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)?
These two levels BOTH align with construct 0.
What are levels 1 & 2?
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
How many levels of units coordination are there?
3
In this level of fragmenting a student can share mulitple items with multiple people.
What are the indicators that a student has moved from a construct 0 to a construct 1?
OR vs. AND
This is the mathematical model preferred by most.
What is pictoral modeling?
This mental action undergerds all other mental actions.
What is unitizing?
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
This level of fragmenting is aligned with the mental action of splitting.
What is Level 4?
This set of constructs are associated with Fractions as a Measurement Concept.
What are Constructs 3, 4, & 5?
This author was a co-author on the "orange book," "purple book," and "red book."
Who is Bob Wright?
This video is a demonstration of this mental action.
What is splitting?
Which tasks on the UCA are designed to measure 1, 2, and/or 3 levels of units coordination?
All of them.
Fragmenting level 3 aligns with which mental action?
What is partitioning?
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
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
Draw a model to show 3 levels of units coordination (you must use fractions).
What level of fragmenting needs to be activated in order for the student to successfully complete this task?
Fragmenting Level 5
What is construct 2
Who is this?
Jenny Scholla
Also acceptable, the lady who has been giving the assessments.
