There is always a bit of stress awaiting the arrival of a printing of the books. In the past, the wrong books were sent, damaged books were sent, the cover color was off… However, having learned from those past experiences, I now ask for an advance copy before the truck leaves Michigan, and I give a reminder to the printer to not make the same mistakes as in the past.

Thankfully, all is well with this shipment. The books look good!

This printing says, “Supports Common Core State Standards” and on the inside of the front cover, there is a list of the standards that this book supports. Particularly, “By end of Grade 2, know from memory all sums of two one-digit numbers.”

That is basically what Two Plus Two Is Not Five covers on each of the workbook pages! The books also have some pages supporting Grade 1 standards too.

1.OA.3  Apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11   is known,  then 3 + 8 = 11 is also known. (Commutative property of addition.)
1.OA.4 Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the  number that makes 10 when added to 8.

1.OA.5  Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).

1.OA.6  Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating  the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

If you need a copy with a list of the common core state standards printed inside the book, please request this when ordering!
