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. No Más Caídas is Spanish for No More Falls. The design was inspired by games played in the Dominican Republic,... |
Kaupp, Lauren; Philippoff, Joanna; Seraphin, Kanesa; Lurie, Matthew, 2023, "Wave Prints", https://doi.org/10.18130/V3/ILBUSG, University of Virginia Dataverse, V4
This activity, first published by the National Science Teaching Association (NSTA), uses a wave tank to create a standing wave and capture its physical profile in the form of a wave print. Students create a standing wave in a wave tank and record the profile of the wave by making a print of it. This is accomplished by dipping an absorbent sheet of... |
Garofalo, Joe, 2023, "Solenoid", https://doi.org/10.18130/V3/QKHVG8, University of Virginia Dataverse, V1
The Make to Learn solenoid can be used to explore principles of electricity and magnetism. This solenoid can be used with the Linear Motor in the Engineering Section. |
Watts, Jo; Bull, Glen, 2023, "3D Cam Explorer", https://doi.org/10.18130/V3/L63YMY, University of Virginia Dataverse, V3
This model is designed to enable students to explore and understand the way in which the motion of a series of cams in a mechanical wave machine can simulate the motion of a wave. A cam translates rotary motion into linear motion. A circular cam reproduces the circular motion of a particle of water in an ocean wave. The mechanical motion of the cam... |
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). The Trigonometry Angle Formulas comprises four right-angled triangles of different dimensions that are joined to form a rectangle. The inscribed triangle is a right angle that touches all four sides. By labeling... |
Bull, Glen; Watts, Jo, 2023, "Linear Motor", https://doi.org/10.18130/V3/98YZHR, University of Virginia Dataverse, V2
The Make to Learn Linear Motor can be used to explore principles of electricity and magnetism while providing historical context. The linear motor is a functioning electric motor constructed from a coil of wire and a permanent magnet. The Make to Learn Linear Motor is inspired by the Charles Page Motor patented in 1852. This early electric motor pr... |
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... |
