What about counting backwards?
I am interested in Student Achievement Partners' interpretation of a few standards in Kindergarten. CCSS.MATH.CONTENT.K.CC.A.1 Count to 100 by ones and by tens.
CCSS.MATH.CONTENT.K.CC.A.2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1). There's nothing explicit about backward counting. We've often felt that many kids learn to count back from 10 in their daily lives as preschoolers or kindergartners. How about counting back from 20 through instruction in K? Then later in the year to 30? It would help solidify the rote sequence and lead to the "count back" strategy for subtraction, but I wonder how much time to spend on it. It seems like it could make for a warm-up small group or partner activity year-round, differentiated by where they are. I'd be interested in other people's thoughts on this topic.
