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.
