|Catch a Bouncing Ball - Operations|
Practise addition, subtraction, multiplication or division. For single operation games the unknown value is the result (e.g., 3 + 5 = ?). For mixed operation games the position of the unknown value changes (e.g., 3 + ? = 8). Players determine the unknown value and drag the glove to the correct answer on the number line.
Represent numbers, ratios and percents. Explore patterns and measurement. Create geometric designs. Users can change colours, create mirror images, rotate, and copy selections.
Represent various amounts using realistic images of Canadian coins and bills. Customize the money tray, drag money singly or in multiples of 2, 5, and 10, and annotate work.
Write solutions, sketch diagrams, create graphs and record your mathematical thinking. Use one of four backgrounds: grid, isometric dot, lined or blank.
Use the Rekenrek to build understanding of whole numbers, number relationships, and strategic reasoning for counting, addition, subtraction and multiplication. Relate numbers to the anchors of 5 and 10.
Represent, compare, order, and operate on whole numbers, fractions or decimals by dragging rods from the tower into the workspace and manipulating them. Rotate rods to the vertical, change rod colour and annotate work.
Additional features (v 1.1.2 June 2016):
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.
