Time Difference

 I learnt how to count time difference. Difference in maths means subtract. Difference can be found bewteen two things. 

I first started subtracting time. The time was 4:05. 

then I added forty minutes and four hours and it gave me 8:40.  

I then wrote in my total. My total was four hours and forty minutes differece. 

I enjoyed this task because I learnt a subtraction stratagy.
