The idea of this game is to put a dry-wipe polypropylene card into the integral cardholder on the train track and measure the length of the carriages. Children complete the answer to the question on the dry wipe card and then create trains equal in length to those featured on the card. Measure the train length by counting the windows or wheels (spaces are 1cm). There are 4 x 33cm train tracks with card holders and 12 train tracks without card holders. There are also 24 x 6cm engines and 96 carriages (1cm, 2cm, 4cm and 6cm long) in 6 colours í? red, green, yellow, blue, orange and purple. 1-4 players. Suitable for age 3 .
