Foundation – Making 6 – 14/11/19
We have been investigating different ways to make 6. We even practised saying the corresponding number sentences, such as: 5+1=6. We also spotted that “Three twos are six, and two threes are six”. Look what we did!
Some people found that 6 can be added to 10 to make 16.
The children in Year 4 looked at column addition today and were able to use the Math Antics video to help them understand. The video took them through step by step and has allowed them to have a go and accurately answer addition questions.
Have a look at the video to help you further with your addition.
This video explains the different strategies for Year 2 addition. We recently used a few clips from this video to help demonstrate the different strategies to Palm Class and Apple Class, before applying them into our own addition learning.
It is always extremely useful for the children to see that there can be different methods which can be used in addition. They need to feel secure with their own calculation and will often be challenged to attempt to explain it in a different way, or to prove how they know they have really reached the final total.
The only difference to point out is when we partition a two digit number we are splitting the number into ‘tens’ and ‘ones’ and not ‘units’.
Which addition methods do you like to use the best and why?
We have been solving addition number problems and finding different ways to add two digit numbers. Which method do you prefer and why?
87 + 9 = ?
87 + 10 = ?
87 + 74 = ?
Which method will you choose? How will you explain your calculation? Is there another way to work it out?
Today, we have been looking at addition as part of our maths learning. We are going to be looking at all operations over he coming weeks with a focus on using formal methods. Our focus today was adding different amounts of money within a shop context.
