Happy Investigation day!
The work today will not be quick, if you do it properly, you will need to be working out lots of squared numbers and seeing if they fit your task. Please do persevere with this task as you have ALL shown that you have great knowledge of your times tables and also squared numbers!
Take your time and watch the videos to get you started :)
I do appreciate that there are lots of videos but please just watch one of the refresher videos (if needed), the shorter method is slightly trickier so bare that in mind. Then please watch your level of challenge video for a starting point :)
Please do watch the video on long multiplication - this will help you work out your squared numbers.
DO MAKE A BANK OF YOUR SQUARED NUMBERS ON A SHEET OF PAPER, THIS WILL MAKE THE TASK A LOT EASIER!
1 x 1 = 1
2 x 2 = 4
3 x 3 = 9 etc.
