Mathématiques – Extraklass

Junior Mathematicians: patterns, codes and impossible shapes

In this session, children find the maths hidden in secret codes, dice, flowers and shapes that seem impossible. The instructor brings every material, including snap cubes, dice, real pinecones and flowers, so the school has nothing to prepare.

Each session is built around one maths idea. The instructor explains it, and the children test it themselves in two or three hands-on activities. The 1 hour session, Marvellous Magical Maths, covers number tricks and secret codes. The 2 hour session adds Mother Nature’s Secret Math Code, on the Fibonacci sequence in plants. The 3 hour session adds Crazy Shapes, on strange shapes like the Möbius strip.

Junior Einsteins Science Club® is an award-winning programme. This session enriches the Mathématiques domain of the plan d’études in cycles 1 to 4, with a focus on numbers, patterns, space and shapes, and problem solving.

Learning objectives

Marvellous Magical Maths

Children can use a finger trick to find the answers in the nine times table.
Children can encode and decode a message with a simple shift code.
Children can explain that a code follows a fixed set of steps.

Mother Nature’s Secret Math Code

Children can continue the Fibonacci sequence by adding the two numbers before.
Children can count the petals on a flower and record them on a tally sheet.
Children can find the Fibonacci numbers in the spirals of a pinecone.

Crazy Shapes

Children can explain that a Möbius strip has only one side and one edge.
Children can predict and test what happens when a Möbius strip is cut.
Children can draw an impossible triangle and explain why it can’t exist.

Dir schafft am Cycle 3 an hutt Loscht, mat Äre Kanner den DASH Roboter ze entdecken a flott Missiounen zesummen ze kodéieren? Da sidd Dir hei genee richteg, a keng Angscht, Dir braucht och keng Erfarung am Kodéieren ze hunn. Dofir gëtt Iech am Ufank vum Schouljoer eng Formation continue ugebueden.

Hautdesdaags ass et essentiel, datt all Schüler d’Méiglechkeet kritt, d’Basiskonzepter vun der Informatik ze verstoen a se ze benotzen, fir Problemer ze léisen. Eng Robotik-Aktivitéit entwéckelt Fäegkeeten am logeschen Denken, Problemléisen, Teamwork a am Beräich vun der Kreativitéit. Et sinn dës interdisziplinär Fäegkeeten, déi och zentral an de Beräicher Mathematik, Naturwëssenschaften, Sproochen, asw. sinn.

Wärend der Challenge entdecken d‘Kanner den DASH Roboter, seng villfälteg Funktiounen, maachen éischt Schrëtt an der block-baséierter Kodéiersprooch a léisen am Team erausfuerderend Challengen op eng kreativ Aart a Weis.

Mat e bësse Geschéck qualifizéiert Är Klass sech fir déi grouss Finall, wou Är Kanner d’Méiglechkeet gebuede kréien, hire Roboter an hir Kodéier-Fäegkeeten engem breede Public virzestellen.
