W5T2 | Maths Strategy

Last week for maths I learnt how to do rounding and compensating which is an easy strategy to solve multiplication problems! So, for example if you want to figure out what 6 x 21 is then all you have to do is 6 x 20 ( rounding it to the nearest 10 ) which is 120 because 6 x 2 is 12 and then just add a zero to it which is 120! Then, 6 x 1 to add to 6 x 20 to make 6 x 21 which is 6 then add them together - 120 + 6 = 126! And there's your answer, 6 x 21 = 126! - (6 x 20) + (6 x 1)    

                                                           120             6

                                                           120 + 6 = 126 

                                                  and there's your answer!

It is a very easy and quick strategy to do, it is also very helpful when solving multiplication problems with big numbers. I enjoyed learning and using this strategy because it makes it easier to solve multiplication problems!
