Description

The Rekenrek tool helps to build a deeper understanding of numberconcepts and relationships. Mathematical Concepts:Make visualmodels that help explore mathematical thinking related to:•understanding number relationships using anchors of 5 and 10•representing numbers in different ways, composing and decomposingnumbers• subitizing (instantly seeing “how many”)• countingprinciples• understanding addition and subtraction• developingmultiplicative thinking• visualizing division facts Features:•Adjust the number of rows.• Choose a background colour and beadcolours.• Drag the rods to compare values.• Hide beads with one ofthe two resizable shades. Shades can be repositioned to focusattention.• Communicate your thinking or highlight various featuresof your representation using the “pencil” button.

Money by mathies 3.0.1 APK
OAME
Represent various money amounts using these realistic images ofCanadian coins and bills.Mathematical Concepts:Create visualrepresentations that help explore mathematical thinking relatedto:● Estimating and counting the value of a collection of money●Skip counting using the value of one of the coins or bills●Representing the relationship between coins and bills. (e.g., Thereare 8 quarters in a toonie)● Adding and subtracting money amountsby making simulated purchases and providing change● Exploring placevalue and unit conversions● Multiplicative thinking● Anchors of 2,5 and 10 Features:● Customize the allowable set of currencies ●Resize images for easier manipulation● Show labels indicating thevalue of each currency● Set the units of these labels to indicatedollars or cents● Set the number of copies to drag from the cashdrawer ● Step through a history of your work with the undo/redobuttons● Check to see how many of each type of currency are in theworkspace● Multiple select items in the workspace, then copy, moveor recycle as a group● Communicate your thinking or highlightvarious features of your representation using the built-inannotation tool.● Import multiple images, position and resize them●Switch between English and French
Relational Rods+ by mathies 2.0.2 APK
OAME
Represent, compare, order, and operate on whole numbers, fractionsor decimals by dragging rods from the tower into the workspace andmanipulating them.Relational Rods are rectangles of various lengthswhere each rod can be evenly subdivided by the smallest square rod.Whole Number Rods are rectangles of lengths 1 to 10 with numericlabels and dashed divisions on each rod. Decimal Rods arerectangles of lengths 0.1 to 1.0 with numeric labels and dasheddivisions on each rod. Mathematical Concepts:Create visualrepresentations that help explore mathematical thinking relatedto:• Exploring number patterns and concepts• Representing,comparing and ordering whole numbers, fractions or decimals•Composing and decomposing numbers• Skip counting forwards andbackwards• Adding, subtracting, multiplying and dividing•Proportional reasoning• Exploring rectangular areasFeatures:• Showor hide the numerical labels on the rods.• Show or hide the dashedseparations on the rods.• Set the colour of individual rods or thecolour scheme for the entire set of rods. The “traditional” paletteallows the digital tool to more closely match the colours of theconcrete manipulatives used in classrooms.• Hide some of the rodsin order to work with a restricted set.• Select a rod or set ofrods by drawing a marquee around them. Click on a rod to add orremove it from the selection.• Copy selected rods.• Rotate selectedrods.• Show or hide the background grid.• Activate or deactivateSnap to Grid mode. When active, rods snap to discrete positionsmaking it easier to align them. Deactivation allows the freeplacement of rods.• Hide/show the ruler at the bottom of the workspace.• Step through a history of your work with the undo/redobuttons.• Communicate your thinking or highlight various featuresof your representation using the built-in annotation tool.
Set Tool by mathies 2.0.4 APK
