Based on the PCNs - National Curriculum Parameters - and supported by authors who discuss the subject, as well as areas of knowledge associated with Maths Education, we will address the need to create mechanisms for students to acquire knowledge and reasoning. Finally, the aim of this work is to shed light on the relevance of using technology, with a view to maths that is little used in the classroom.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/6/20/880/730/6208807301_b.jpg", "price_data" : { "retail_price" : "39.00", "online_price" : "39.00", "our_price" : "39.00", "club_price" : "39.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
