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 multiplication product visible. Multiplicative thinking is particularl... |
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 height. The fractions are mounted on one platform with the 1 (whole) alway... |
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. All conic sections are defined by the relationship of their locus of points to fixed points known as foci. Ellipses arise from a locus of points t... |
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. Fractions can be thought of as parts of a whole, ratios, and division. Students should be able to understand fra... |
Bull, Glen, 2023, "Praxinoscope", https://doi.org/10.18130/V3/1U0E4N, University of Virginia Dataverse, V2
In this project, students will assemble a model of a praxinoscope, observe essential components of animation machines, and determine how the essential components work together to create the illusion of animation. Over time, the development of several physical animation machines extended storytelling capabilities, leading to the birth of cinema. Thi... |
Borowczak, Andrea; Borowczak, Mike, 2023, "Measuring Cups", https://doi.org/10.18130/V3/II0CVB, University of Virginia Dataverse, V3
Students engaging with this basic manipulative can first build an understanding of volume while using a single material and then density when using multiple materials. The Measuring Cups is a set of five nesting, polygonal containers with flat bottoms and tops. These measuring containers hold, and are labeled with, common US customary volume units... |
