Ten Frames and Addition Facts < or = Ten Matching
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
Students develop strategies for adding and subtracting whole numbers based on their prior work with small numbers. They use a variety of models to develop meaning for the operations of addition and subtraction. Students understand connections between counting and addition and subtraction (e.g., adding two is the same as counting on two).

About 49 Ten Frames showing addition facts and 49 Addition Facts Cards less than and equal to ten are included. Also given are the numerals 2, 3, 4, 5, 6, 7, 8, 9, and 10 to represent the Sums of the Ten Frames and Addition Facts Cards.
Setting Up the Activity:
Use cardstock to make the cards. Separate the cards into 3 sets.
Set A: Sums of 2, 5, 10
Set B: Sums of 3, 6, 9
Set C: Sums of 4, 7, 8
Students should separate the ten frame cards from the addition facts. They should first match the ten frame cards to the sums in each of the 3 sets. Then they should match the addition facts to the ten frames and to the sums in each of the 3 sets.
