Problem Description:
The image shows three game boards related to a math activity. The task involves solving a problem based on the content of these boards. Let's break it down step by step:
#### Board 1: "MAKE A WORD"
- This board contains a grid with numbers and letters. Each number corresponds to a letter.
- The goal is likely to use the numbers to spell out words by matching them with the corresponding letters.
#### Board 2: "FOUR IN A ROW"
- This board is labeled "Four in a Row: 3-digit addition."
- It involves rolling two dice, one for each column, and adding the resulting numbers.
- The player marks the answer on the board.
- The objective is to get four squares in a row (horizontally, vertically, or diagonally).
#### Board 3: "ROLL"
- This board has spaces for recording rolls and sums.
- It appears to be a worksheet for tracking the results of the dice rolls and their sums.
Task Analysis:
The task seems to involve using the "Four in a Row" game to practice 3-digit addition. Players roll two dice, add the numbers, and mark the result on the board. The goal is to achieve four in a row.
Solution Approach:
1. Understanding the Dice Rolls:
- Each die has numbers from 1 to 6.
- When rolling two dice, the possible outcomes range from \(1 + 1 = 2\) to \(6 + 6 = 12\).
- However, the board shows sums that are much larger (e.g., 797, 879, etc.). This suggests that the dice rolls are being used as indices to select numbers from the board.
2. Interpreting the Board:
- The "Four in a Row" board has numbers in a grid format.
- Each cell contains a 3-digit number.
- The instruction mentions rolling two dice, one for each column. This implies:
- The first die determines the column.
- The second die determines the row.
- The intersection of the chosen column and row gives the number to be added.
3. Example Calculation:
- Suppose you roll a 3 on the first die and a 4 on the second die.
- You would look at the number in the 3rd column and 4th row.
- From the board, the number in the 3rd column and 4th row is 730.
- Mark this number on the board.
4. Achieving "Four in a Row":
- Continue rolling the dice, selecting numbers, and marking them on the board.
- The goal is to get four marked numbers in a row (horizontally, vertically, or diagonally).
5. Recording Rolls:
- Use the "ROLL" worksheet to keep track of each roll and the resulting sum.
- This helps in organizing the gameplay and ensures no mistakes are made.
Final Answer:
The solution involves playing the "Four in a Row" game by:
1. Rolling two dice.
2. Using the dice rolls to select a number from the grid.
3. Marking the selected number on the board.
4. Repeating the process until you achieve four in a row.
The key is to carefully follow the instructions and use the provided boards effectively.
Final Answer: \boxed{\text{Play the "Four in a Row" game by rolling two dice, selecting numbers from the grid, and marking them on the board to achieve four in a row.}}
