Look at the numbers below, quickly pick out the multiples of 10. Today your multiples of ten are going to help you subtract across the tens boundary (a multiple of ten e.g. when we count back from 43, 42, 41,40, 29, 28 we count past the ten boundary of 40)
Today we are going to carry on with our subtraction, again using a number line, but this time we will be tackling calculations that cross over the tens boundary when we are subtracting the ones. Calculations like this; 73 - 27 = or 64 - 38 =
When we do these will still subtract the tens as normal but then when we subtract the ones we first jump down to the multiple of ten first and ten subtract the rest of the ones.
The reason we do this is because when we are counting backwards across the tens boundary mistakes can sometimes be made. Take a look at the example below.
Can you see that when I subtracted the 7 ones I split it into a jump of -3 which took me to the nearest multiple of 10, 50 but I need to take away 7 ones so I subtract another 4.
*****Children will find this tricky if they are unsure of their quick addition and subtract facts so may need to count down in ones shown on the diagram below.*****
Let's go through another example step by step. First I take away the 3 tens.
Now I'm going to take a jump the multiple ten below 34 which is 30.
So far I have taken away 4 to get to the multiple of ten, 30. But I need to take away 8 so I take away a further 4 to make a total of 8.
This method helps you to practise bonds to ten, quick addition and subtraction facts as well as being a method for subtracting large numbers.
Persevere today because it can be tricky, but have a go at showing your workings on an empty number line. If you find it really difficult have a go with the numbered number lines below.
Today I would like you to log on to Phonics Bug, not everybody has yet, so I just want to make sure you all know it is there and you can all log on as well. There are reading books and quizzes on there but also lots of fun games and activities. If you are unsure of your username or password please contact the school office.
Topic/ - Geography
Well done to everyone who sent in their last piece of Geography looking at the difference between a village, town and city. Today we are going to continue our learning. Read the speech bubbles below and decide if you think the people live in a village, town or city. What has helped you make your decision? You might need to discuss your ideas with an adult at home. You don't have to write a reason for the speech bubbles because there are lots to sort but try to explain your thinking as you sort them. There are some sorting labels included in the print out.
I think this person lives in a city because they mention office buildings and tall building and they are usually in cities. Also I know that many people travel into cities to work.
I think this person lives in a village because villages often have only one shop because fewer people live and shop there. Things are more expensive because they are more difficult to get.
You can print them out and cut them up to sort. If you don't have a printer read them through and decide if they are village, town or city.
