Your students can follow your every move with their own double-sided clock card. This larger-than-normal card is very easy for young hands to use. The hour number boxes tell the student which hour number to read at any point in time and 1/4 hour markings for the hour hand help them place the hands in the correct positions relative to each other. The 5-minute numbers are highlighted and all the minute numbers are shown. The hands tell your students which numbers to read, or help them dial the time that you suggest. 15cm x 20cm. Dial 13.5cm. Made from super-tough polypropylene these cards will last for years. They come in boxes of 10 or 30 for easy storage. They are also available singly.
