A maths book like no other, based on a song about the maths children use every day when they play, share, bake, do sport or make music.
"The world would be a better place if Mr Smith was everyone's maths teacher! Here’s your chance to join him on a fabulously entertaining journey exploring how each of us is using Maths all the time.’’ - Bobby Seagull, mathematician, broadcaster and author
THAT'S MATHEMATICS is a vibrant, colourful picture book for 5 to 8 year olds, showing them that maths is useful, interesting, fun and EVERYWHERE! We use it every day without even realising.
Young children can enjoy Tom Lehrer's rhyming song and Elīna Brasliņa's bright and busy illustrations, picking up a basic understanding of real-world maths and some early maths language. Older children are challenged by 'Try This' and 'Explore This' activities written by Chris Smith, a maths teacher, musician and all-round maths enthusiast. The activities are designed to deepen their curiosity and knowledge.
There are also supporting online activities, notes for parents to encourage you to get involved and keep the learning going after the book is closed, and a glossary of maths terms too!
Brilliant for early years, home learning, and a useful and fun book to support the primary maths curriculum KS1.
