Mental Math - Adding One!


Adding One – Adding one means counting up, or jumping up on a number line, or counting up one number.  This happens every time you add one.  It is consistent.  It never changes.  Never recount the larger number, just say it – and then count up one.

7 + 1 =  say 6 then 7 (count up by one)
32 + 1 = say 32 then 33 (count up by one)
