PS: The google form has a mistake. It says what number did you choose, then gives us the options A, B, C, D.
1 V2 2.50
The google form has a mistake it gives us A,B,C,D instead of us putting the answer
Do you mean 1 to 6 once on each line?
I made a spreadsheet to check interval lengths to project with class as kids are sharing answers. Make a copy of this spreadsheet if you’d like to use it too.
