Everyone welcome! # Year 4 - Maths: Subtraction ![](https://files.schudio.com/st-barnabas-primary-school/images/news/IMG_2607.jpeg) 6 November 2024 Our place value grids are coming in very useful in maths this week. We’ve been learning how to subtract two 4-digit numbers, working up to making exchanges. In order to understand the concept of exchanges, we drew out the problem and crossed off the counters. Then we could see if there wasn’t enough to take from a column and adjusted accordingly. We will continue to develop this technique across the week. ![](https://stbarnabasdarwen.co.uk/images/news/IMG_2607.jpeg) [Year 4](https://stbarnabasdarwen.co.uk/news/tag/year-4) [Maths](https://stbarnabasdarwen.co.uk/news/tag/maths) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/IMG_5624.jpeg)](https://stbarnabasdarwen.co.uk/news/2024-11-05-edstart-jag-tag-festival) Previous ### [Edstart Jag Tag Festival ](https://stbarnabasdarwen.co.uk/news/2024-11-05-edstart-jag-tag-festival) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/IMG_4796.jpg)](https://stbarnabasdarwen.co.uk/news/2024-11-07-reception-visiting-our-spiritual-garden) Next ### [Reception: Visiting our Spiritual Garden](https://stbarnabasdarwen.co.uk/news/2024-11-07-reception-visiting-our-spiritual-garden) ### Personal Development - [News](https://stbarnabasdarwen.co.uk/news) - [Events](https://stbarnabasdarwen.co.uk/events) - [Photo Gallery](https://stbarnabasdarwen.co.uk/photo-gallery-category/our-gallery) - [Calendar](https://stbarnabasdarwen.co.uk/calendar) - [School Council](https://stbarnabasdarwen.co.uk/academy-life/school-council) - [Attendance](https://stbarnabasdarwen.co.uk/academy-life/attendance) - [Fundraising](https://stbarnabasdarwen.co.uk/academy-life/fundraising) - [Extra Curricular Clubs](https://stbarnabasdarwen.co.uk/academy-life/clubs) - [Little Leaders](https://stbarnabasdarwen.co.uk/academy-life/little-leaders) - [Visits and Visitors](https://stbarnabasdarwen.co.uk/visits-and-visitors) - [British Values](https://stbarnabasdarwen.co.uk/british-values) - [Protected Characteristics](https://stbarnabasdarwen.co.uk/protected-characteristics) ##### Location Knowlesly Road Darwen Lancashire BB3 2JA ##### Contact Us 01254 702996 ##### Stay Connected - [Facebook](https://www.facebook.com/stbarnabasce/) - [X](https://twitter.com/stbarnabasce) © Copyright 2021–2026 St Barnabas Primary School, A Church of England Academy School & Trust Websites by [ ![Schudio logo](https://stbarnabasdarwen.co.uk/img/logo/light.png) ](https://www.schudio.com/)
