In LS2 we have been making DLO’s about maths algorthims. Algorithims are placements for the numbers that make the question that your doing easier. We have made Multiplication, Subtraction addition, short division and long division. After we finish these tasks we could do more in the future like rounding and decimals for example.
For Maths my group, group 2 created a DLO that shows others how to do algorithm subtraction. After we learned how to do algorithm subtraction something our teacher, Mrs Fisi’ahi tells us is to not worry about how big the number or how many numbers or subtracting it doesn’t matter because its always the same strategy that you use. Something I liked about creating this was helping the ones who didn’t know understand how to do algorithm addition.
Our group was revising on how to subtract decimals numbers using algorithm. It’s just like adding but one thing that you have to remember with subtracting the first number at the start has to be a the top and you subtract and if the number at the bottom of the numbers is bigger then the number a the bottom you have to borrow from the number next to it.
This week for Maths, group 2 of LS2 has been revising on Decimal Addition Algorithm, we will all explain how to add Decimal numbers using algorithm. One thing that I liked about adding decimal number with algorithm is that there is a lot of different ways you can solve this with different solution.
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.
Group 2 of LS2 have been learning and some revising on “Lowest Common Multiples” (LCM).
LCM consists of multiplication where you find the number in common between 2 numbers multiplication order. For an example you could use 4 and 7 up to 5 to find the LCM. You times both up to 5 and if there is the same number diagonal from eachother. (4, 8, 12, 16, 20.) and (7, 14, 21, 28, 35) in this case, there is no common multiple up to five. But if you know your four times tables if you add 2 on you can make it to 28, which the 7 times table has making it the answer.
Group 2 in LS2 have been revising on round numbers up to the billions.
Rounding is a useful skill to estimate. In this blog, we will be teaching you how to round. You need to know place values were you can find our example in our earlier blogs. To round you need a base number, I’ll pick a random one. (482.119) if rounding and you see a question asking to round to the nearest tenth you need to realise that the “th” means that it is in the decimal, not the whole number. in this number rounding to the nearest tenth would be the 1 after the 9 in the decimal place. due to the number being higher than 4, we round up. which is rounding to the nearest tenth. which would be 20 in this case. This would change the number to 482.120. I hope that this blog has taught you how to round.
For maths group two’s task was to learn how to solve place value problems and how we use place value in different area’s. Place value is the place of a digit in a number that tells us how much it is worth. For example if there was an equation that said what is 100 more than 4,628,297 the
answer would be 4,628,397.
For maths this week our main focus was Short division. So far we have been revising and answering questions that revolve around division using the short 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.
For maths this week our main focus was long division. So far we have been revising and answering questions that revolve around division using the 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.
