Purpose
You will investigate how fractions help you measure, scale, and adjust a baking recipe. Fractions are parts of a whole. Compare two batters and guess which worked better. Ask a grocery baker why measurement accuracy matters. Bake one recipe twice using equivalent fractions, different scales, correct units, tools, and portion control. Equivalent fractions are different names for the same amount. Journal after each bake. End each session by sharing one math win and one challenge. Use classmates’ taste-test cards to revise. Present before-and-after recipe cards, photos, and an improvement graph.
Learning goals
I can identify whole numbers, decimals, and fractions in recipes and measurement scales.
Fractions are numbers that show equal parts.
I can choose measurement units, abbreviations, and tools for liquids, dry ingredients, weight, and counts.
I can use equivalent fractions and baker’s percentages to scale recipes while keeping portions consistent.
I can bake twice, compare results, and revise measurements using feedback from a baker and classmates.
I can graph improvements and explain my fraction changes through recipe cards, photos, and reflection.
Products
Create a before-and-after recipe card with whole numbers, decimals, fractions, units, and scaled amounts. Scaled amounts mean amounts changed to fit a new size. Keep a journal and photo log comparing two bakes, results, changes, wins, and challenges. Record the grocery baker’s tool comparison and advice about accurate measuring and portion control. Comparison means how you compare two tools. Collect classmates’ taste-test cards, then use their feedback to revise your recipe. Build and present a graph showing how much the revised recipe improved.
Launch
Inspect two safely prepared versions of the same baked recipe. Guess which fraction changes improved the texture, size, and consistency. Fraction means a part of a whole. Compare measuring tools with a grocery store baker, and discuss why accuracy matters. Record how fractions might change a recipe without changing its final result.
Exhibition
Display your recipe cards, photo log, and graph. Show how much the revised recipe improved. Invite several classmates to taste allergen-labeled samples. Ask them to write one noticed change on a shared feedback card. Explain your fraction changes, final results, and classmates’ feedback to the audience. A fraction shows part of a whole. Hear a grocery baker compare tools and explain why measurement accuracy matters.
