WALT: Add and Subtract.
This week in Maths teacher lesson always to look at the number on the right before answering. The reason why to do this is so that you know if the number is going to end up in the next column. For example: 273+183=?. The way that I solve this is by doing this, 3+3=6, 170+180=350 then add the other hundred. The answer that I ended up with in the end is, 456. So my advice for you is to use this way to solve addition and subtraction questions.

Problem Solving-Week 4
WALT: Add and Subtract.
In Problem Solving this week, I have learnt to look at the number in the right. For example:1893-546=?, before I answer I am going to look at the last two numbers. So 13-16=7, after that we solve the rest of the question. The end result would be 1347.(if you did not know, Moi means me in French)

Maths Problem Solving-Week 3
WALT: Add and subtract decimals.
Start Writing Here: In Problem Solving I have been learning how to solve questions on my own. I have learnt that sometimes it is okay to solve questions with the simple solution. For example; 0.87-0.64=?. The simple way to work this out is by spiting them and then subtracting. It looks like this 0.8-0.6=0.2 and then we do 0.07-0.04=0.03. Once I have done this I will have the answer, 0.2+0.03=0.23. So the answer would be 0.23.

Maths Problem Solving-Week 2
WALT: Add and Subtract Decimals.
In Maths for this week, I have learnt about subtracting decimals. I have learnt that when subtracting decimals, always go to the small number first. For example; 4.7-2.9=?. The way that I use to work this out is, 0.7-1.9=0.8. I still have these numbers leftover to subtract, 4-1=3. So the aweser must be 1.8.

Maths Teacher Lesson-Week 1
WALT: Add and subtract decimals.
In Maths Teacher lesson this week, I learnt the place values of a decimal. For example; 26.5837, the number 8 is in the hundredths. I know this because it is two numbers away from the point and there is two zero's in hundreds. This is how I see which of the place value is the number in.

Problem Solving-Week 1
WALT: Add and Subtract Decimals.
In Problem Solving this week, I have learnt about decimals and how to add and subtract them. One thing that I have learnt is that when you subtract decimals, is it better if you just subtract the numbers one by one.
For example;7.5-2.4=5.1. I know the answer, because if we split the numbers like this, 7, 0.5, 2 and 0.4, we can subtract from there. So what we would do first is subtract 2 from 7 and we would end up with 5. The next thing that we would do is, subtract 0.4 from 0.5 which would equal to 0.1. So if we add 0.1 and 5 together, we would end up with 5.1. So that means that 5.1 is the answer.

Maths Teacher Lesson-Week 10
WALT:Add and Subtract fractions.
For the last few weeks in Maths Teacher Lesson, we have been learning about adding and subtracting fractions, then we learnt how to simplifier that fraction. For example; 6/20 + 4/20 = 10/20. We can make this simpler by doing this; 10 divided by 2=5, 20 divided by 2=10. Once we have done that we try and do it again 5 divided by 5=1 and 10 divided by 5=2. So if we put 1 and 2 into a fraction, it would make 1/2. The answer to 6/20 + 4/20=1/2 or 5/10 or 10/20.

Maths Teacher Lesson-Week 9
WALT: Add and subtract fractions.
In the last few weeks in maths, we have been learning how to add and subtract fractions. I have learnt when adding fractions you do not add the denominator, only the numerator. For example; 3/18 + 6/18 + 4/18 = 13/18. I know the answer because you do not add the denominator. All I did was, 3+6+4=13. Once I did that, I put the 18 with it. I thought if I could make it simpler fraction, but I could not because it is an even and odd fraction. So the answer is 13/18.

Problem Solving-Week 10
WALT:Add and Subtract fractions.
In Problem Solving this week, I have learnt that there are lots of ways to find the answer to fraction problem. Like subtraction, division,multiplication and addition. For example:there are 4/13 of apples eaten in the morning. In the afternoon there was 12/13 apples left. How many apples were eaten between the morning and the afternoon? One way we could find the answer is this:4+8=12. Another way we could find the answer is by doing this:12-4=8. SO the answer is 8!
