 Number Benchmark H, Grades 5-7, Mini-Collection The grades 5-7 Number, Number Sense and Operations Benchmark H: Use and analyze the steps in standard and non-standard algorithms for computing with fractions, decimals and integers is one of the benchmarks most frequently tested on the 7th grade Ohio Achievement Assessment (OAA). The lesson materials and assessment items in this mini-collection support instruction related to this benchmark.

 Divide and Conquer (ORC#: 5812) Students can better understand the algorithm for dividing fractions if they analyze division through a sequence of problems starting with division of whole numbers, followed by division of a whole number by a unit fraction, division of a whole number by a non-unit fraction, and finally division of a fraction by a fraction. A lengthy list of guiding questions, summary questions, an assessment task, a lesson extension, and a set of carefully sequenced activity sheets are included. (sw)

 Multiplying Integers Using Videotape (ORC#: 1167) In this lesson, multiplication of integers is presented in a format that encourages understanding, not simply rote memorization of rules. Using the rewinding of a videotape to represent negative time, students convince themselves that a negative rate times a negative time yields a positive distance. A student worksheet and Internet extensions are included. This lesson is adapted from an article that appeared in the November 1993 issue of Arithmetic Teacher. (author/sw)

 Nutrients by the Numbers: Using Math to Explore Nutrition (ORC#: 1501) Students strengthen their percentage and fraction skills by comparing the nutritional values of similar food products. They individually calculate their own daily intake of various nutrients and compare their diets to recommended daily percentages. Older students might create a dietary spreadsheet to track their daily intake of various nutrients. Discussion questions, additional activities, suggestions for assessment, and Internet extensions are included with the lesson plan. (author/sw)
