The attachment is a packet of five days of worksheets for first grade common core standard 1.NBT.5 Given a two-digit number, mentally find 10 more or 10 less than the number, without having to
count; explain the reasoning used. There are sections of a hundreds chart, places were students mentally change numbers, adding or taking away ten and a word problem with examples of strategies they can use and an area for them to write their explanation.
