Square Roots

LI: How to calculate square roots of numbers.

In Group 4B we are on a new topic called Square Roots, we can identify and find a square root of a number by adding some of its factors then getting the last one to find it, or we can find it by using our multiplication tables we can use it by the second skip counting methods, which can be 7×7 which is 49 which means 7 is the square root of 49. While doing this we all had some different answers but in the end we all get how we can find the square root. It was also very fun at the end because we all got the right answers which helped us learn together.

 

Prime numbers

LI: How to identify prime numbers.

Group 4b has been learning about prime numbers and how to identify them. We created a DLO (Digital Learning Object) to explain our findings.

The main difference between a prime and a composite number is the number of factors they have. For example, 9 is a composite number because you can multiply $3 \times 3$ and $1 \times 9$ to get 9. Because it has more than two factors, it is composite.

On the other hand, 7 is a prime number. Notice how 7 cannot be multiplied by any other numbers except 1 and itself? That is what makes 7 a prime number. All prime numbers have exactly two factors: 1 and the number itself.

Lowest Common Multiple

LI: How to identify multiples of numbers and find the lowest common multiple of two numbers.

In Maths, we have been learning all about the Lowest Common Multiple (LCM). To find the LCM, we first practiced identifying the multiples of different numbers by skip-counting (for example, the multiples of 3 are 3, 6, 9, 12…). Once we mastered listing multiples, we learned how to compare the lists of two different numbers to find the very first, smallest multiple they have in common. For instance, we discovered that when looking at 4 and 6, the lowest multiple they share is 12. This focus helped us understand how numbers connect, which is a super useful skill for solving trickier fraction and division problems later on.

Short Division

In LS2, we explored short division, a streamlined method for handling large numbers efficiently. One student noted that their favorite part is the step-by-step process of solving the equation; they find the logical progression toward the final answer particularly rewarding .

I enjoyed learning a new maths skill.

I learnt that for short division it’s a rotation , divide , subract , multiply and repeat.

I need to improve on working faster.

Multiplication Algorithm

This week  for maths we are working on doing multiplication algorithm in our books , this is Group 3 DLO .

Example ,Think of a 3-digit multiplication algorithm as a “power up” for your math skills. Instead of adding a number hundreds of times, you break the big number into three smaller jobs: the ones, the tens, and the hundreds. You start with the single number at the bottom and let it “visit” each digit on top, starting from the right and moving to the left. If a visit results in a number 10 or higher, you simply “carry” the extra digit over to the next neighbor’s head, like a little hat. You multiply the next set of numbers first, then add that “hat” to the total before moving on. Once the bottom number has visited everyone on the top floor, you have your final, giant answer.

I enjoyed how we worked together if one person didn’t know the answer and that we would help each other to understand what we are doing and how to understand multiplication algorithm .

Addition Algorithm

LI: How to calculate the sum of whole numbers, using Algorithms.

One of our main focus for maths this week is using Addition Algorithms to solve whole numbers. We had to read  the examples carefully and answer questions on our board so that we can get a better understanding. I have created this DLO to show you how you can master Addtion Algorithms too

Maths Algorithm DLO

LI: Subracting using Algorithm .

This week for Maths,we learned about subtraction and addition problems. If you need help on subtraction algorithim, you should read this DLO. Subtraction is basically vertically aligning digits by place value meaning (ones,tens,hundreds) and subtraction from left to right while borrowing a number if you can’t subtract the bottom number . If the top digit is smaller, “borrow” (regroup) 10 from the next column. K include: Borrow/regroup if needed .I enjoyed these equalization , these questions were slightly tricky but I had fun !
