In learning to add decimals:
UI: I know the digit farthest to the right is always in the ones place and that numbers get ten times larger as they move to the left.
CI: I see there is a dot in the middle of the numbers, but think it works like a weird comma, and don’t know what to name the those numbers.
CC: I know the dot is a decimal that separates the whole numbers from values less than one, and understand as they move to the right, the numbers get ten times smaller.
UC: I can add decimal numbers like a normal number as long as I keep the dots (decimal) in the same column.
