This book and accompanying CD-Rom focuses on the use of open-ended questions in the maths classroom. Open-ended questions promote effective problem-solving skills and can be easily incorporated with thinking tools such as Bloom's Taxonomy, Multiple Intelligences, Habits of Mind, Creative and Critical Thinking and other organisational skills. These tried and tested, ready-to-use and reproducible task cards can be used throughout the primary maths classroom. The topics, covering measurement and number, address curriculum content for each of the levels covered from junior to upper primary. Tasks have been developed to encourage critical thinking at one of the 6 levels of Bloom's Taxonomy.
