Last week our class was doing some problem solving. We were learning how to solve subtraction problems by using different strategies. Feel free to come and comment on my blog.
Here is one of my questions that I solved with my maths mate.
This is a strategy called Place Value
16 900 - 12 750 = ?
16 900 - 10 000 = 6900
6900 - 2000 = 4900
4900 - 700 = 4200
4200 - 50 = 4150
This strategy is called Equal Adjustments
16900-12750=?
+250 +250
17150-13000=4150
Hope you have learnt something from this.
Hi Kenny, this question sounds hard but your strategies made it easier.
ReplyDeletewow Kenny that is a hard question, good work Kenny!
ReplyDeletewow kenny that is a very hard question,I think I might try that on monday with maths problem solving.
