Wednesday 20th Jan

Good morning. Well done with all of your lovely learning. Remember to keep going on TTR 3 times a week, for at least 10 minutes. You can do this at any point in the day, or any day of the week. 


Our starter today, will help us recap yesterday's learning. 

Our learning today, will cover how to use efficient methods to work out our multiplication problems


Being efficient means you get the answer, but with the least amount of effort and time. Now, doesn't that sound good! 


Foe example, To work out the 4 times table -

Take the number sentence  4 x 12


If we didn't know the answer we can use a simple strategy to help us.  We simply double and double again! 


Double 12 is 24                                    First double


Double 24 is 48                                    Second double


This is being efficient.


If I had to count 12 lots of 4 or 4 lots of 12, it would take me much longer and I would have to do MUCH more work to get the answer.


This is NOT being efficient.


Please watch the video and follow the instructions to complete your worksheet for your efficient multiplication. Remember, you can pause the video at any time to think about your learning, and you also can watch it again if you need to.
