Andrew Todd on 02 Feb 13CCSS.Math.Content.1.OA.C.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

ELL and low English speaking students would benefit from the discussion present when solving long addition, subtraction, or multiplication problems with a partner.

Game could be modified or extended for higher grades by allowing the students to draw four cards each, then arrange them in a way to represent a 2-digit by 2-digit multiplication problem. The player with the highest total gets all four cards.

Shuffle deck and place cards in a pile face down. Players take turns taking a card until both players have 4 cards (for double -digit addition) or 6 cards (for triple-digit addition) and arrange them to make a two- or three-digit addition problem. The object is to make the greatest sum. When each player is done arranging their cards, they write their problem down and find their sum. Players exchange papers and check each other's addition
