GEO Koalas
Mass Comparison, Size-grading, weighing, counting, sorting, and patterning.
These lovely plastic koalas in three sizes (Papa koala 45mm, Mama koala 35mm and Baby koala 30mm) and four colours will motivate children to learn colour, sorting, patterning, measurement, sequencing, number sense and more.
TEN-FRAME CARRIAGES
A ‘seriously fun’ counting and number recognition strategy. The ability to visualise numbers -named 'subitising'- is an important skill that children in the Prep room ought to acquire. Our 10's frames are a powerful instrument to assist pupils in developing such strong visual memory of numbers and number sense once they have acquired basic notions of counting. Ten's frames help to bring about a more sophisticated counting technique as they favour the recognition of numbers from 1 to 10 and of the relationships among said figures.
GEO koala carriages with ten seats for small koalas will replace the usual mats and drawn paper cut-outs to make this number exploration MORE EXCITING! Especially by repeatedly placing the koala counters into the top-row seats first (left to right) and then filling the bottom-row seats (also left to right), pupils will develop sight recognition of number patterns. When they can immediately see 5 and 10 koalas in the ten-frame bus, they can count on or back from these numbers to find the amounts.

KOALA SUDOKU KITS
Sudoku, sometimes spelt Su Doku, is a Japanese logic-based placement puzzle, also known as Number Place in the United States. Its aim is to enter a cypher from 1 to 9 in each cell of a 9×9 grid made up of 3×3 sub-grids (called "regions"), starting with various digits given in some cells (the "givens"). Each row, column, and region must contain only one instance of each cypher. We replaced numerals with GEO koalas differentiated by colour.
