Recognizing Student Achievement
Use journal page 253 to assess students’ ability to rename fourths, fifths,
tenths, and hundredths as decimals and percents. Students are making
adequate progress if they are able to fill in the missing numbers and shade the
grids. Some students may use shading that involves full and partial squares.
