Baking with Fractions

In this activity Students practice manipulating fractions for making a food following a recipe. Students are given a recipe which has fractional ingredient measurements and use the original recipe to convert the it to make a smaller portion (1/2 , 2/3, etc.). This lesson uses math, science, and language arts skills. It also supports Social Studies, in that the recipe  is “Hard Tack” which was a food used by soldiers and pioneers in the 1800’s during travel/war times.
