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

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.
Tree Measurement - fieldwork - L a n d L e a r n - Australia Contents: 1. Measurement in the field - techniques Introduction: Vegetation management on both public and private land, in farm forestry, native forests, gardens and parkland provides examples of monitoring techniques which can be applied with students. Understanding and applying the techniques used in the field to measure individual trees and stands provides students with an insight into the roles and work of forest and other natural resource management scientists. Students can collect data and, depending on the sites available, can use the information in management decisions for the site. Students will be able to: Equipment: (i) Data collection - Measurements of a single tree 1. The diameter of a tree provides a measure of tree performance and is required for estimating tree volume. By convention, the diameter of forest trees is measured 1.3 metres above the ground. When estimating tree volume it is best to have a value of 'Diameter at Breast Height Under Bark' (DBHUB). 2. 3. 4. 5. S.

Addition_and_subtraction Experiences before starting school On their arrival at school, small children are likely to be aware that the world of numbers exists, and may be able to: Recite the numbers up to 20 in order. Write the numerals 0 to 9. Grasp the connection between the numeral ‘3’, the word ‘three’ and a picture such as or . Motivation Addition and subtraction are two of the ways we work with numbers. Subtraction and addition are inverse operations. For example, 6 = 4 + 2 is equivalent to 6 − 4 = 2 and also 6 − 2 = 4. The ability to add numbers in your head is used when you play, or watch sport and when you buy a couple of items at the shops. Formal or written algorithms are useful when larger numbers make mental calculations difficult. A student will not develop a number-sense, or fluency with operations, if they move to calculators too quickly. Content A child can develop the basic ideas related to addition whilst investigating the place value system. Addition − and, add, plus, put together with, sum or Zero
