This math assessment workbook focuses on reading and writing decimals as fractions and mixed numbers using place value language. Students practice identifying tenths and hundredths in fraction and decimal form. They match pictorial models to decimal digits, and they compare values. Problems require choosing fractions equivalent to given decimals and spotting nonequivalent pairs. Learners convert decimals to expanded form using fraction sums, and they simplify mixed numbers. Common Core standards covered are 5.NBT.3a and 5.NBT.3b for reading and comparing decimals, as well as 5.NBT.4 for using place value to round decimals.
