How to make a game to learn about integers in Scratch

Scratch can help you program Math games to help children understand the lesson better. Below is an example How to create a game to learn about integers using Scratch.

What is the integer game?

This type of game focuses on whole numbers. In this type of game, the player is required to enter a number to get the correct result.

Steps to create an integer game using Scratch

Here are step-by-step instructions for creating an integer game in Scratch:

Step 1: Create a new Scratch project

Open the Scratch editor and create a new project. You can do this by clicking the button Create on the Scratch homepage.

Step 2: Add characters (sprite) and background

In an integers game, you can use any character or background that fits your theme. For example, you can choose numbers, computers, or cartoon characters. You can also create your own background or use the available backgrounds in Scratch.

To add a character, click the button Choose a Sprite in the lower right corner of the editor, then select the character you want to use.

To add a background, click the button Choose a Backdrop in the lower right corner of the editor, then select the background you want to use.

Step 3: Create variables

To keep track of scores and target numbers, we need to create two variables. To create a variable, select the sprite as the player, click the Variables tab in the Blocks menu, then click Make a Variable. Let’s name the first variable score and the second variable target.

Step 4: Set up the game

We need to set up the game by initializing the variables and generating a random target number. First, place the character (sprite) you have chosen as the player in position. To do this, we use command blocks when green flag clicked. Let’s drag the command block set score to 0 and put it inside the command block when green flag clicked. Next, drag the command block set target to and place it right below the command block set score to 0.

To generate a random target number, use a command block pick random. Click on the card Operators in the command blocks menu, then drag the command block pick random go out. Place this command block inside the command block set target tothen set the minimum and maximum values ​​according to the range you desire.

Step 5: Create logic for the game

This step builds the logic for the game, which involves receiving input from the player and checking whether it matches the target number. To do this, select the character (sprite) acting as the player, then use the command block ask. ask (ask) to ask the player to enter a number.

Please click on the card Sensing in the menu Blocks (Command blocks) then drag the block ask. ask go out. Place this block inside when green flag clicked (when clicking on the green flag) and enter content asking the player to enter a number.

Next, we need to create a new variable called Answer (Answer) to store the value that the user enters. Then use the command block set (set) to save player input to this variable. Click on the card Variables (Variables) in the menu Blocksdrag the block set out, place it below the block ask. askthen select answer from the drop-down menu.

Now, we need to check if the data the player entered matches the target number. To do this, we use command blocks if. Click on the card Control in the menu Blocks then drag the command block if go out. Place this block below the command block setthen set up a condition to check whether the value the player enters is equal to the target number. If the player’s input matches the target number, we need to update the score and broadcast a notification. To do this, use command blocks broadcast to display a message letting the player know that they have won that round. Please click on the card Events In the Blocks menu, drag a command block broadcast out, put it inside the command block ifthen enter a message to let the player know they’ve won.

If the player’s input does not match the target number, use a command block broadcast (play message) to display a message indicating that the player has lost that round. Click on the card Events (Events) in the menu Blocks (Command block) and then pull out the broadcast block. Place this block inside the section else. else (otherwise) of the command block if (if), then enter message text to let the player know that they have lost.

After you have set up the first sprite, you need to place the second sprite in the position corresponding to the random number generated on the stage. To do this, select the second sprite and use the when green flag command block clicked. Next, from the card Controldrag the command block if go out; then, from the card Operatorsselect the corresponding conditional block and place it inside that if block. Next, from the Motion tab, drag a command block go to out and set the coordinates x and y to match your wallpaper. You will need to use multiple command blocks if same command blocks go to to set the location based on the wallpaper you selected.

Step 6: Play the game

After completing the above steps, you can start playing the game by clicking on the green flag in the upper right corner of the editor. The game will ask the player to enter a number. If the number is correct, a congratulatory message will appear, otherwise, if the answer is incorrect, the player will receive a corresponding message.

Creating an Integer Game on Scratch is a fun and engaging way to introduce children to the world of programming. This game is both interactive, challenging and entertaining, as well as educational, helping children become familiar with numbers and practice problem-solving skills through fun, exciting experiences.
