 Oral / MentalStarter Objectives OutlineActivities Resources Monday L.O. Toread, choose, use and record standard metric units to estimate andmeasure length, weight and capacity to a suitable degree ofaccuracy. Ask the childrenquestions about suitable methods and units of measure. Whatcould I be measuring if I used a 1 litre jug?.. a metre stick?.. aruler?.. an electronic weighing scale?.. a 10ml measuringcylinder?.. a 5ml spoon? Discuss appropriate units ofmeasure. Individualwhiteboards and pens Tuesday L.O. Tointerpret a reading that lies between two unnumbered divisions on ascale. Using the thermometerITP, indicate temperatures on the scale ad ask children to readthem. Include negative numbers. ITP thermometer Wednesday L.O. Tointerpret a reading that lies between two unnumbered divisions on ascale. Use the thermometerITP to count differences between temperatures. Demonstrate usingthe scale, how to count through the 0 when calculating differencesbetween positive and negative temperatures. ITP thermometer Thursday L.O. Todescribe the occurrence of familiar events using the language ofchance or likelihood. Indicate theprobability scale drawn on the board. Pose a variety of statementsand ask individuals to come and indicate where on the line theywould place the probability of each event. For each statement theymust discuss their reasons. Probabilityscale Friday L.O. Todescribe the occurrence of familiar events using the language ofchance or likelihood. Repeat the activityfrom yesterday, also asking: Tell me an impossible event. Why?Tell me a certain event. Hoe could I make it certain that I shouldthrow a 6 using a dice? What would I have to do? What is theprobability of my throwing a number bigger than 3? Probabilityscale

 Key points forplenary Learning outcomes /difficulties/ misunderstandings Monday Ask thechildren to tell me an event that is certain or impossible. Askthem how they know. Ask: At the beginning of a hickey match,what is the probability that one of the sides will win>? Or thatone of the sides may score a goal? Discuss how some events mayhave an even chance of occurring. Tuesday Discuss howdifficult it is to find things that are certain or events that havean even chance of occurring. Pose the question: Do you think thelanguage of probability is the same in all countries? Do you thinksome languages have words with different shades ofmeaning? Wednesday Tell mea rule for working out the smaller divisions on a scale. Whatinformation must I have to be able to do this?Use a number ofexamples. Thursday Ask thechildren for their results and ask a volunteer to measure the itemaccurately, using a marked metre stick. Discuss degrees ofaccuracy. Ask: what intervals did you need to work out on yourhome made metre stick? What calculations did you have todo? Friday Hearsuggestions for solving this problem. Ask groups to describe theirway of working. Discuss margins of error and how it is verydifficult to be accurate with such a very small measurement.
