This is an enormous, comprehensive packet on the subtraction strategy counting back. This packet addresses Common Core Math Standards 1.O.A.5 and 1.O.A.6. There are visual aids/anchor charts, bump games, worksheets, clothespin games, and fill in the blank activities. The bump games come in Christmas theme and in non holiday format. They also come in black and white. The clothespin games come in Christmas/winter theme and also non-holiday themes. I did this so you could practice this strategy all year and not have to buy multiple items. I wanted to design a packet that could be used all year, and this is it! There are counting back from 120 practice sheets that provide more support at first and gradually the support is reduced. There is a blank 120 form for students to fill in. I hope you like this packet. This is the largest one I have made. Please leave feedback! Thanks!
