LI: How to calculate cubes and cube roots of numbers.

In maths, my group created a DLO about cubes and cube roots. We learned that cubing a number means multiplying it by itself three times, and a cube root is finding the number that was multiplied to make the cube number. For example, 3×3×3=273 \times 3 \times 3 = 273×3×3=27, so the cube root of 27 is 3. While making our DLO, we used examples and diagrams to help explain our thinking clearly. It was interesting learning how cube numbers connect to the edge lengths of cubes and how maths can be shown visually as well as with numbers. This task helped me understand cubes and cube roots more confidently. It also helped me practise explaining maths ideas in a simple and organised way while working together as a group.

In maths, my group created a DLO about algorithm addition with decimals. We learned how to line numbers up correctly using place value and decimal points so the equation stays accurate. We also learned that adding a zero as a placeholder can help make decimals easier to solve.

In our example, we added 51.40, 80.60, and 38.75 together using the vertical algorithm method. First, we lined up the decimal points and place values carefully. Then we added each column one at a time, starting from the right. When the total was more than 10, we carried the extra number to the next column. Our final answer was 169.75. This activity helped me understand how important place value is when working with decimals. It also helped me become more confident solving decimal equations and explaining my maths thinking clearly.

LI: To understand how to identify and round significant figures.

This week in maths, My group has been learning about significant figures. These are the digits in a number that show how accurate it is. I learned how to identify which numbers count, especially when zeros are involved, as they can sometimes be tricky depending on where they are in the number. We also practised rounding numbers to a certain number of significant figures. To do this, I had to look at the next digit and decide whether to round up or keep it the same. At first, it was a bit confusing, but after practising, I started to understand the patterns and rules more clearly. This learning helped me improve my accuracy when working with numbers and made me more confident in rounding and identifying significant figures.

LI: To understand how to identify the highest common factor.

In maths, we have been learning about highest common factors (HCF). This is the largest number that can divide into two or more numbers without leaving a remainder. To work this out, I found all the factors of each number and then compared them to see which one was the highest they both shared. At first, it was a bit challenging to keep track of all the factors, but as I practised more, I started to notice patterns and became quicker at solving the problems. This helped me understand how numbers are connected and how it works. I now feel more confident finding the HCF and explaining my thinking clearly.

LI: How to identify Prime and Composite numbers.

This week in maths, my group and I learned about prime and composite numbers. We practiced how to tell if a number is prime, which only has two factors, or composite, which has more than two. We looked at examples like 43, which is prime because it can only be divided by 1 and itself, and 60, which is composite because it can be divided by many numbers like 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30. Doing this helped me understand how numbers are made and see patterns in their factors. I also feel more confident now in recognising whether numbers are prime or composite, which will help me in future maths problems.

LI: Understanding how to identify the lowest common multiple. 

This week in maths, my group and I learned about the lowest common multiple (LCM). We focused on finding the smallest number that two or more numbers can divide into evenly. We explored different ways to work it out, like listing the multiples of each number and then finding the smallest one they have in common. Doing this helped me understand how multiples work and how to spot patterns more easily. We also looked at examples to help explain our thinking clearly, which made it easier to understand how the method works step by step. I improved my understanding of how to find the LCM and feel more confident solving problems using multiples.

LI : Understanding how to round numbers up to billions’ places and three decimal places.

This week in math, my group and I created a DLO about rounding numbers. We focused on how to round numbers to large place values like billions, as well as to decimal places. We worked together to explain the steps clearly, like finding the place value, looking at the digit next to it, and deciding whether to round up or stay the same. We also included an example to help others understand how rounding works. I got better at rounding numbers and understanding when to round up or keep the number the same. It also helped me practise working with my group and explaining math clearly.
