Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 5–8 Professional Commentary: Students use the average adult's number of heartbeats per minute to predict how many times the heart beats during various lengths of time. Many of the problems can be worked in more than one way.... Career Fields: Agricultural & Environmental Systems, Health Science, General Career Skills Projects: Standards First 503 The Beat of Your Heart: Heartifacts Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 6–8 Professional Commentary: Students apply several pieces of given information about the heart to answer six questions. Students also create and solve an original problem using the listed "fast facts." An activity sheet, answers, and extensions are included.... Career Fields: Health Science Projects: Standards First Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades PreK–2 Professional Commentary: In this introductory lesson on combinations, students color all possible clown faces meeting specified criteria. An activity sheet, solutions, and problem extensions are included.... 505 Combinations: Shorts and Shirts Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 2–4 Professional Commentary: In this first of two lessons on combinations, students color all possible outfits meeting specified criteria. An activity sheet, solutions, and problem extensions are included.... 506 Combinations: Ice-Cream Cones Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 5–9 Professional Commentary: In this last of two lessons on combinations, students find all of the different double dip ice cream cones that can be made from eight flavors of ice cream. An activity sheet, solutions, and problem extensions are included.... 507 Representing Data: Whale Weight Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 6–8 Professional Commentary: In this lesson students examine the relationship between the length and weight of a whale. For this real-world application of mathematics, students must perform simple unit conversions and use proportional reasoning to complete a table of the lengths and weights of whales and determine if the results can be generalized. An activity sheet is included....

Students construct a simple pan balance and find the weight of small objects in "paper clips." In an extension of the lesson, they use their measurements to compare the weights of the objects.... 509 Playing Games: The Celebrated Jumping Frog Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 3–5 Professional Commentary: Using the story "The Celebrated Jumping Frog of Calaveras County" by Mark Twain, students simulate a jumping-frog contest and determine the distances "jumped." The students record the distance of individual jumps in centimeters and determine the total distance jumped (the sum of the three separate jumps) and the official distance (the straight-line distance from the starting line to the end of the frog's third jump). The students compare the range and median of the total distances with those of the official distances of the group.... 510 Ideas with Food: A Brownie Bake Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 3–5 Professional Commentary: Students do some mathematics in preparation for making brownies. They consider the inverse relationship between the base area of two different sizes of cake pans and the thickness of the same volume of batter poured into each pan.... |
