Building number sense with decimals is no different. We have to give students plenty of experiences seeing and working with decimals in different ways in order to see increased number sense with decimals.

There are certain concepts in math that are pretty obvious in which order they should be taught.  Clearly students should learn to add before they learn to multiply, or divide whole numbers before learning to divide decimals. What I found is not so clear among many teachers and those district leaders who write our pacing guides is what comes first?
