What Are Benchmark Fractions?
Benchmark fractions are special fractions we use as reference points to help understand and compare other fractions.
They're like mile markers on a highway that help you know how far you've gone! The most common benchmark fractions are \(\frac{1}{4}\), \(\frac{1}{2}\), and \(\frac{3}{4}\). Knowing these helps us estimate measurements, compare sizes, and solve problems faster!
How to Use Benchmark Fractions
1️⃣ Recognize common fractions like \(\frac{1}{2}\), \(\frac{1}{3}\), \(\frac{1}{4}\)
2️⃣ Visualize them using pictures, pies, or number lines
3️⃣ Compare other fractions to these benchmarks

Parent Tips 🌟
- Kitchen Math: When cooking, ask your child to help measure ingredients using benchmark fractions ("We need half a cup of flour").
- Pizza Party: Use pizza slices to demonstrate fractions - cut a pizza into 4 or 8 slices to show \(\frac{1}{4}\), \(\frac{1}{2}\), etc.
- Estimation Game: Play "More or Less Than a Half" with everyday objects ("Is more or less than half of your juice left?").
