Dylan`s Multiplying integer scribe post

Hey every body what well i got or a scribe post today was the odd numbers of pages 296 and 297 so heres the first two

this is what i did for the odd questions on 296

1.Darcy modelled (+7) × (+3) on a number line by drawing seven
arrows. Ishnan modelled (+7) × (+3) on a number line by
drawing only three arrows. Explain Ishnan’s thinking

The last question on 296 was some what the same and here it is

2.Without doing any calculations, Wei said that -19 and +27 have
the same product as +19 and -27. How did she know?
again my answer was: She knew this because -19 and 19 have the same value but different place values the same goes for 27 and -27

thats what is did for question 5 a

here's question 5 b

the last and final question is the easiest
A) 10x4=40
B) 2x9=18

1. Good job Dylan! I liked your pictures, because they were easy to read. But next time maybe add a video and a link to something good. Overall good job!
