||
 * Early Stage One **
 * //**NES1.3: Groups, shares and counts collections of objects, describes using everyday language and records using informal methods.**//


 * Key ideas:**
 * Model equal groups or rows
 * Group and share collections of objects equally
 * Record grouping and sharing informally ||


 * Stage One ** ||
 * //**NS1.3: Uses a range of mental strategies and concrete materials for multiplication and division.**//


 * Key ideas:**
 * Rhythmic and skip count by ones, twos, fives and tens
 * Model and use strategies for multiplication including arrays, equal groups and repeated addition
 * Model and use strategies for division including sharing, arrays and repeated subtraction
 * Record using drawings, numerals, symbols and words ||

||
 * Stage Two **
 * //**NS2.3: Uses mental and informal written strategies for multiplication and division**//


 * Key ideas:**
 * Develop mental facility for number facts up to 10 x 10
 * Find multiples and squares of numbers
 * Interpret remainders in division problems
 * Determine factors for a given number
 * Use mental and informal written strategies for multiplying or dividing a two-digit number by a one-digit operator ||

||
 * Stage Three **
 * //**NS3.3: Selects and applies appropriate strategies for multiplication and division.**//


 * Key ideas:**
 * Select and apply appropriate mental, written or calculator strategies for multiplication and division
 * Explore prime and composite numbers
 * Use formal written algorithms for multiplication (limit operators to two-digit numbers) and division (limit operators to single digits) ||
