Students in grades 5 and 6 were part of a Decimal class based on the teaching of Marilyn Burns. To ensure students understood the relationship between decimals and fractions students used tens blocks to represent wholes, tenths, hundredths and finally thousandths. Playing games such as Sum and Difference, Decimal Wipe Out, Smaller to Larger, helped children practice comparing, ordering, adding and subtracting decimals. Soon students will work on the relationship between fractions, decimals and percent.
