{ "item_title" : "The Magic of the Matrix", "item_author" : [" Ian Ward "], "item_description" : "Children love magic numbers. They love to solve them and to mystify family and each other with them. This book contains various magic matrices that can be solved by children in the primary school. Most focus upon addition, with variations for decimals, fractions and some multiplication matrices. They are aimed at Grade 3 to Grade 6 children. The intention is to make mathematics and addition a positive experience by showing children how to work with the matrices and how to construct their own. A teacher or parent can also create further matrices for the children at the appropriate level.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/1/89/961/877/1899618775_b.jpg", "price_data" : { "retail_price" : "12.99", "online_price" : "12.99", "our_price" : "12.99", "club_price" : "12.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
