## Foundation Statement strands

*The following strands are covered in this activity:*

## Description of activity

- Students are presented with the scenario: ‘The answer is 12. What could the question be?’
- They are asked to record a variety of questions, including number sentences and word problems.
- Students are asked to ensure that they use each of the operations: addition, subtraction, multiplication and division.
- They are also asked to include different types of numbers (whole numbers up to four digits, fractions, decimals).

The suggested time allocation for this activity is 20 minutes.

## Suggested materials

Paper, pencils/pens

## Prior learning

Students have used concrete materials, mental strategies and informal written strategies for addition, subtraction, multiplication and division. They have used formal written algorithms and have applied place value to solve addition and subtraction problems. Students have compared and represented fractions with denominators 2, 4 and 8, and 5, 10 and 100, and decimals to two decimal places. They have asked questions that could be explored using mathematics in relation to Stage 2 content.

## Outcomes

**Addition and Subtraction (NS2.2)**

Uses mental and written strategies for addition and subtraction involving two-, three- and four-digit numbers.

**Fractions and Decimals (NS2.4)**

Models, compares and represents commonly used fractions and decimals, adds and subtracts decimals to two decimal places, and interprets everyday percentages.

**Multiplication and Division (NS2.3)**

Uses mental and informal written strategies for multiplication and division.

**Questioning (WMS2.1)**

Asks questions that could be explored using mathematics in relation to Stage 2 content.

**Applying Strategies (WMS2.2)**

Selects and uses appropriate mental or written strategies, or technology, to solve problems.

**Communicating (WMS2.3)**

Uses appropriate terminology to describe, and symbols to represent, mathematical ideas.

## Criteria for assessing learning

Students will be assessed on their ability to:

- construct a variety of mathematical problems using different operations
- demonstrate number relationships using the four operations and whole numbers, fractions and decimals.
