Monday 15th June 2020WALT: solve subtraction problems. This week we will be revising using compact subtraction as well as how place value counters can be used to show this. We will also use the symbols < (less than), > (greater than) and = (equal to) to compare the answers to column subtraction questions. Remember, we can use counters to represent one in each column on our place value chart. So in this example, the number represented is shown below as a number sentence:

Look at this question, use what we know about addition and subtraction to work out the missing numbers. Start with the ones and think about what 8 - ? = 6, so the missing number must be 2. In the hundreds ? – 3 = 2, this must be 5. In the hundreds 3 - ? = 1, so the answer must be 2.

7000 300 80 5 = 7385

Tuesday 16th June 2020WALT: use column subtraction to solve problems.In class we have used compact column subtraction. Today you will be given a question and the answer that the person got. You must re-write the calculation to work out the answer that they got to see if they are correct or incorrect. Then, you must explain where they may have gone wrong! Remember, you can draw your own dots to represent place value counters if this helps you!

Wednesday 17th June 2020WALT: use and apply addition and subtraction skills.Last week, we looked at column addition to solve problems and this week we have been revisiting column subtraction. Use both these skills to play the game below. There are no answers as you could land on different options! If you don’t have a counter in the house, use something that you have – even make your own counter by colouring a small dot of paper. See the next slide for the game.

Thursday 18th June 2020WALT: discuss how to solve a subtraction problem.Today, you can discuss with someone at home or write some notes about how you might approach a subtraction problem.

Friday 19th June 2020WALT: solve subtraction problems.Watch the video using the following link: https://nrich.maths.org/11014(there is no sound on the video). What do you notice about the numbers that she is using and what happens when she subtracts them?

Choose some three-digit numbers of your own.(Make sure the first and third digits are different)Is there a pattern to all the answers?

Then, watch the video underneath the first video. Can you see how they have added the same number after they have subtracted and reversed the digits? Look what they all add up to in the end? Can you explain why?

HINT- a palindrome or a palindromic number is a number that reads the same forwards and backwards
