Educational Benefits

These games focus on the concept of the decimal and offer a vast array of different exercises for several specialized subjects, all presented in a fun and meaningful online learning environment.

They combine lessons from basic arithmetic skills, such as adding, subtracting, dividing, and multiplying decimals. Children can also learn about place value and rounding of decimals, and comparing and ordering different numbers as well.

They can also work on converting fractions to decimals and vice versa.

Most of the games focus on one specific subject, so students and teachers can choose games that meet the individual learning needs of each child.

The games here are great for 5th grade students and provide just the right level of challenge for students of that age group - fostering learning by challenging their skills, but not frustrating them by asking them to solve equations beyond their ability.
