Multi-Step Word Problems - Subtraction
This PowerPoint contains 20 real-world subtraction-based word problems presented in multi-step format to develop students’ reasoning, problem-solving, and fluency with subtraction. Each question builds gradually in complexity across three related prompts, with answers provided after each problem. Suitable for classroom modelling, group problem-solving, or individual practice.

Learning goals
- We are learning to multiply and divide one- and two-digit numbers in word problems using a variety of strategies.
- We are learning to estimate the quantity of objects in collections and when solving problems.
- We are learning to count in fractions on a number line, represent and locate fractions on number lines and convert mixed numerals into improper fractions and vice versa.
- We are learning to use a range of strategies to solve addition, subtraction, multiplication and division where there is no remainder.
- We are learning to recognise that 100% represents a whole and use percentages to describe, represent and compare relative percentages visually, e.g. shading a hundreds grid and connect percentages to their decimal and fraction equivalents.
- We are learning to solve problems involving multiplication of large numbers by 1- or 2-digit numbers using efficient mental or written strategies and appropriate digital technologies, e.g. arrays.
- We are learning to apply knowledge of place value to add and subtract decimals and to use estimation and rounding to check the reasonableness of our answers.
- We are learning to multiply and divide decimals by multiples of powers of 10 using our knowledge of place value and multiplication facts (times tables), to estimate and check answers.
- We are learning to recall multiplication facts of two, three, five and ten and related division facts.
- We are learning to use estimation and rounding to check the reasonableness of answers to calculations.
- We are learning to count by quarters, halves and thirds, and convert fractions and locate and show fractions on a number line.
- We are learning to use a range of strategies to solve multiplication and division where there is no remainder.
- We are learning to solve word problems by using number sentences involving multiplication or division where there is no remainder.
- We are learning to make connections between equivalent fractions, decimals and percentages.
- We are learning to solve problems involving multiplication of large numbers by one or two-digit numbers using efficient mental or written strategies and appropriate digital technologies, e.g. area model, arrays and Italian Lattice Method.
- We are learning to add and subtract decimals and use estimation and rounding to check answers.
- We are learning to multiply and divide decimals by powers of 10.
- We are learning to multiply and divide decimals by whole numbers where the results are terminating decimals.
