Introducing sophisticated mathematical ideas like fractals and infinity, these hands-on activity books
present concepts to children using interactive and comprehensible methods. With intriguing projects that
cover a wide range of math content and skills, these are ideal resources for elementary school
mathematics enrichment programs, regular classroom instruction, and home-school programs.
Reproducible activity sheets lead students through a process of engaged inquiry with plenty of helpful tips
along the way. A list of useful terms specific to each activity encourages teachers and parents to
introduce students to the vocabulary of math. This second Big Ideas book covers more advanced
concepts, with projects including “One in a Million,” where children use grains of rice to model the
probability of astronomical odds; “Triangular Tessellations,” in which students investigate the geometry
and variations created by repeating patterns; and “Fractions of Salaries,” where kids use a real-world
scenario to multiply and divide fractions.
