no wonder adding up is tricky…

If you are asked to do an addition you are really being asked to

add the coefficients of a polynomial equation

Look , here’s what 326 really means:

polynomial1

3 is the coefficient of the second power, 2 is the coefficient of the first power and 6 is the coefficient of the zeroth power.

THAT’S WHY ITS HARD FOR LITTLE KIDS TO UNDERSTAND AT FIRST

good adder results

Here’s a list of the main ideas that are useful in becoming ‘a good adder’ generated from the previous post:

interpreting the meaning of numerals and operation symbols

to know the complements to and from 10 and to and from 5

immediate recognition of number pairs as complements 

the transference of the above to all other decades and patterns

familiarity with the inner structure of numbers

scanning problems first as a  fundamental activity

awareness of equivalent transformations after the scanning process

the power of  visual images of relationships and processes within memory

total awareness of the commutative rule 

total awareness of our number system including place value

transformation is OK and is allowed

generation of own recording styles
