You’ve been asked by the 3rd grade teacher in your school to develop a

You have been requested to create a simple program that provides third-grade students with random multiplication practice. The program should ask the student to input the lowest and highest numbers they want included in the problems, storing these inputs in variables lowEnd and highEnd. Then, the program should generate two random integers within this range, saving them in variables firstNum and secondNum. The student is prompted to submit their answer to the multiplication of these two numbers. After the student inputs their answer, the program should display the correct solution.

For example, the program will ask: "What is 3 x 7?" and once the student inputs their answer, it will show the correct product. The program should be written within a main() function and be called to run. Use string and variable concatenation in prompts to make the questions clearer. Include blank console.log() statements where appropriate to improve readability.

Sample Paper For Above instruction

Below is an example implementation of the described program in JavaScript, suitable for educational purposes in a third-grade setting. The program uses functions to handle input and output, incorporates random number generation within a specified range, and provides feedback to the student.

JavaScript Implementation of a Simple Multiplication Practice Program

function main() {

// Ask the student for the lowest number to include in the multiplication problems

const lowEnd = parseInt(prompt("Enter the lowest number for multiplication:"));

// Ask the student for the highest number to include

const highEnd = parseInt(prompt("Enter the highest number for multiplication:"));

// Generate two random integers within the specified range

const firstNum = Math.floor(Math.random() * (highEnd - lowEnd + 1)) + lowEnd;

const secondNum = Math.floor(Math.random() * (highEnd - lowEnd + 1)) + lowEnd;

// Prompt the student to answer the multiplication question

const userAnswer = parseInt(prompt(firstNum + " x " + secondNum + " = ?"));

// Calculate the correct answer

const correctAnswer = firstNum * secondNum;

// Provide feedback

console.log(); // blank line for readability

if (userAnswer === correctAnswer) {

alert("Correct! Well done!");

} else {

alert("Oops! The correct answer is " + correctAnswer + ".");

}

}

// Call the main function to run the program

main();

This implementation follows the specified instructions: it collects user input for range boundaries, generates random numbers within the range, prompts the student for an answer, and then displays the correct answer. This tool can be expanded with multiple questions or score tracking for extended practice.
