ACTIVITY INSTRUCTIONS

Activate Schema: Based on what vocabulary we know so far, what does multiplication, array, and division mean? Multiplication: Equal groups Division: Separating groups Array: A method of showing the total of two numbers by using rows and columns. Today we will be using a microbit to demonstrate one multiplication, division, and array example! Questions: -What is a microbit? -How can a microbit be used to show multiplication, division, and array images?

Process: Airplay or Cast your computer screen to show the steps and the process using microbit MICROBIT PROJECT STEPS: You will use the tabs: Basic, Input, and Math On start Show string “Hello” Pause 2000 ms Show Icon X (stands for multiplication in this sequence) Clear Screen Show string “7 x 8” Pause 5000 ms Clear screen Show number (7x8) the number 56 will appear Pause 5000 ms Clear screen Show string “56/8” Pause 5000 ms Clear screen Show string “56/8” the number 7 will appear Download Click and Drag onto USB desktop

ARRAY MICROBIT PROJECT STEPS: You will use the tabs: Basic, Input, Math, Array On start Show string “hello” Clear Screen Show image: 4x4 array Pause 5000 ms Clear screen Show string “4 x 4” Pause 5000 ms Clear screen Show number 16 Download Click and Drag onto USB desktop

Unplugged Version: Have students create arrays that match basic multiplication and division equations on paper or with other manipulatives.
