This week, Group 1 got to make a DLO to explain how to work with significant figures in numbers on the DLO. Significant figures are the important digits in a number that show its precision. The resource helps you understand how to keep track of these digits when solving math problems.

The idea is that sometimes you need to show all the significant figures in a number, whether it has one, two, three, four, or five. Doing this makes it easier to work with the number correctly. For example, if you have the number 886,652, and you want to round it to different significant figures:

– To have only 1 significant figure, you look at the first digit and round the number to the nearest hundred thousand, so it becomes 900,000.
– To have 2 significant figures, you keep the first two digits, which are 88, and then round, making it 890,000.
– To have 3 significant figures, keep 888, and the number becomes 887,000.

One interesting fact I learnt was that if I shows these steps clearly, it is making it easier for students to understand how to identify and work with significant figures. Whilst also understanding how to do this is useful because it helps make measurements and calculations more accurate and consistent, especially in math.

This week in math, Group 1 is learning about something called the highest common factor. Basically, the highest common factor is the biggest number that can divide into two or more numbers exactly, without leaving anything left over.

To understand this better, think about what factors are. Factors are numbers that you can multiply together to make a bigger number. For example, if you multiply 6 by 8, you get 48. So, 6 and 8 are factors of 48.

When we talk about the highest common factor of two numbers, we are looking for the biggest number that can fit evenly into both of those numbers. For example, if you look at 12 and 18: the factors of 12 are 1, 2, 3, 4, 6, 12; and the factors of 18 are 1, 2, 3, 6, 9, 18. The biggest number that appears in both lists is 6. So, the highest common factor of 12 and 18 is 6. This means 6 is the largest number that divides evenly into both 12 and 18.

One interesting fact I learnt was if I taught students and learnt st getting good at finding the highest common factor it helps them to understand how numbers relate to each other and can be useful in many math problems, like simplifying fractions or dividing things into equal parts.

Today for this task we learned about two types of numbers prime numbers and composite numbers. Prime numbers are special because they only have two factors: 1 and the number itself. For example, 3 is a prime number because only 1 and 3 can be multiplied together to make 3. Another example is 5. These numbers can’t be divided evenly by any other numbers except 1 and themselves.

On the other hand, composite numbers are numbers that can be divided evenly by more than just 1 and themselves. This means they have more factors. For example, 6 is a composite number because it can be divided evenly by 1, 2, 3, and 6. Because of this, most even numbers like 4, 6, 8, and 10 are composite numbers. The only even number that is prime is 2, because it only has two factors: 1 and 2. All the other even numbers have more factors, making them composite. Basically, prime numbers are like numbers with only two factors, and composite numbers are like numbers with a bigger group of friends they can be divided by.

LI: How to calculate the quotient of whole numbers using algorithm

For maths this week our main focus was Short division and long division.  So far we have been revising and answering questions that revolve around division using the short and long method.  We put together a Google slide to help/explaing to people how to do short/long division.  Have a Look! I hope this helps you.

LI: to calculate the product using whole numbers.

For this weeks  our focus for maths was multiplication algorithm to find the product(anwser) using algorithm. We answered 15 questions revolving around using multiplication algorithm, Once we had finished, we made a DLO explainging what we did and how we did it, to help people understand adn to learn how to use it. Check out my DLO to see what I have wrote!

This week our main focus in maths was subtraction using algorithms, so we could get a deeper understanding of it. To do subtraction algorithm it is harder to understand but once you get the hang of it is flawless. Have  a look at the DLO me and my group made to help people get a better and deeper understanding!

For this week our maths focus was doing addition by using algorithms and having a deeper understanding of it. Once we finished our book work for the addition, we made a DLO so others could understand how to do it, and give people a better understanding. Take a look at the DLO I made with my group.

LI: To subtract fractions

Maths this week, we have been learning to subtract fractions.  First we needed to explore and discuss how to subtract fractions in order to understand,  then needed to discuss as a group and work out on white boards the examples given.  Before needing to complete our individual work in our math books.  This DLO explains and teaches how to subtract fractions.
