First they will halve the ingredients and rewrite the recipe, and then they will double the ingredients and rewrite the recipe. The student will be asked to reduce the measures to simplest form. Print out the recipe. They will then double the measures of the recipes and write the recipe again. All fractions will be simplified.
Students can evaluate recipes for nutritional content.
Students can search for a recipe for their favorite food and halve and double its recipe. Students can convert the measurements to metrics. Students may need to review the terms 'double' and 'halve' and how to double and halve the fractions. If you are not the author but used this lesson plan, please send your comments to the web master.
