Magnificent Measurement Gather students in a large group. Ask them to name the different time frames within a day—morning, afternoon, and night. Have students share activities they participate in during the morning time (for example, wake up, eat breakfast, and brush teeth), afternoon (for example, eat lunch, play outside, and go home from school), and night (for example, eat supper, do homework, and watch TV). If students have difficulty, ask such guiding questions as “When do you eat breakfast?” Read the story The Grouchy Ladybug, by Eric Carle, to the class. After reading the story, introduce the attributes of time using real clocks. Distribute a copy of the Morning, Noon, and Night Activity Sheet to each student. Assessments At this point, it is important to assess whether or not students understand the attributes of time. Extensions For practice, have students at the upper end of the grade band, make their own ladybug clock. Questions for Students 1. [Student responses may vary.] 2. 3. Teacher Reflection

Mathwire.com | June 2011 MEDIAN Don Steward secondary maths teaching Horus Eye Fractions The ancient Egyptian system of measures provides another example of number signs conceived as a coherent system. In the so- called “Horus-eye fractions”1, the designer of a numerical sequence linked its members also into a unified whole derived from a myth, just as in the series of numerals for the powers of ten. Gay Robins and Charles Shute describe this series of measures in their book on “The Rhind Mathematical Papyrus”, an ancient Egyptian mathematics text for apprentice scribes : “The common unit of volume, used for measuring amounts of grain or flour, was the hekat, approximately equal to 4.8 litres or just over a [British] gallon. (...) For smaller amounts, the hekat could be progressively halved to give /2, /4, /8, /16, /32, and /64 fractions. (...) In Egyptian mythology the eye of Horus was wounded, wrenched out or eaten by the fearsome god Seth. They could also have shown that the sum was short of 1 by 1/64. (...) This so completed Eye had great symbolic importance.
