Calculate the perimeter A maths lesson for primary school corso CLIL c/o istituto Galvani – Giugliano corsista: Carmela Ruggiero

Teaching aims  Calculate the perimeter of regular and irregular quadrilaterals corsista: Carmela Ruggiero 2 Content  To enable learners how to calculate perimeter of regular and irregular quadrilaterals;  To enable learners to practice TL communication skills.

 KNOW  formulas to calculate the perimeter of regular and irregular quadrilaterals;  vocabulary, structures and functions on the topic  BE ABLE TO  classify quadrilaterals according to different criteria using a Venn diagram;  make predictions;  observe and record findings  BE AWARE  some quadrilaterals have equal sides corsista: Carmela Ruggiero 3 Learning outcomes

The assessment focuses on subject content and awareness of language structures and oral fluency  STEP ONE: summative assessment  Learners do a test on the computer after an interactive revision unit.  STEP TWO: formative assessment  After the learners calculate some perimeters, the teacher asks them to explain what and how they have worked and then gives feedback on their answers corsista: Carmela Ruggiero 4 Assessment

 REVISITED  sum, multiply, add, calculate, transform, units, decimal numbers  NEW  perimeter, sides, length, base, height, oblique, vertical, right angle  STRUCTURES  I calculate…, I add…, I multiply…, Perimeter is…  FUNCTIONS  ‘will’ prediction corsista: Carmela Ruggiero 5 Communication

 IDENTIFYING  Quadrilaterals and their properties  CLASSIFYING  Regular and irregular quadrilaterals  REASONING  If… then …. corsista: Carmela Ruggiero 6 Cognition

 working in group respecting rules corsista: Carmela Ruggiero 7 Citizenship

 Web pages and interactive test  15 plastic geometric quadrilaterals  Drawing on a poster Venn diagrams  Worksheets  Worksheets for less and more able learners  Flash cards  Yardstick and measuring tape corsista: Carmela Ruggiero 8 Resources

 WHOLE CLASS  Activation of prior knowledge  Learners look around in the school garden and identify some shapes of flowerbeds  GROUPS  Put plastic geometric quadrilaterals in two different boxes: regular and irregular  Use the measuring tape to measure school objects  Draw on posters Venn diagram  INDIVIDUALLY  Calculate perimeters on their own worksheet  DIFFERENTIATION  For less able learners:  Give them practical examples and easier geometrical shapes  For more able learners:  transform calculated perimeters from decimal system into imperial system  WHOLE CLASS  Final plenary;  TPR - in the gym some learners draw by their own bodies geometrical shapes according to the teacher’s request  FOLLOW-UP  check that the calculations on the perimeter are resolved correctly corsista: Carmela Ruggiero 9 Procedure
