Arithmetic Ninja for Ages 5-6 is the essential photocopiable maths resource for every Year 1 classroom from Andrew Jennings, the creator of Vocabulary Ninja, Comprehension Ninja and Write Like a Ninja.

Split into 38 weeks, this book features over 680 question cards and is fully aligned to the Key Stage 1 National Curriculum for mathematics. With activities for each day of the week plus a bonus challenge, this book is the perfect resource for daily maths practice and quick lesson starters.

The exercises in this book get progressively harder each week, and are divided into three Ninja levels to ensure differentiation. There are answers at the back to help with marking and cutting lines on each page so the activities can easily be cut out and stuck in exercise books.

Perfect for SATs preparation, the multiplication tables check and mental maths practice, this book is ideal for busy primary teachers who only want to visit the photocopier once a week. The resources are flexible and high-quality, and will ensure all pupils are maths Ninjas by the end of the year.

Arithmetic Ninja puts a fresh twist on Vocabulary Ninja with new retrieval opportunities for your classroom or home. I like the different levels so you can adapt the number sentences for the child you’re working with and there’s a school year’s worth of questions. * Tom Griffiths, Assistant Headteacher, @TJGriffiths *
Arithmetic Ninja has created a perfect way for me to allow chances to recap and embed arithmetic fluency in my classroom. Children can independently access previously learned knowledge, which allows them to explicitly practise key skills. * Emily Weston, Year 5/6 Class Teacher, @primaryteachew *
