Activities to Teach Students to Compare Fractions Using Benchmarks

Fractions can sometimes seem challenging for students to understand and even more challenging to compare. However, teachers can use benchmarks to help students compare fractions and make the process more manageable. There are numerous activities available that can help students compare fractions using benchmarks. Here are some of the most effective ones:

1. Number Line Activity:

Create a number line on a large piece of paper or on the classroom floor. Then, have students place fractions on the number line using benchmarks to compare them. For instance, if students are comparing ⅓ and ½, they could use ¼ as a benchmark and place ⅓ slightly less than ¼ and ½ slightly more than ¼ on the number line.

2. Fraction Bingo:

Create a bingo card that features fractions using benchmarks. Call out benchmarks, such as ¼ or ½, and have students compare the fractions on their bingo cards to determine which one fits the criterion. Students who get a line or a full card can call out “bingo” and win a prize.

3. Fraction Sort:

Provide students with a set of fraction cards that feature different denominators and numerators. Ask them to sort the cards into groups based on their benchmark. For example, students could organize fractions that are less than ½, equal to ½, or greater than ½.

4. Fraction War:

This game involves a deck of fraction cards. Students play in pairs, and each player starts with half of the deck. Each player turns over a card at the same time, and they must compare the fractions using benchmarks, such as ¼ or ½. The player with the larger fraction collects both cards, and the game continues until one player has all the cards.

5. Fraction Targets:

Create targets with different benchmarks on them, such as ¼, ½, and ¾. Provide students with a set of fraction cards and ask them to throw the cards onto the targets. Students then compare the fractions that land on the targets to determine whether the card is less than, equal to, or greater than the benchmark.

In conclusion, comparing fractions using benchmarks can be a fun and engaging learning activity that can help students understand the concept of fractions better. Teachers can use these activities or create their own to help students master this skill. Through practice and repetition, students can develop confidence in comparing fractions and become proficient in using benchmarks.
