Set Tool by mathies for Android APK

Description

Sets of objects can be generated randomly or designed by the user. Sort and classify objects. Create patterns. Represent, compose and decompose whole numbers, tenths, and fractions. Explore experimental probability.

Mathematical Concepts:

Create visual representations that help explore mathematical thinking related to:

Subitizing (instantly seeing how many)

Sorting by attributes (shape, colour, size, with face/no face)

Counting principles, e.g., conservation of number

Skip counting by 2s, 5s and 10s

Representing, comparing and ordering numbers

Composing and decomposing numbers

Using anchor values of 2, 5, and 10

Modelling operations with numbers

Demonstrating multiplicative thinking

Exploring number patterns and concepts

Creating patterns

Exploring probability and randomness

Features:

Create a user-designed set of objects by dragging into the workspace

Auto-generate a random set of objects by specifying a number

Auto-generate a new set while conserving count and selected attribute options

Select an object or set of objects by drawing a marquee around them

Copy selected objects

Change the attributes of selected objects (shape, colour, size, facedness) specifically or randomly

Organize objects using Ten frames or Frames of Tenths

Scramble or align objects in the workspace

Increase and decrease the object size

Use the multiplier button to set the number of objects (1, 2, 5, 10) to drag to the workspace

Use the Object Count button (#) to check to see how many objects are in the workspace

Step through a history of your work with the undo/redo buttons

Communicate your thinking or highlight various features of your representation using the built-in annotation tool
