Math Flashcards
Schemas are located
in Left hemi (facts and details)
assimilation (fits exisiting) of information
left hemi
accomodation (makes new) of information
right hemi
If kid has math issue/disability usually because of basic issue with _______.
QUANTITY
DO NOT have a good understanding of quantity. Shows up early mapping number to objects one-to-one correspondence (1 m&M)
Grouping (classification of object)
how to group things together
Seriation-
sequential processing
conservation –
about know no matter what you do to transform an object the amount remains the same.
Quantity representation is _______
**symbolic ***– knowing that numbers mean things 42 is 42 not 4+2
Pre-Skills ,subitizing = arithmetic (making bigger or smaller)
size differences
pre-skill, ordinality
(< or >)
pre-skill, arithmetic
(making bigger or smaller)
Math is ____ based – taught through ______ ______
Skill,
direct instruction
Early instruction - Concrete Objects
apple + apple = 2 apples)
Semi-Concrete Symbols
(// + / = ///) - dots, slashes ect.
Abstract Numbers
(4 + 2 = 6) - NUMBERS are ABSTRACT (it is only though quantity, number association do they gain meaning)
Area of brain to map visual aspect of numbers to numbers –
angular gyrus (zones of overlapping)
MAX
(small number added to big number – start at 2 and add seven on)
MIN
Big number added to small number - start at 7 and add two on
Math Fact automaticity
(relying on memory for math facts= LEFT BRAIN in medial temporal lobe)
Thinking about (ie thinking about 9+2) =
dorsal stream
Fact /automatic–
ventral stream (knowing the answer by fact)
Kids with math problems struggle with
left hemisphere dysfunction
Rourke – in kids with math disabilities
(non verbal disabilities) = math SLD
Rourke - Decline in academics as age because …
more facts and details focused on in young age but more abstract thinking as student ages.
Gerstmann Syndrome ( LEFT parietal damage ):
Neuropsychological Disorder known primarily in patient populations, but also occurs in SLD
symtoms of Gerstmann syndrom
Finger agnosia,
Left/right confusion
dysgraphia
Quantity-Symbol (Number) Relationships - connecting numbers with symbols –
super marginal gyrus (left hemi)
Spatial Processing (Multi-step Problems) –
right hemi
Sequential/Working Memory –
frontal and dorsal lateral, brocas
Visual-Spatial-Motor Integration graphomotor –
compute (doral stream) get it automatic (ventral stream, needed for quick recall)
Semantics
(meaning – left central) and syntax (order – more frontal)
Words- number association
working memory
Novel problem solving – fluid reasoning
right brain, frontal activity
All Computation Components
MORE Executive – brain boss executive function
