Our grade 3 and 4 classes at Nanjing International School (China) are currently studying estimation and body benchmarks in maths. In PE we are doing a unit on Adventure Challenge. In today's class I divided the class up on to 4 teams. The were presented with the following 4 challenges:
How many legs will it take to cross the width of the gym?
How many elbow to finger tips will it take to cross the length of a badminton court?
How many arm pits to feet will it take to cross the length of the gym?
How many heads will it take to cross the width of the badminton court?
At first, they had to estimate the number of body parts from point A to point B, then estimate the number of meters from point A to point B. Next they completed the task on their teams (actually stretching themselves out across the floor connecting the required body parts among their team members). Thirdly, they had to record the actual number of body parts it took. Lastly, they had to record the actual distance in meters (which I gave them after completing each task) and then figure out, through mental maths, how far off they were from their originally estimated number of body parts. For example, if a student recorded that they thought the number of legs to cross the width of the court was 21 legs and the actual number was 17 legs, they were 4 legs off their original estimate. They would record 4 legs in the last column of the record sheet.
The record sheets were given to the classroom teacher who will now use the recorded data in their next maths lesson. In my opinion, authentic and genuine links were made to maths in this lesson. Try it out!!! Please see pictures of the slide show below to see student record sheets and pictures of the kids in action.
