As mathematicians we have been adding ones to 4 digit numbers

Sunday 20 October 2024

This week Year 4 have started a new unit in maths with a focus on addition and subtraction.

We started the learning by practising adding between one and nine to a number.  We started with 2 digit numbers and worked up to 4 digit numbers. We showed great teamwork with our partner when using double sided counters and place value charts to look for a pattern.

We noticed that the digit in the ones column always changes, the digit in the tens column sometimes changes and the digit in the hundreds column sometimes changes.

We will be moving on to formal methods of addition and subtraction (often called column method) but it is really important that we all notice when there are calculations that we can do in our head.  Looking for patterns and being able to imagine the numbers will help all of our amazing mathematicians to calculate efficiently.

Help at home: If you would like to consolidate this learning at home you could watch the video from White Rose Maths with your child: https://vimeo.com/729667222

You could also challenge your child by choosing a 4 digit number and asking them to add between 1 and 9 to the number.  The children are really good at spotting the tricky ones where they will need to exchange.  If you want to make it more like a game why not try this random number generator (https://numbergenerator.org/random-4-digit-number-generator) and challenge your child to do as many examples as they can in a minute.  Can they score higher than you?
