CLE M /s/t: Fractions Lesson Title: Inch by Inch Source: http://illuminations.nctm.org/LessonDetail.aspx?ID=L545 Curricular Connections : Math Materials : standard ruler for each student and activity sheet, also a blown up ruler for the board. Grade Range : 3-4 Lesson Overview : Students will use rulers to represent various fractions as lengths. Students will use a ruler to measure a variety of items, including items which can be measured to the nearest half and quarter of an inch. M/S/T Standards and Evidence Students Will: (3.N.10) develop an understanding of fractions as part of a whole unit and as parts of a collection. Evidence: Students will be developing an understanding of how inches are a fraction of a foot, and inches have fractional parts that make up one whole inch. (3.N.11) use manipulatives, visual models, and illustrations to name and represent unit fractions (1/2, 1/3, 1/4, 1/5, 1/6, and 1/10) as part of a whole or a set of objects. Evidence: The students will be using rulers as a visual model and their activity sheet will have illustrations to represent fractions. (3.N.13) recognize fractional numbers as equal parts of a whole. Evidence : Students will be learning fractional parts of an inch, ½ inch and a ¼ inch. (3.N.15) compare and order unit fractions (½, , ¼) and find their approximate locations on a number line. Evidence: Students will be able to find these fractions of an inch on a ruler. (3.M.1) select tools and units (customary) appropriate for the length measured. Evidence: Students will be using rulers. (3.M.2) use a ruler/yardstick to measure to the nearest standard unit (whole and ½ inches, whole feet, and whole yards). Evidence: Students will be using standard 12 inch rulers to measure to the nearest whole and half inches. (4.N.7) develop an understanding of fractions as locations on number lines and as
