How to introduce a child to mathematics and even make him love it? Wonderful British popularizers of science Rob Eastway and Mike Askew have found a fun and easy way to a child's heart by turning the scary bugbear - mathematics - into a series of exciting games for children from 4 years old up to 14 years old. Let your child gradually master mathematical wisdom by playing guessing games, number hide and seek, twenty and green wave every day. You can play at the table, in line at the doctor’s office, in the store, on a walk, using available counting material: cars in the parking lot, goods on supermarket shelves, motorcyclists on the road... And of course, nothing prevents you from reinterpreting the mathematical games invented by the authors in your own way , adapting them to the tastes and needs of your own children.
