"The Stack Model Method: An Intuitive and Creative Approach to Solving Word Problems (Primary 5-6)" is the second title of a two-book series in Singapore maths publishing, which comprehensively reveals the beauty and power of the stack model method as an intuitive and creative problem-solving strategy in solving non-routine questions and challenging word problems. Like the Singapore's bar model method, the stack model method allows word problems that were traditionally read in higher grades to be set in lower grades. The stack model method empowers younger readers with the higher-order thinking skills needed to solve word problems much earlier than they would normally acquire in school. Singapore's stack model method is a more creative and intuitive visualisation problem-solving strategy than the bar model method. Brain-unfriendly word problems that are bar-model-unfriendly tend to lend themselves easily to the stack model method. Features of this Singapore maths playbook are: * Look-See Proofs for Kids * Visible Thinking in Mathematics * Advanced Visual Literacy * Creative and Higher-Order Thinking Skills * Alternative Solutions and Thought Processes The Stack Model Method would benefit all primary 5-6 pupils, teachers and parents, as they acquaint themselves with this visualisation problem-solving strategy to solve both routine and non-routine questions, while indirectly helping them to enhance their creative thinking and problem-solving skills in mathematics. Learn what the best primary 5-6 pupils in Singapore do in primary school mathematics - you too can learn to solve the types of challenging questions they deal with every day in local schools and tuition centres island-wide.
