I am a Year 4 student at Papakura Central School in Auckland, NZ. I am in Room 12 and my teacher is Miss Izelle. This is a place where I will share my learning. Please note that some of it will not be complete, it will be my first draft. Remember to be positive, thoughtful and helpful when you leave me a comment.
Hi Quinn, really good thinking shown in your think board. Think board 1: You've used place value partitioning by separating the hundreds, tens and ones. I really liked your interesting word story problem too.
Another strategy could be making tidy numbers. 123+47 You can take the 3 away from 120 and add it onto 47 = 120 + 50 = 170 (See how the 47 becomes 50 which is a tidy number?)

123+47

= 120 + 50
= 170
(See how the 47 becomes 50 which is a tidy number?)
Or 28+9
= (28-1) + (9+1)
= 27+10
= 37
