Going Mental
I'm not very coordinated
Fragmenting
Constructs
This is SO hard!
100
This mental action involves making equal sized pieces AND exhausting the whole.
What is partitioning?

This Add+Vantage assessment can be administered in a whole class setting using a paper-pencil format.
What is the units coordination assessment (UCA)?
100
These two levels BOTH align with construct 0.
What are levels 1 & 2?
100
How many constructs are there for measuring fraction knowledge?
6

This dessert food is the preference of 16/23 participants.
What is cake?

This video deomonstrates that this student does not yet have which mental action?
What is Disembedding
200
How many levels of units coordination are there?
3
200
In this level of fragmenting a student can share mulitple items with multiple people.
What is fragmenting level 5?
200
What are the indicators that a student has moved from a construct 0 to a construct 1?
OR vs. AND
200
This is the mathematical model preferred by most.
What is pictoral modeling?
300
This mental action undergerds all other mental actions.
What is unitizing?
300
How many levels of units would a student need to coordinate to execute this task successfully?
A landscape architect bought 5 tons of soil, knowing that each flowerbed in the garden she was designing
required 3/5 of a ton of soil. How many flowerbeds can she fill with soil?
3 levels
300
This level of fragmenting is aligned with the mental action of splitting.
What is Level 4?
300
This set of constructs are associated with Fractions as a Measurement Concept.
What are Constructs 3, 4, & 5?
300
This author was a co-author on the "orange book," "purple book," and "red book."
Who is Bob Wright?
400
This video is a demonstration of this mental action.
What is splitting?
400
Which tasks on the UCA are designed to measure 1, 2, and/or 3 levels of units coordination?
All of them.
400
Fragmenting level 3 aligns with which mental action?
What is partitioning?
400
This mental action takes place for the first time in construct 4?
What is Splitting?

This researcher is the author of the reorganization hypothesis.
Les Steffe
500
The theory that students perform many of the same mental actions to make sense of fractions that they would perform to make sense of whole numbers.
What is the reorganization hypothesis
500
Draw a model to show 3 levels of units coordination (you must use fractions).
500
What level of fragmenting needs to be activated in order for the student to successfully complete this task?
Fragmenting Level 5
500
At this construct students begin to name parts as fractions.
What is construct 2

Jenny Scholla
Also acceptable, the lady who has been giving the assessments.
