Say, “Since the shaded area is the same for both squares, then 1/10 (lay down the 1/10 card in front of the equal sign) and 10/100 (lay down the 10/100 card after the equal sign) are equal.” Now, show me that these two fractions are equal. Student lays down/selects a card labeled with an equal sign. Then, the student lays down/selects the 1/10 card in of the equal sign and lays down/selects the 10/100 card after the equal sign. “Good job showing that 1/10 and 10/100 are equal.” Test Materials Teacher Says/Does Student Response Teacher Feedback Student: Image of a square (the size of a base ten flat) that has been divided into ten equal parts (the size of a base ten rod), with one of the parts shaded.
