Math-U-See Alpha pages 48 and 50- Adding zero to a number

The Alpha book is reviewing earlier concepts. Today, Megan practiced adding zero to a number.  She then had two number problems which, in the end, were practicing adding 0 to a number as well.  This was true for both pages. Megan did not feel like coloring this day and so she skipped page 49. We will come back to it.
