1. Core Concept and Purpose:

Both sources describe a digital adaptation of the traditional Snakes and Ladders game designed as an educational tool for young students. The primary purpose of this game is to:

• Develop a visual understanding of addition and subtraction concepts: The movement on the board, influenced by dice rolls and the effects of snakes and ladders, directly reflects adding or subtracting numbers.
• Familiarize students with numbers from 1 to 100: The game board provides a visual representation of the number sequence within this range.

The game is explicitly linked to a "jump" strategy for addition and subtraction, although the mechanics of this strategy are not detailed within these excerpts. The title of the first source, "Snake and Ladder Game for Add and Subtract within 100 using ‘Jump’ strategy," highlights this pedagogical approach.

2. Game Mechanics and Features:

The HTML5 Javascript applet, described in the second source, provides a concrete implementation of this educational game. Key features include:

• Support for 2-6 players: This allows for collaborative or competitive learning environments.
• Option for 1 or 2 dice: This introduces variability in the magnitude of addition or subtraction, potentially catering to different learning paces or increasing complexity.
• Traditional Snakes and Ladders elements:Ladders: Landing on a ladder square allows players to "skip squares," representing a larger addition.
• Snakes: Landing on a snake square forces players to "go back squares," representing subtraction.
• Dice Icon Squares: Landing on these allows for an additional roll, adding an element of chance and further practice with addition.
• Switchable Addition and Subtraction Modes: This is a crucial pedagogical feature.
• Addition Mode: Players move from 1 to 100.
• Subtraction Mode: Players move from 100 to 1. This provides a direct parallel and reinforces the inverse relationship between the two operations. The second source explicitly states: "The difference between the 2 modes is that the former has the players going from 1 to 100, while the latter has the players going from 100 to 1."
• Objective: The goal remains the same as traditional Snakes and Ladders: to be the first player to reach the end of the board (100 in addition mode, 1 in subtraction mode).

3. Authorship and Development:

Both sources credit the development of the game to:

• Shaun Quek
• Loo Kang Wee
• Francisco Esquembre
• Félix Jesús Garcia Clemente
• Based on an idea by Yah Hui Tan

The first source also mentions that it was "Compiled with EJS 6.1 BETA (201115)," indicating the software used for its creation. The second source identifies the applet as part of the "Open Educational Resources / Open Source Physics @ Singapore" initiative, emphasizing its accessibility and potential for wider use.

4. Educational Value and Target Audience:

The sources clearly state that the game is intended to help "young students" gain a visual understanding of addition and subtraction and become familiar with numbers up to 100. The interactive nature of the game is intended to make learning engaging and enjoyable.

5. Accessibility and Usage:

The second source provides an embeddable iframe code, indicating that the applet can be easily integrated into webpages. It also provides a direct link to run the game: "The link to the game can be found here .". This highlights the accessibility of the resource for both educators and students.

6. Licensing and Usage Rights:

The first source explicitly states the copyright and licensing information: "© 2021, Shaun Quek; Loo Kang Wee; Francisco Esquembre; Félix Jesús Garcia Clemente; based on idea by Yah Hui Tan. Compiled with EJS 6.1 BETA (201115) Released under a license." The second source, under the "Open Educational Resources / Open Source Physics @ Singapore" banner, mentions that "Contents are licensed Creative Commons Attribution-Share Alike 4.0 Singapore License." This suggests the resource is openly available for use and adaptation under certain conditions. It also includes a separate note regarding commercial use of the EasyJavaScriptSimulations Library, directing users to the specific license and contact information.

7. Connection to Broader Resources:

The extensive list of other resources in the second source suggests that this "Snake and Ladder Game" is part of a larger collection of interactive mathematics and science applets developed and shared by the Open Educational Resources / Open Source Physics @ Singapore initiative. This context highlights a commitment to providing educators with a wide range of freely accessible learning tools.

In conclusion, the "Snake and Ladder Game for Add and Subtract within 100 using ‘Jump’ strategy" is presented as a valuable educational resource for young learners. Its digital implementation as an HTML5 Javascript applet offers an engaging and interactive way to visualize addition and subtraction concepts within the number range of 1 to 100. The game's features, including adjustable player numbers, dice options, and switchable operation modes, enhance its pedagogical utility. Its open licensing and accessibility further contribute to its potential as a widely adopted learning tool.

Frequently Asked Questions: Snake and Ladder Game for Addition and Subtraction

1. What is the purpose of the "Snake and Ladder Game for Addition and Subtraction"? The primary purpose of this digital game, modeled after the traditional Snakes and Ladders, is to help young students visually understand the concepts of addition and subtraction. It also aims to familiarize them with numbers from 1 to 100 in an engaging and interactive way.

2. How does the game work? Players take turns rolling one or two virtual dice (the option can be chosen). The number rolled determines how many squares the player moves on the game board. The objective is to be the first player to reach the end of the board.

3. What are the special features on the game board? The game board includes squares with special icons that trigger automatic effects when a player lands on them: * Ladders: Allow players to advance to a higher square, effectively skipping some squares. * Snakes: Force players to move back to a lower square. * Dice: Grant the player an extra roll of the dice.

4. What are the different game modes available? The game offers two distinct modes: * Addition Mode: Players progress from square 1 towards square 100. * Subtraction Mode: Players start at square 100 and move towards square 1. This mode helps visualize subtraction as moving backward on the number line.

5. How many players can participate in the game? The game is designed to support between 2 and 6 players, making it suitable for small group activities or individual play.

6. Who developed this game and under what license is it released? The game was developed by Shaun Quek, Loo Kang Wee, Francisco Esquembre, and Félix Jesús Garcia Clemente, based on an idea by Yah Hui Tan. It is released under a Creative Commons Attribution-Share Alike 4.0 Singapore License, which promotes sharing and adaptation with appropriate credit. The underlying Easy JavaScript Simulations (EJS) library has a separate commercial use license that requires contacting fem@um.es.

7. Is this game available online, and how can it be accessed? Yes, the game is available online as an HTML5 Javascript applet. It can be embedded in webpages using an iframe, and a direct link to run the game is provided: https://iwant2study.org/lookangejss/math/ejss_model_Board_Game_1to100/.

8. What are some potential learning goals or educational applications of this game for teachers? This game can be a valuable tool for teachers to: * Provide a visual and interactive way for young learners to grasp addition and subtraction within 100. * Help students become more familiar with the sequence and magnitude of numbers up to 100. * Offer a fun and engaging activity that reinforces basic arithmetic skills. * Serve as a supplementary resource for mathematics lessons focusing on number sense and operations.
