"The Oxford first illustrated maths dictionary supports the curriculum and gives your child a head start in understanding first maths concepts. Organised alphabetically, this dictionary gives simple and clear meanings for over 300 maths words and concepts, from 'add' to 'zero'. Each entry is illustrated with child-friendly artwork plus diagrams, including some Numicon shapes and figures, to explain, add meaning, and support the definition. Expertly-levelled supplementary material in an illustrated section at the back lists the everyday vocabulary children will come across in their maths lessons - topics included are days of the week, months of the year, numbers, and apparatus used in class." --Publisher description.
