four columns = three x four or 3 by way of four array
Associative belongings of addition - ANS-(a+b)+c=a+(b+C)
Associative assets of multiplication - ANS-(ab)c=a(bc)
Commutative property of addition - ANS-a+b=b+a
Commutative assets of multiplication - ANS-ab=ba
Compacting - ANS-organizations of students who can skip steps and flow fast due to the fact
they've more superior math fluency
repayment - ANS-borrowing pieces of one range to catch up on another to make it easier to
solve
Distributive property of multiplication over additions - ANS-a x (b + c) = a x b + a x c
Division property of equality - ANS-if a =b then c does now not = 0 then a/c=b/c
Existence of additive inverses - ANS-For each a there exists -a in order that a + (-a) = (-a) +
a=0
Existence of multiplicative inverses - ANS-for each a=zero there exists 1/a so that a x 1/a x a
=1
bendy grouping - ANS-businesses exchange from each day and even within a category
period
Greatest Common Factor (GCF) - ANS-best aspect that dives numbers
hobby grouping - ANS-corporations of students based on college students hobby
Inventive techniques - ANS-techniques in which students invent methods to resolve
complicated issues. They involve using purpose and understand to get to an give up result.
Ex. Partitioning, reimbursement
Iteration - ANS-repeating the identical steps over and over again. Anything this is sequential
in operation is that this.
Ex. Following the steps for the standard set of rules further
Least not unusual more than one (LCM) - ANS-smallest positive variety that is a more than
one of two or greater
Math Fluency - ANS-CRA-> Concrete (tiling base ten blocks), Representation (images,
photographs, charts), Abstract (2x5=10)
Math fluency - ANS-fee, accuracy, automaticity, flexibility
Multiplication belongings of equality - ANS-If a=b, then ac=bc
multiplicative identity assets of one - ANS-a x 1 = 1 x a = a
Partioning - ANS-taking massive numbers and splitting them into small, workable gadgets
reflexive assets of equality - ANS-a=a
Standard algorith - ANS-precise approach of computation that is conventionally taught for
solving precise mathematical problems the use of wellknown notation in:
-exchanging, regrouping, lengthy division, long multiplication , common, area, quantity
subitize - ANS-understanding the variety by way of looking at a illustration of the range.
