Maths

Here at Highfield Hall we encourage our children to investigate and explore in maths. We use lots of concrete resources and real-life experiences to enable children to fully engage in maths and understand the concepts they encounter. This is an approach recommended by maths specialists and consultants across the globe to enable children to fully understand key underlying principles. In this way we are ensuring children learn through understanding and experience.

 

"All our experience and what we learn from research indicate that learning based on understanding is more enduring, more psychologically satisfying and more useful in practice than learning based mainly on the rehearsal of recipes and routines low in meaningfulness."  Derek Haylock and Ann Cockburn

Autumn 1

We have been learning all about numbers and what they mean. We thought about what we saw in our heads when we thought of a number and talked about what numbers mean to us. We made numbers in lots of different ways and explored how numbers are different. We explored questions such as "What does 4 mean?" and "How are 4 and 7 different?"  We chose which resources we wanted to use to show our thinking and to explore numbers further. 

After thinking about number and what they mean we were challenged to answer the question:

What is the difference between 4 and 7?

 

We use unifix to make the 5 and 7. We talked about how what we made was the same and how they were different. We could all tell our partner that one was smaller and one was bigger. Some children said that the difference between 4 and 7 was 3. They found this out by lining the two quantities up and finding that to turn the 5 into 7 they would have to add 3 more cubes. Some children said they one tower was bigger and one tower was smaller.

Singapore Bar Model

We have started learning about the bar model and how we can use this to represent addition. We used number facts we have already learnt to start thinking about how we can add parts together to make a whole! We are really good at our number bonds to 10 so we used raisins to make a bar model of number bonds to 10. We then found all the ways you can make 10 with 2 parts and wrote the numbers to show the size of each part and the whole. We did this really well and had lots of fun!

The children shared their raisins equally on their boards before sharing them with a partner.

We also use a song to help us understand the number bonds to 10. We love to sing along to Farmer Pete! If you use the link you can sing along at home too!

After making the bar model with raisins we thought about how to draw each number bond. We tried very hard to make our bars look like the correct value through their size. We found that all of our number bonds were equivalent to 10. 

After learning how we can use a bar model to represent numbers and their relationships we started looking at other part, part, whole models. We have used the circle model to show how addition and subtraction are related and have also used them to find all the ways of making number bonds up to 20. Here we are generating our own numbers, using the model to understand what we need to do and why and using cubes to calculate the addition to find the 'whole' or total.

On Pirate Day we applied what we have learnt about equals, number bonds and part-part-whole to create biscuits! Some children said, "I’m going to share ours equally so we will get 5 and 5 sweets each.” We love maths – especially when it involves food!

Autumn 2

 

We have been thinking about the history of numbers. Have they always existed? What did people do before numbers existed? Why do we use them? How difficult would it be without them? We thought about cavemen and building the best fire. How would they have known how many was ‘enough’ and used language such as fewer, more than and equal to compare amounts until we had ‘enough’. This was much harder than getting a given number of sticks. We also found that comparing could be tricky. How we lay out our sticks can change how many we think there are. We thought carefully about how we could know who had more without counting, Then we remembered ten frames. We used cavemen chalk to draw ten frames to compare quantities of sticks.

We have done lots of learning around subitising, addition, subtraction and ten frames. We have also been investigating the purpose of numbers and our number system! Today a some cavemen left us a puzzle to solve. When we arrived in school there was a mysterious box on the classroom floor. It was surrounded by sticks and leaves. We think the cavemen had left it because we have been learning about where counting and numbers began - looking at what cavemen would have done before numbers existed! We were very excited but we needed a code to open the box...it was locked!

The cavemen had left clues around our classroom. Cavemen don’t use numbers so they showed us the quantities using ten frames. We used the ten frames and our knowledge about addition to calculate which numbers might open the mysterious box. We recorded what we found.

We tried entering our numbers into the keypad on the box but it still wouldn’t open. We decided we might need a particular order so we worked together using number cards to try out various codes. It still wouldn’t work. Then we started to think the cavemen might have been logical with the order the numbers might be in. We tried sequencing the numbers from smallest to largest.

It worked! The code opened the box and we found treasure inside. We all shared the treasure. We are so pleased we could use our maths!
