As students enter upper elementary and middle school math classes, they are introduced to rational numbers such as fractions, decimals, and percents. It is essential to teach students to compare and order rational numbers to help them understand their value and relationship to one another. Here are some activities to teach students to compare and order rational numbers.

Fraction War:

This game is played similarly to the traditional card game of war. Divide the class into pairs, and each pair receives a deck of fraction cards. Each pair flips over a card at the same time, and the student with the greater fraction takes both cards. The game continues until one student has all the cards. This game reinforces the concept of comparing fractions with different denominators.

Decimal Line-Up:

Give each student a decimal card and have them line up in order from least to greatest. Once they have completed the task, have them switch cards with a classmate and line up in order again. This activity not only reinforces the concept of ordering decimals but also encourages communication and collaboration among classmates.

Percents Scavenger Hunt:

Place various percent cards around the classroom or school, and have students find them. Once they have found the cards, they must order them from least to greatest. This activity helps students understand the relationship between percents and whole numbers.

Fraction Tiles:

Fraction tiles are a visual and tactile way to understand and compare fractions. Students can use fraction tiles to create fractions with common denominators and compare them. This activity helps students understand equivalent fractions and comparing fractions with the same denominator.

Math Mystery:

Create a math mystery activity where students must use their knowledge of comparing and ordering rational numbers to solve the mystery. This activity can be done in teams or individually and is an engaging way to reinforce concepts.

These activities can be adapted for various grade levels and can be used as a supplemental activity or in-class assignment. By using these activities, students will develop the necessary skills to compare and order rational numbers and build a foundation for more advanced math concepts.
