Number patterns and algorithms
Follow rules, complete patterns and find the first step that does not fit.
Independent Pi Leo Academy learning material organised around the Victorian Curriculum F–10 Version 2.0 Level 4 descriptors; independent curriculum review is continuing. Year 4 is not an official NAPLAN testing year; NAPLAN is held in Years 3, 5, 7 and 9. It is not an official VCAA, ACARA, NAPLAN, government or IXL resource.

follow and create algorithms involving a sequence of steps and decisions that use addition or multiplication to generate sets of numbers; identify and describe any emerging patterns
These quizzes practise concepts within this topic. Multiple-choice answers alone do not demonstrate drawing, conducting an investigation or using a digital tool.
Activities to practise beyond the quiz
- Learners follow, recognise and debug supplied algorithms; they do not independently create an algorithm in this multiple-choice profile.
- Learners recognise supplied pattern descriptions; independently written or spoken descriptions are not assessed by answer selection.
