Product Description
NOTE: This is part of my -2nd GRADE NO FRILLS BUNDLE - you might rather check that out than purchasing a single item! =)

This is a pdf file of 2 worksheets with answers.

This is a no frills exercise designed specifically to address the “make 10” strategy for these Common Core standards:

1.OA.6
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using 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).

2.OA.2
Fluently add and subtract within 20 using mental strategies.* By end of Grade 2, know from memory all sums of two one-digit numbers.
*See standard 1.OA.6 for a list of mental strategies

Centers and games are great reinforcement – but sometimes in the crunch, you just need some papers to send home, or to be able to differentiate easily! I’m working on a series of Common Core “No Frills Practice” for 2nd grade. THIS product and the list below are all part of this 2nd GRADE NO FRILLS BUNDLE.
