Term 2-Week 3 Addition and Subtraction

W.A.L.T Solve subtraction problems using place value partitioning

How I felt

I felt tired because there was a lot of strategy to do

57+28=85 50+20=70 7+8=15 70+15=85

1341-967= 1000-900=100 140-60=80 11-7=4 300+70+4=374

And you have 300 so add the 100 together and you will have 400.Also you can not take away 60 from 40 because 60 is high so borrow 100 from 400 and you will have 300. Impossible to take 7 from 1 so you have to borrow 10 from 80 and you will have 70 left

Kiwi sport

Today the senior school had it's first Kiwi sport session for this term.



Ben, from Auckland Badminton, taught us some badminton skills. We used a badminton racket and a shuttle.



We learned how to hit the shuttle using a forearm hit and backhand hit. Ben also taught us how to hold the racket using different grips.



I felt excited and happy because I kept on hitting the shuttle the most.

Maths work

Walt: solve subtraction problems using place values partitioning

1. Hilda collected 632 poppy flowers for ANZAC day but 289 flowers wilted before she could use them. How many flowers were left with her?

632-289=

600-200=40
400-100=300
100+30=130

130-80=50

50-10=40

12-9=3

300+40+3=343

So you can't take away 30 from 80 so you borow 100
from 400 wicth leaves you with 300 and you can not take away 2 from 9 so you borow 10 from the 50 and leaves you with 40 and add it all up and your answer will be 343

Cultural Festival

I am feeling very excited about taking part in  cultural activities at school this term.

Today I picked two cultural groups that I want to be in.

My first choice was Cook Island and I picked  Kiwi Jam as my second choice.

I am hoping I get my first choice.

Walt:  We are learning to use the problem-solving approach and five talk moves to solve addition and subtraction problems using various strategies

Success Criteria: I am able to use various strategies to solve addition and subtraction problems.

6559-2342=4217

6000-2000=4000

500-300=200

50-40=10

9-2=7

4000+200+10+7=4217

Math's work

How I worked it out

389+117=506

300+100=400

80+10=90
