Here is everything you will need to run a KS1 maths challenge in your school. All 15 challenge are based on mental arithmetic and number facts. There are 15 levels to the challenge - which are called 'missions' and for each, there is an accompanying homework sheet which details their mission and the 'reward. The first reward is to earn their meteor proof space suit, and others include gravity defying space boots, gadget belt and a multi coloured laser (all virtual rewards of course, but fun to collect!). The whole class then has a timed challenge to complete the sheet for whatever mission they are on. The challenge has been designed to meet the increased requirements of the 2014 National Curriculum and support preparation for KS1 SAT's. This mega resource comes with instructions, 15 homework sheets, 15 challenge sheets, a set of stickers for the children for their achievement for each mission, display pictures, a cover for the folder to keep all the resources organised, an information letter for parents and a list of all of the missions and their learning objectives. This FREE version is the result of many hours of preparation and is completely usable as it is. In my shop you can also purchase a paid version which is fully editable to enable you to adapt or personalise all of the resources. You could also create some additional challenges if you wanted to extend this into KS2. It also includes additional stickers for the children's books detailing the 'I can' that they have achieved to support assessment. Please note that sticker sheets have been made to fit Consortium 65 labels. Feedback welcome, enjoy!
