Word Problems

LI: To practise figuring out word problems in addition and subtraction.

This week for Maths we had to solve maths problems by using either subtraction methods or addition. We had to solve a variety of different equations. We also learnt how to use the standard algorithm method. The main methods we used were Compensating, Place Value Addition, PV Subtraction, and Adding in parts. We had read the word problems to find out the equation. We had an agent number and  a starting number, the agent number is the number that changes the starting number.

Place Value

LI: to shift between place values using multiplication.

This week we have been doing place value numbers. We have been talking about making numbers smaller or bigger. By making numbers smaller we have to divide it. To make the numbers bigger we have to multiply it. Dividing the numbers shows that you can have numbers smaller than 1 but bigger than 0.

e.g

3  ÷  10 = 0.3 

3 x 10 = 30 

Place Value

So Today I had to watch a video about using place value. So This is how I did it:

I started with the 1’s. I took away 5 from the 6 and it was 1. Then I took away 6 from the 7 which equals 1.

And then there was 8, 0  then since there was A 0 it was still 8. So add all those numbers together and it turned out to be 811.
