NUMBERS
You can’t do math without numbers. There are 10 number symbols, but they
can be used to write or count as many numbers as you can imagine. In this
chapter, you’ll find projects that will help you understand numbers, from
making your own fridge magnets to using the power of fractions to divide a
pizza fairly. You’ll also make an abacus to help you master complex
calculations and a dreamcatcher that will test your times tables.

FAMILY MATH CHALLENGE
NUMBER FRIDGE
MAGNETS
With some adhesive magnetic sheets and colored card stock, you can make
your very own number magnets. Use them to set challenges for your family
on the fridge and see who will be the first to figure out the answers to
your fiendish questions.
