Das Üben am eigenen Handy kommt bei einzelnen und Lerngruppen bestens an. Ebenso kann mit schlau.app - da es eine Web-App ist - am digitalen Whiteboard im Klassenraum gearbeitet werden.

&lt;a href=&quot;https://youtu.be/AnDeFZM2-5Q?si=iCAYRyj1nBxtERwN&quot;&gt;In 4 Levels sicherst du&lt;/a&gt; deine erfolgreiche BBR- oder MSA-Prüfung. Wer die Levels 1 bis 4 wirklich beherrscht und dazu ein paar typische Anwendungsaufgaben zur BBR-/MSA-Prüfung in Mathe trainiert, kann praktisch nicht mehr durchfallen.

Level 1, Button -a + b Plus und Minus auf dem Zahlenstrahl: das flüssige Rechnen mit positiven und negativen Zahlen ist absolut notwendig für praktisch alle Mathethemen der Mittelstufe und BBR/MSA-Prüfungen in Mathe. https://schlau.app/?atype=add

Level 2, Button a -(-+b) Plus und Minus mit Klammern: hier kommen Klammern hinzu. Diese Aufgaben schriftlich bearbeiten und jeweils die Schritte sauber untereinander oder auch nebeneinander aufschreiben. https://schlau.app/?atype=addsub

Level 3, Button x + a = b Plus-Minus-Umstellen, nach x auflösen. Dieser Rechenvorgang gehört wie die beiden o.a. Zahlenstrahl-Vorgänge zu den absoluten Basics und ist quasi deren Fortsetzung. Genau wie Plus-Minus-Rechnen mit Klammern sollten hier alle Schritte schriftlich gemacht werden. https://schlau.app/?atype=lin1

Level 4, Button a ⋅x = b. Mal-Geteilt-Gleichungen, nach x auflösen. So wie das Thema Proportion-Anteil-Dreisatz, s.u., ein inhaltliches Kernthema der Mittelstufe ist, so sind die Umformungen vom Typ.&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;https://youtu.be/AnDeFZM2-5Q?si=iCAYRyj1nBxtERwN&lt;/p&gt;</content><link rel='replies' type='application/atom+xml' href='http://deutschlandurlaub.blogspot.com/feeds/1366217895688683497/comments/default' title='Kommentare zum Post'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment/fullpage/post/6877180101953219222/1366217895688683497' title='0 Kommentare'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6877180101953219222/posts/default/1366217895688683497'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6877180101953219222/posts/default/1366217895688683497'/><link rel='alternate' type='text/html' href='http://deutschlandurlaub.blogspot.com/2024/02/mathe-bbr-und-msa-die-grundlagen-sicher.html' title='Mathe BBR und MSA.

Jahrhundert - es war die Zeit der Aufklärung mit sehr vielen Entdeckungen - hat Charles du Fay mit ganz ähnlichen Rubbel-Experimenten die zwei Arten der Elektrizität gefunden.

Übe das einfach! Und mache dir auch klar, warum es funktioniert. Dadurch lernst du eine Menge, nämlich zum Thema Brüche erweitern und kürzen.

Denn wir müssen nur die Fläche eines Rechtecks wissen, um die Konstruktion zu verstehen. Gedankengang: 1) Fläche eines Rechtecks mit Grundlinie (Länge) a und Höhe (Breite) h ist: A = g ⋅ h 2) Fläche eines Parallologramms mit gleicher Grundlinie g und gleicher Höhe h ist ebenfalls A = g ⋅ h 3) Wir zeigen, dass das Parallelogramm aus zwei gleichen Dreiecken besteht. Diese haben ebenfalls die Grundlinie g und Höhe h. Damit sehen wir, dass die Fläche eines der Dreiecke die Hälfte sein muss: Die gesuchte Dreiecksfläche ist g ⋅ h / 2 oder auch (1/2) ⋅ g ⋅ h&lt;/span&gt;&lt;/p&gt;&lt;p&gt;https://youtube.com/shorts/NvUMCKQxh0A?si=89JeiFyK8cur_iwE&lt;/p&gt;</content><link rel='replies' type='application/atom+xml' href='http://deutschlandurlaub.blogspot.com/feeds/8905143273808847553/comments/default' title='Kommentare zum Post'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment/fullpage/post/6877180101953219222/8905143273808847553' title='0 Kommentare'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6877180101953219222/posts/default/8905143273808847553'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6877180101953219222/posts/default/8905143273808847553'/><link rel='alternate' type='text/html' href='http://deutschlandurlaub.blogspot.com/2023/11/die-flache-eines-dreiecks-bestimmen.html' title='Die Fläche eines Dreiecks bestimmen.
