"carry the one."
It is important for the children to understand the value of the digits in order to take numbers apart and regroup them during computation. Strong number sense through place value strengthens the ability to mentally compute numbers over the long term and therefore, be less dependent on paper and pencil strategies.
Please see the video demonstrating the 3 strategies we have been practicing. We will begin to focus more heavily on the grouping strategy (also called "partial sums"). Don't forget to check the reasonability of your work with a "ballpark" estimate (like our rounding).
Thank you for ALL you do to support your child at home!
