This math assessment workbook focuses on practicing operations with decimals, including addition, subtraction, multiplication, and division. Students solve word problems that require determining appropriate operations to find the solution. They calculate differences or sums of decimal values. Quick computation items, such as 0.9 times 6 or 470 divided by 100, sharpen fluency by moving the decimal point. Students also work with multiplication and division of decimals, including multi-step word problems such as finding the weight of individual items given the total mass. Common Core skills for this unit include understanding the place value system and performing operations with multi-digit whole numbers and with decimals to hundredths.
