Andrew Todd on 02 Feb 13CCSS.Math.Content.3.NF.A.3d Compare two fractions with the same numerator or the same denominator by reasoning about their size. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

This activity would be beneficial for ELL students because they could discuss with classmates why the two different parts (represented by the cards) makes one whole. It would give ELL students opportunity to construct own meaning for concepts represented. It could be extended by adding unline denominators, which would require students to simplify or factor to find the answer.

Students play a card game with fractions. Every card has a fraction on it. The game begins with one card turned over and apart from the pile. Player 1 draws the card that is NOW on top of the pile. If the two cards make one whole, the student takes the pile. If it does not make one whole, place Player 1's card on top of the first card drawn. Player 2 now draws a card to see if it makes 1 whole with Player 1's card.
