Norah has learned to count by ones, twos, threes, fours and fives... Building on the ability to count by fives, her math curriculum is now teaching her how to figure out the minutes past the hour. She uses twelve of her five blocks to build a clock face. Then we use a nine block as a minute hand. She counts by five as far as she can, then counts by one until she figures out the answer, just like we grown ups do when we when need to find out how many minutes have past the hour. I wish I had been taught to understand a clock's face this way! My daughter is five and she is telling time!
