multiply and divide by one-digit numbers using repeated addition, equal grouping, arrays, and partitioning to support a variety of calculation strategies

How Bloomi helps with this

This is a readiness-year topic that builds towards the next NAPLAN year. Bloomi practises it as curriculum mastery, never test drilling.

What this looks like in the classroom

• making and naming arrays and using bar models to solve simple multiplication or sharing problems; for example, make different arrays to represent \(12\) and name them as “\(3\) fours”, “\(2\) sixes”, “\(4\) threes”, “\(6\) twos”; using physical or virtual materials to make arrays or using bar models to demonstrate that “\(3\) fours” is equal to “\(4\) threes”
• finding the total number represented in an array by partitioning the array using subitising and number facts; for example, describing how they determined the total number of dots arranged in a “\(3\) fives” array by saying “I saw \(2\) fives which is \(10\) and then \(5\) more which makes \(15\)”
• recognising problems that can be solved using division and identifying the difference between dividing a set of objects into \(3\) equal groups and dividing the same set of objects into groups of \(3\)
