"A wonderful collection of attractive math topics that will entertain and inform kids (and their parents). A great way to share a stimulating learning activity." - Ronald L. Graham, Professor in Computer Science and Engineering at the University of California, San Diego, former Mathematical Association of America president, former American Mathematical Society president, former Bell Labs Chief Scientist "This compilation of fresh, hands-on STEM activities explores a variety of mathematical concepts, from basic geometric shapes to parabolas, fractals, and puzzles...Recommended for libraries and educators seeking a tactile approach to elementary mathematics." - Doneanne Soult, Westampton Middle School, NJ, for School Library Journal "Required materials are all readily available: in the opening pages, children can use gumdrops and toothpicks like Tinkertoys to build cubes, pyramids, and other three-dimensional structures; many projects need nothing more than pencil and paper. Removable paper templates are provided for some of the activities. Rapaport and Yoder make the projects accessible to readers of varying skill levels, whether they are learning about basic shapes or developing a more advanced understanding of mathematics." - Publishers Weekly "Five thematic chapters define broad types of applications, such as curves and fractals, graph theory, and topology. This collection of activities celebrates an inquiry-based approach to learning math, which may be an excellent complement to more traditional classroom curricula, especially for reluctant learners. As such, it's a great resource for parents, teachers, and curious young readers alike." - Erin Anderson, Booklist Online 'With more than 50 activities inside, there's so much to do, whether it's making prisms and pyramids or building your own toothpick puzzles.' * How It Works *
