Benchmark fractions are special fractions that help us understand other fractions better. They’re like the superheroes of math—always ready to save the day when things get tricky!
Imagine you're slicing up a pizza 🍕. You know that half of it is 1/2, and splitting it into quarters gives you 1/4. These pieces are easy to recognize and compare with other slices. That’s what benchmark fractions do—they give us a starting point for comparing numbers!
First comes 1/2, then comes 1/4… oh, and don’t forget 3/4 too!
1. Think of 1/2 as the middle piece—it’s
exactly halfway between nothing and the whole thing.
2. Now think smaller: 1/4 is just one little
slice out of four equal parts.
3. And bigger: 3/4 means three slices out of
those same four parts.
4. Use these friendly fractions to figure out if another fraction is close to them or far away.
Say we have a fraction like 2/3. Is it closer to 1/2 or 3/4? Hmm… let’s see:
- Imagine your pizza again 🍕. If you cut it into thirds, each piece is bigger than a quarter but not
quite as big as half.
- So 2/3 is closer to 3/4 because both are almost full slices!
1. Use real-life objects like pizzas 🍕, cakes 🍰, or even toys to show how fractions work.
2. Sing along while counting: “One-half is the star, one-fourth is small, three-fourths is
tall!”
3. Play games where kids guess which benchmark fraction a new fraction is closest to.
4. Celebrate their wins—even the tiny ones—with high-fives and cheers!
🌟 Wow! You’re a math superstar! Keep practicing, and soon you'll be a fraction master! 🎉
