Last week, Group 1 worked on Decimal algorithm together on Addition, Subtraction, Multiplication and Division. We explained on a DLO how to solve and work out how to use each operations in Maths. Most interesting I learnt is that each operation has a different strategy on how to solve the equation.
LI: How to name place and total values up to millions and two decimal places
Place value, is the value of every digit in a number depending on its position.
Decimals are parts of a number which always stays on the right side of the decimal points (.).
If this is difficult a easier way is relating whole number and decimals to money (Dollars and Cents) because dollars are whole numbers and cents are like decimal numbers because they aren’t a whole number.
For this weeks Maths , group 1 is learning how to identify highest common factors. Highest common factors is basically the largest whole numbers that divides into two or more numbers without any remainders. Remember , factors are numbers that we can multiply together to get a number. For example : 6 x 8 = 48.
LI : How to identify and round to significant figures.
For this weeks Maths , Group 1 created a DLO showing how to solve significant figures and to have a better understanding towards the learning. When needed if you need to solve a number and show all the figures in that numbers whether if it has 1 , 2 , 3 , 4 or 5 significant figures its really easy to solve and will better if know more about it.
Example:
886652 :
1 s.f = 900000
2 s.f = 890000
3 s.f = 887000
LI : How to identify Prime and Composite numbers.
This week for Maths we learnt how to identify Prime and Composite numbers. A prime number is a whole number which is only divisible by itself and one. A prime number only has 2 factors and if an number does have more than two, it is a composite number. For example : 5 is an prime number because 1×5 = 5 and there are no other factors. The first and only even prime number is “2”. other factors except 1 and 5.
LI : Understanding how to round numbers up to the billions place and three decimal place.
This week for Maths Group 1 worked on Rounding numbers. We created DLO’s showing how to use numbers and having an example to show how easy it is. Even if you find it difficult there are many ways to solve it. Remember to put commas when a number is over 1 million.
LI : How to calculate the quotient of whole numbers , using algorithm
For this week’s Maths , Group 1 learned how to do the division algorithm long and short. We figured out a way to solve the quotient but using the standard division method. Writing numbers in vertical with the bigger numbers on top. While you’re dividing the numbers, keep track of the remainder to make sure the problems have been solved correctly, using this method has made me confident when solving division and letting me have a better understanding.
LI : How to calculate the product of whole numbers , using algorithm
This week in Maths, Group 1 learned how to find the product of whole numbers using the standard multiplication method. We all worked on lining up my numbers properly and keeping my work neat so we didn’t get mixed up. I always reminded myself to add the place holder after each place value we finished multipling so I wouldn’t get mix up on with row I was on. Algorithm helped me solve my equation fast and simplliar to solve.
LI : How to calculate the difference of whole numbers , using algorithm
This week in maths, I learned how to calculate the difference of whole numbers using the standard subtraction algorithm. I practiced lining up numbers by place value and subtracting carefully from right to left. When the top digit was smaller than the bottom digit, I used regrouping to borrow from the next column. This method helped me stay organized and avoid mistakes. I feel more confident subtracting larger numbers now, and I understand why following the steps carefully is important.
LI : How to calculate the sum of whole numbers , using algorithm
This week in maths, I learned how to add whole numbers using the addition algorithm. First, I made sure to line the numbers up correctly by place value so the ones, tens, and hundreds were in the right columns. Then I added from right to left, starting with the ones. If the total was more than ten, I carried the extra number to the next column. At first I had to be careful and check my work, but the more I practiced, the easier it became. Using this method helps me stay organised and get the correct answer. I feel more confident adding bigger numbers on my own now.
