Set of 36 cards includes a key card, 26 letter cards and 9 number cards. Measures approximately 78 x 108mm. Each letter card features a dinosaur starting with each letter of the alphabet and the letter in both upper and lower case. Flip the card over for a full dinosaur illustration, dinosaur name, pronunciation, and a fun fact. Use the key card to colour match each card to show what era the dinosaur lived.  The number cards work in the same manner but provide some counting fun. A great addition to our Alphabet of Amazing Dinosaur Colouring Book.
