Reed, Rachel, 2024, "Pre-K Star Math Manipulative", https://doi.org/10.18130/V3/FCQUI7, University of Virginia Dataverse, V3
The design is for 15 star manipulative. 5 large blue stars, 5 medium green stars, 5 small yellow stars. All stars have holes in the center and can be stacked on one of two base boards. The design is based the book How to Catch a Star by Oliver Jeffers. The book provides the conte... |
Giangrande, Erika, 2024, "Balancing Parts and Wholes", https://doi.org/10.18130/V3/GBLDG6, University of Virginia Dataverse, V1
When a scale is equal on both sides, it balances out. The creation of the scale was to show how two parts of an equation (addends) equal the whole number. When the two parts are equal to the whole number. The scale balances out. This shows that both sides are equal to one another... |
Veniero, Alexa, 2024, "Rotating Vertical Number Line", https://doi.org/10.18130/V3/FZXLK3, University of Virginia Dataverse, V1
The design is a vertical number line that moves up and down with the rotation of a gear. This was designed because a number line that goes up and down more accurately represents the concept of addition and subtraction, therefore making it easier for users to make sense of the con... |
Mooney, Elizabeth, 2024, "Fractions Waffle", https://doi.org/10.18130/V3/HECQ0P, University of Virginia Dataverse, V1
The Fractions Waffle is an interactive way for students to visualize how fractions are formed. The user is supposed to demonstrate the concept of a set or quantity when working with fractions with this manipulative. This is through the use of taking apart the Fractions Waffle’s s... |
Forte, Samantha, 2024, "Subitizing Butterfly", https://doi.org/10.18130/V3/SG1BLG, University of Virginia Dataverse, V1
The design is a butterfly, as this is a bug with naturally balanced halves. There are 10 pegs on each side, making 20 altogether. Each individual wing is divided into two parts of 5, which is the same arrangement as seen on dice. This allows the teacher to choose how to use the m... |
Kose, Norah, 2023, "Decimal Snake", https://doi.org/10.18130/V3/3VDUDI, University of Virginia Dataverse, V6
The body of the Decimal Snake consists of 10 pieces. Each piece is equally partitioned into 10 parts. Once the “whole” of the Decimal Snake is designated, then each body part represents one-tenth of that whole, and each partition of a body part represents one-tenth of one-tenth (... |
Bonvini, Laura, 2024, "Turtle Bug", https://doi.org/10.18130/V3/M1ICDB, University of Virginia Dataverse, V2
The bug counter can be used to compose or decompose numbers to create smaller or larger quantities. The counter and the pegs are quite large for smaller hands to grasp. |
Baumann, Kimberly & Sondej, Elizabeth, 2023, "Minute Minis", https://doi.org/10.18130/V3/ZGC6UV, University of Virginia Dataverse, V8
Minute Minis are essentially relabeled fraction circles: the whole is labeled ‘1 hour,’ the halves are each labeled ’30 min,’ the fourths are labeled ’15 minutes,’ and the twelfths are labeled ‘5 min.’ |
Davidson, Jessica; Mateo, Mayrobi, 2023, "No Más Caídas", https://doi.org/10.18130/V3/IFKSBY, University of Virginia Dataverse, V5
No Más Caídas is a manipulative that helps children learn to count by forming groups of fives and tens (i.e., by subitizing), generalize strategies for composing and decomposing numbers, and develop a sense of the nested nature of numbers. |
Siegel, Lauren, 2023, "Trigonometry Angle Formulas", https://doi.org/10.18130/V3/LJ9PB2, University of Virginia Dataverse, V5
Making sense of trigonometric identities; To help students derive and thus make sense of the trig identities, sin (a + b) and cos (a + b). |
