Last week I asked you to do some addition using the column method. This week I want you to focus only on taking away.
Some of you may have done your MyMaths task already. If you didn’t score above 70%, remember you need to do it again if you want to win two merits. Watch my video and then try your MyMaths again, or try the activities below the video.
I recorded this video before my surgery.
It’s very important you practise the column method for subtraction, as it takes some getting used to. Here are some more questions you can complete. Send your answers to email@example.com to win another merit.
The first page does not include any regrouping, so I’m sure even my Maths Group can have a go at it without too much trouble! Just remember to use columns. Please go to Page 3 for the regrouping problems (on the sheet regrouping is called ‘exchanging’).
Look at my tower from the beginning of the video.
If the tower was 1 bottle high, there would be 1 bottle.
If the tower was 2 bottles high, there would be 3 bottles.
If the tower was 3 bottles high, there would be 6 bottles.
If the tower was 4 bottles high, there would be 10 bottles.
If the tower was 5 bottles high…
If the tower was 6 bottles high…
In the comments, keep going as far as you can go with this pattern. What pattern can you see? Explain it.
