Year 5/6 Mastery Overview Summer Year 5/6 Mixed Year Overview Guidance Since our Year 1 to Year 6 Schemes of Learning and overviews have been released we have had lots of requests for something similar for mixed year groups. This document provides the yearly overview that schools have been requesting. We really hope you find it useful and use it alongside your own planning. The White Rose Maths Hub has produced these long term plans to support mixed year groups. The mixed year groups cover Y1/2, Y3/4 and Y5/6. These overviews are designed to support a mastery approach to teaching and learning and have been designed to support the aims and objectives of the new National Curriculum. We had a lot of people interested in working with us on this project and this document is a summary of their work so far. We would like to take this opportunity to thank everyone who has contributed their thoughts to this final document. These overviews will be accompanied by more detailed schemes linking to fluency, reasoning and problem solving. Termly assessments will be available to evaluate where the children are with their learning. If you have any feedback on any of the work that we are doing, please do not hesitate to get in touch. It is with your help and ideas that the Maths Hubs can make a difference. The overviews: • have number at their heart. A large proportion of time is spent reinforcing number to build competency. • ensure teachers stay in the required key stage and support the ideal of depth before breadth. • provide plenty of time to build reasoning and problem solving elements into the curriculum This document fits in with the White Rose Maths Hub Year 1 – 6 Mastery documents.

Year 5/6 Mixed age planning Using the document Progression documents The overviews provide guidance on the length of time that should be dedicated to each mathematical concept and the order in which we feel they should be delivered. Within the overviews there is a breakdown of objectives for each concept. This clearly highlights the age related expectations for each year group and shows where objectives can be taught together. We are aware that some teachers will teach mixed year groups that may be arranged differently to our plans (eg Y2/3). We are therefore working to create some progression documents that help teachers to see how objectives link together from Year 1 to Year 6. There are certain points where objectives are clearly separate. In these cases, classes may need to be taught discretely or incorporated through other subjects (see guidance below). Certain objectives are repeated throughout the year to encourage revisiting key concepts and applying them in different contexts. Lesson Plans As a hub, we have collated a variety of lesson plans that show how mixed year classes are taught in different ways. These highlight how mixed year classes use additional support, organise groups and structure their teaching time. All these lesson structures have their own strengths and as a teacher it is important to find a structure that works for your class. © Trinity Academy Halifax 2017 [email protected] Linking of objectives Within the overviews, the objectives are either in normal font or in bold. The objectives that are in normal font are the lower year group out of the two covered (Year 1, Year 3, Year 5). The objectives in bold are the higher year group out of the two covered (Year 2, Year 4, Year 6), Where objectives link they are placed together. If objectives do not link they are separate and therefore require discrete teaching within year groups. Year 5/6 Mixed age planning Teaching through topics Objectives split across topics Most mathematical concepts lend themselves perfectly to subjects outside of maths lessons. It is important that teachers ensure these links are in place so children deepen their understanding and apply maths across the curriculum. Within different year groups, topics have been broken down and split across different topics so children can apply key skills in different ways. Here are some examples: Statistics- using graphs in Science, collecting data in Computing, comparing statistics over time in History, drawing graphs to collect weather data in Geography. Roman Numerals- taught through the topic of Romans within History Geometry (shape and symmetry)- using shapes within tessellations when looking at Islamic art (R.E), using shapes within art (Kandinsky), symmetry within art Measurement- reading scales (science, design technology), Co-ordinates- using co-ordinates with maps in Geography. Written methods of the four operations- finding the time difference between years in History, adding or finding the difference of populations in Geography, calculating and changing recipes in food technology. Direction- Programming in ICT © Trinity Academy Halifax 2017 [email protected] Money is one of the topics that is split between other topics. It is used within addition and subtraction and also fractions. In Year 1 and 2 it is important that the coins are taught discretely however the rest of the objectives can be tied in with other number topics. Other measurement topics are also covered when using the four operations so the children can apply their skills. In Year 5 and 6, ratio has been split across a variety of topics including shape and fractions. It is important that these objectives are covered within these other topics as ratio has been removed as a discrete topic. Times tables Times tables have been placed within multiplication and division however it is important these are covered over the year to help children learn them. Year 5/6 Everyone Can Succeed More Information As a Maths Hub we believe that all students can succeed in mathematics. We don’t believe that there are individuals who can do maths and those that can’t. A positive teacher mindset and strong subject knowledge are key to student success in mathematics.
