We bought Lucas a stopwatch for Christmas and WOW what an education tool!!
In two days I have timed him countless amount of times around the house on the bike track, up and back of the pool in various swiming styles and Mollie has been timed doing many different tasks around the house.
In the two days, he has understood the concept of timing, able to put all in times in correct order from fastest to slowest and compared the times ie which is faster 1 lap around the house on his bike or 1 lap in the pool.
Lots of great timing fun!!!
