Maths – This week we are learning halving

Year 1Monday We will be learning about halving objects and numbers using concrete objects and picture

representations. Adults you could ask your child what halving means to them this may give you an idea of how much your child knows about this concept.Children learn that ‘half’ means one of two equal parts and ‘whole’ means complete. Children investigate halving images and objects. They spot, describe and correct inaccuracies as they study representations of halves.

Halving means we take an object or a number and share it into two equal parts.

What does equal mean?(The same size or amount)

Let’s begin by taking a whole piece of paper and folding it in half. Can you do it another way?

Now let’s get some objects from around the house maybe some toys. Then with your adult share them equally – saying one for you and one for me. When you have shared all your objects then check to see if you have the same amount. If you do, then you could share that number of objects equally but if one person has one more then the number does not share equally. Have a go at halving some objects at home. Can you half 4 objects, 5 objects, 12 objects. Remember halving means you will have the exact same amount each. Don’t forget to send us some photos on class dojo.

Tuesday Today we are going to recap looking at halving. Vocabulary: half, halving, 2 equal parts, share, equally, the same each, sharing

Let’s make a sandwich. You will need 2 pieces of bread, butter (if you like), a sandwich filler, and a knife (may need a grown up to supervise this part).

Make your sandwich by buttering the bread (if you like butter), then spread or put in sandwich filler, then place second piece of bread on top. Now you are ready to cut your sandwich in half.Questions:How many parts has your sandwich been cut into? How do you know each piece is a half? Does it matter if they are cut in the same way? Does each part need to be the same size to be a half?Can you match the halves back together to make a whole?

Send us some photos of your halved sandwiches on class dojo.

If children have access to playdough and cutting tools, paper and scissors they could investigate making different shapes and finding ways to halve them.

We will have a go at writing ½ of ? = or half of ? =QuestionsHow many groups are we going to be sharing them into when we are halving?What will happen to the number we are halving, will it get bigger or smaller? Can you explain why?

Watch video on YouTube https://www.youtube.com/watch?v=FH0j4tUSrOg It does mention doubling because the 2 concepts are linked, but we are focusing on halving. The children need to know how to half and then be able to recall facts mentally e.g. half of 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20

We will look at reasoning when halving today. Have a look at Year One Activity – Thursday. As you work through these questions with your child/ren ask them to explain why they have answered that way. This will show a deeper understanding and that they are reasoning when answering.

Friday To finish off our week of halving we have some word problems for you. You could find objects around the home to use in a practical way to help support your halving.

For example: Mrs Kerger had made 10 cupcakes. Her family ate half of them. How many did they eat? You could draw this question out or find 10 objects. If you draw it out it would look like this.

One for you and one for me

For the answer look at one circle (one half) So my family ate 5 cupcakes.

Year One Activity – ThursdayReasoningExplain why you have answered the way you did to your adult.

Are the children correct? Colour the squares to match their labels.

Circle the odd one out Are the children correct?

Colour the shapes to match their labels.

Year One Activity – FridayEither draw it out or act it out

with objects.Send us photos on class dojo. Have fun!

1. Mrs Spencer made 12 sausage rolls. Her family ate half of them. How many did her family eat?
