Step 1: Make it

What is it?

Test your knowledge of times tables with this project.

These two videos show you what you'll make and how to code it:

How it works

  • 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.

What you need

  • micro:bit (or MakeCode simulator)
  • battery pack (optional)
  • our set-up guide may be useful

Step 2: Code it

Step 3: Improve it

  • 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.
