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). |
Sabato, Hollyn, 2023, "Multiplication Array Table", https://doi.org/10.18130/V3/FPMFKP, University of Virginia Dataverse, V8
The manipulative is a physical version of a multiplication chart, shaped similar to a Connect 4 board. The base of the manipulative is a box and the holes along the edges create tunnels for the rods to be inserted, while the holes on the flat face make the rods’ intersection and... |
Pomponio, Erin, 2023, "Fraction Orange", https://doi.org/10.18130/V3/JDRILP, University of Virginia Dataverse, V12
The Fraction Orange is a sphere partitioned into two hemispheres; one hemisphere is further partitioned into fourths, eighths, and sixteenths of the whole; the other hemisphere is further partitioned into sixths and eighteenths. |
Oh, Jennifer, 2023, "3D Vertical Fraction Strips", https://doi.org/10.18130/V3/X1TY1F, University of Virginia Dataverse, V6
This manipulative is a 3D version of fraction strips. Each strip is a rectangular piece that will slide onto one of the three vertical pegs so that the fraction strips can stack vertically (rather than lining up horizontally) and represent the value of a fraction in terms of heig... |
Siegel, Lauren, 2023, "Conic Sections", https://doi.org/10.18130/V3/RUNATA, University of Virginia Dataverse, V4
This is a model of conic slices that is obtained through reverse-engineering parts of a cone, with its dimensions determined by its isosceles triangular frame and the angle of the cross-sectional slices. |
Narciso, Samantha, 2023, "Samantha’s Circles", https://doi.org/10.18130/V3/EOIA3I, University of Virginia Dataverse, V7
Samantha’s Circles is a fraction tool that consists of a collection of rings that are stored on a cylindrical pedestal. Each ring represents a different fraction, and the notches on each ring divide it into equal partitions of the whole. |
