{"product_id":"first-mental-arithmetic-book-4-book-ann-montague-smith-9780721711669","title":"First Mental Arithmetic Book 4","description":"First Mental Arithmetic provides carefully graded questions that develop children's essential mathematics skills. A downwards extension of the Schofield \u0026amp; Sims bestseller Mental Arithmetic, the series comprises three workbooks for Year 1 (Books 1 to 3) and three for Year 2 (Books 4 to 6). The term 'mental arithmetic' is usually associated with spoken questions. However, children using all the Schofield and Sims Mental Arithmetic materials read the questions themselves and write down their answers. A Language of Maths glossary helps to develop children's number vocabulary and three Check-ups assess children's understanding. The separate First Mental Arithmetic Answers provides answers to all questions contained in this book, plus additional resources for teachers.  Book 4 includes: reading and writing two digit numbers, multiplication and division, halves, quarters and three-quarters, sorting objects, measuring lengths and reading scales.","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":49513153134865,"sku":"GOR004475671","price":10.3,"currency_code":"USD","in_stock":true},{"title":"GB \/ GOOD \/ INTERNAL","offer_id":49726922391825,"sku":"GOR006528622","price":10.3,"currency_code":"USD","in_stock":true},{"title":"GB \/ NEW \/ GARDNERS","offer_id":49728966689041,"sku":"NGR9780721711669","price":11.39,"currency_code":"USD","in_stock":true},{"title":"GB \/ WELL_READ \/ INTERNAL","offer_id":49894157779217,"sku":"GOR009558622","price":10.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0721711669.jpg?v=1751426492","url":"https:\/\/www.worldofbooks.com\/products\/first-mental-arithmetic-book-4-book-ann-montague-smith-9780721711669","provider":"World of Books ","version":"1.0","type":"link"}
