## Cam 1: Gwneud

### Beth yw e?

Test your knowledge of times tables with this project.

Mae'r ddau fideo hyn yn dangos i chi yr hyn y byddwch yn ei greu a sut i'w godio:

### Sut mae'n gweithio

• The program uses two variables called “a” and “b” to store random numbers.
• Variables store numbers or values that can change in a computer program.
• Press button A to generate a random number between 1 and 12 for the variable “a” and to show it on the LED display. Press button B to generate another random number between 1 and 12 for “b” and to show it on the LED display.
• Shake the micro:bit to find out what the product is - that's what the answer would be if the numbers were multiplied together. This part of the program works using the multiplication block from the maths menu in MakeCode.
• You can use this project in a competitive two-player game, where the two random numbers are read out and each player must shout out the correct answer first to win a point.

### Beth sydd ei angen arnoch

• micro:bit (neu efelychwr MakeCode)
• pecyn batri (opsiynol)
• our set-up guide may be useful

## Cam 2: Codio

### Cam 3: Gwella

• Adjust the program so that it helps you to learn square numbers.
• If you are playing the two-player game, create another program on a different micro:bit to keep track of the players' scores.
• Use various inputs in this program to trigger different sound effects, which you can play when players give a correct or incorrect answer.
