math create

Hello my name is Louis and today I am going to show you my math that I have been doing this week. goal : use a broad range of mental strategies to solve addition and subtraction problems. this is my work down below.

my favorite strategy is place value because it is simple and easy you need to add the hundreds, then the tens and finally the ones.

320 + 407 = 

300 + 400 = 700

20 + 0 = 20

7 + 0 = 7

= 727




have you used these strategies before ?

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
