Previously Published Data 

1.) Students will show and record equivalent fractions with and without using manipulatives. 

2.) Using 4 inch squares, each student will divide ten of them into a variety of fractional parts and color the parts. All will combine their squares to make a large, rectangular display for the classroom that resembles a crazy quilt made of paper. Students will identify the fractional pieces in this display. 



Previously Published Data 

1.) Given fractional pieces from 1/2 to 1/12 (depending on which fractional parts are being assessed), students will combine the pieces to make wholes and record their work.  

2.) Given a worksheet of circles, squares, rectangular, and triangular shapes, students will write fractional parts that equal one whole, such as 6/6 = 1 whole. 

3.) Students will indicate equivalent fractions, with and without using fractional  pieces, such as, among fourths, halves, and twelfths.
