Magnificant Maths



This is a simple way to solve hard math questions. 

My goal Is to use a broad range of mental strategies to solve addition and subtraction problems.
We had to learn three different strategies (Tidy numbers, Place value and Reversibility). Some were a little hard, but My Favorite strategy Was Place Value.

Here is an example:

123+321= 

100+300=400
20+20=40
3+4=7

400+40+7=447


I hope you learned something!

To support my learning I ask you to comment as follows:
1. Something positive - Begin with a greeting. Talk about something you like about what I have shared.
2. Thoughtful - A comment that will mean something to me to let me know you read/watched or listened to what I had to say. - use any language.
3. Something helpful - Give me some ideas for next time or ask me a question.
Encourage me to make another post
