What's included in the Subtract Two 4-Digit Numbers - No Exchange Reasoning and Problem Solving resource and why is it useful?

Year 4 Subtract Two 4-Digit Numbers - No Exchange Reasoning and Problem Solving is a set of 3 worksheets designed to be used during the independent reasoning and problem solving section of your maths lesson. Once children are secure in varied fluency, they are ready for these worksheets.

Each set has been carefully designed to help you meet each child where they are at to ensure progress for every child, not just the average child. The content includes 3 levels of content (Support, Core and Stretch) for Subtract Two 4-Digit Numbers - No Exchange covering subtracting numbers with up to four digits using the formal written methods of columnar subtraction where appropriate, and solving subtraction two-step problems in contexts, deciding which operations and methods to use and why.

Support

• Q1: Reasoning - judging a character’s statement about subtracting with place value counters, with the first number shown in counters.

• Q2: Reasoning - explaining whether a worked column subtraction is correct, with the first number shown in counters and a tip.

• Q3: Problem Solving - arranging four given digits to make a number to subtract from a given 4-digit number shown in counters, with no exchange.

Core

• Q1: Reasoning - judging a character’s statement about subtracting with place value counters.

• Q2: Reasoning - explaining whether a worked column subtraction with a 3-digit number or a zero placeholder is correct.

• Q3: Problem Solving - arranging eight given digits into two 4-digit numbers so that a subtraction needs no exchange.

Stretch

• Q1: Reasoning - judging a character’s statement about subtracting a 3-digit number with place value counters.

• Q2: Reasoning - checking a worked answer given in linear form by completing the column subtraction, including a 3-digit number, where the error involves a zero placeholder or the thousands digit.

• Q3: Problem Solving - arranging eight given digits into a subtraction with no exchange whose answer meets a condition.

How do our reasoning and problem solving resources work?

Our reasoning and problem solving resources are not just about differentiation, but differentiation in an adaptive way. They work best alongside our teaching PowerPoints, which walk you through the whole lesson along with other lesson resources that you can find on our Subtract Two 4-Digit Numbers - No Exchange lesson page.

• After completing the Varied Fluency worksheet, children are now ready for their Reasoning and Problem Solving work.

• Most children will use the Core sheet for their Reasoning and Problem Solving practice.

• Some children may need the Support sheet. This has been included to give specific children the additional support required to develop their reasoning and problem solving skills and access the core content.

• Some children may need additional challenge; the Stretch sheet will deepen their understanding of the core content.

• Within the Teaching PowerPoint, a question similar to what is presented in question 1 on these sheets is given, alongside sentence stems. This can be used to lead discussion on how to solve question 1 and give all children ideas on what reasoning can be used, via oracy, to tackle the question.

Adaptive Maths Resources are not a separate lower-attainment route. They provide temporary and responsive support to help pupils access the same intended learning.
