Stepping Up in Math's

Today we worked on one of of Dr. Mark Biddiss' problems. An athlete trains by running up 3 steps and back 2. First we worked out how many stages it would take to climb 15 stairs then we calculated  how long it take to get to the 15th step if each 3 steps forward took 1 second and 2 steps back took 1 second. There was some great thinking and discussion involved as the children "stepped up" to the challenge!
