What's included in the Inverse Operations (Addition and Subtraction) Varied Fluency resource and why is it useful?

Year 5 Inverse Operations (Addition and Subtraction) Varied Fluency is a set of worksheets during the Try it/You do section of your maths lesson. 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 a knowledge organiser for Inverse Operations (Addition and Subtraction) and 4 levelled worksheets covering adding and subtracting whole numbers with more than four digits, including using formal written methods (columnar addition and subtraction), and solving addition and subtraction multi-step problems in contexts, deciding which operations and methods to use and why.

Knowledge Organiser

• Designed to support all children via key information and examples.

Scaffolded Examples

• Finding the missing part of a bar model, then writing its related facts.

Support

• Q1: Complete a bar model to find a missing whole or part; write one addition and one subtraction.

• Q2: Finding a missing part in a worded problem; no exchange; calculation grid given.

• Q3: Find missing wholes and parts in one-step calculations; no exchanging.

Core

• Q1: Completing a bar model to find a missing whole or part; all four related facts; bar model given.

• Q2: Complete two worded problems; choose the inverse operation to find either a missing whole or a missing part.

• Q3: Find missing wholes and parts in one-step addition and subtraction calculations; unknown in different positions.

Stretch

• Q1: Completing a bar model; write four related facts; no support.

• Q2: Completing two two-step worded problems; work backwards through two operations in the correct reverse order.

• Q3: Find missing numbers in two-step calculations; undo two operations in reverse order to find missing start number.

How do our varied fluency resources work?

Our varied fluency 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 Inverse Operations (Addition and Subtraction) lesson page.

• After completing the main teaching of the Teaching PowerPoint (PPT), teachers assess whether children are ready to access their Varied Fluency worksheet or require support from the Scaffolded Examples sheet, based on how they have performed during the Model it (I do) / Practise it (We do) / Try it (You do) sequence.

• If any children need additional support, they can use the Scaffolded Examples sheet. This gives children the opportunity to secure key skills required for the Varied Fluency worksheet before they move on to it. The Scaffolded Examples sheet is designed to be completed as a group with a classroom adult.

• If children do not need the Scaffolded Examples, they can progress straight to a Varied Fluency worksheet suited to their level of understanding.

• Most children will use the Core sheet for their Varied Fluency practice.

• Some children may need the Support sheet. This is designed to be used after the Scaffolded Examples sheet, but some children might access this sheet without having used that scaffold.

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

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