Visible Thinking in Mathematics is a series of eleven supplementary books that promotes critical and creative thinking in mathematics. It is designed to help make thinking visible by providing the child with opportunities to think, explore and reflect.
While practice leads to better performance, practice without contextual and conceptual understanding prevents the child from thinking critically and creatively. In this series, instead of learning procedures and formulas by rote, the child masters concepts through:
 Thinking routines: functional questions to direct the child's thinking on key concepts and cultivate the child's thinking skills.
 Parallel questions: consecutive mathematical problems with the same context but different key words to highlight differences between problems; ensuring that the child understands and retains concepts and skills better.
This approach not only instills in the child mathematical skills but also inspires discipline in thinking and greater motivation for learning.
Additional support is provided to the child through Notes. Notes present opportunities for parents and teachers to clarify misconceptions, simplify difficult concepts and address areas of difficulty for the child.

Our recommendation:
This is a good supplementary series for reteaching students who need additional guidance. The books emphasize the pictorial stage and helping students to move from the pictorial stage to the abstract or contextual stage. They include questions the teacher can ask the student to get them to think about the concepts, as well as teaching tips for the teacher that include common errors.
They would be useful in the classroom for teachers as a differentiation tool to use when working with students who need additional help, or for homeschoolers whose students need additional practice, discussion, and visual aids before moving to the abstract stage or before doing some of the more challenging material.
Includes some model drawing sooner than appropriate, as well as recording steps for strategies that would normally be a mental math strategy for more capable students, but this can be useful for those students who need more guidance through those particular strategies. It should not be used as a substitute for the Primary Mathematics, particularly for more capable students, but rather as a reteaching tool. There are detailed answers in the back.
