IfSR - Number and place value

The Interview for Student Reasoning - Number and place value (IfSR-NP) is the first of a series of on-demand assessments that enables teachers to hear and see how students apply their mathematical understandings of number and place value. IfSR-NP is divided into four sections:

  • Section 1: Understanding numbers to 10
  • Section 2: Understanding numbers to 30
  • Section 3: Understanding numbers to 120
  • Section 4: Understanding three-digit numbers and beyond

More information on each section is available below.

Assessment guide and materials

The Assessment guide and student materials document (PDF 460KB) (staff only) supports teachers to administer the assessment.

The first part of the manual outlines:

  • the purpose of the assessment;
  • details on how to prepare for, administer and lodge the assessment and;
  • a summary of related syllabus outcomes and links to the National Numeracy Learning Progression.

The second part of the manual details the materials required for each of the four sections for the assessment. Templates for printable resources are available in separate section documents below.

A complete paper version of the assessment items is also available for download if required (PDF 507KB) (staff only).

Section 1: Understanding numbers to 10

Explores the ability to recognise, read, represent, order and interpret numbers in multiple ways as well as in terms of their parts. When working towards Early Stage 1 outcomes and beyond, representing numbers in multiple ways is essential for developing number sense.

Download Section 1: Understanding numbers to 10 - materials and printable resources (PDF 1.44MB) (staff only).

Section 2: Understanding numbers to 30

Explores the ability to represent, partition, name, record, compare and order numbers, as well as use 10 as a reference in forming numbers from 11 to 20. When working towards Early Stage one outcomes and beyond, developing a sense of the size of numbers, their order and relationships is essential for developing number sense.

Section 3: Understanding numbers to 120

Explores the ability to count, order, read, represent and work flexibly with 2- and 3-digit numbers. When working towards Stage 1 outcomes and beyond, developing efficient counting strategies through an understanding of the place value pattern ‘10 of these is 1 of those’ is vital.

Section 4: Understanding 3-digit numbers and beyond

Explores the ability to apply place value to order, read, represent, partition, interpret and round numbers including decimals. When working towards Stage 2 outcomes and beyond, developing a sound understanding of the base 10 numeration system enables students to have a quantitative understanding of place value as well as rename numbers in multiple ways.
