# Easter Egg Sudoku Logical Reasoning Puzzle

This Easter Egg Sudoku activity is a way to introduce kids as young as preschool to the rules and the use of logical reasoning to solve a problem.

Sudoku is a great activity to strengthen logical reasoning skills and decomposition skills while working with a simple algorithm, or a series of instructions for solving problems.

## Computational Thinking Concepts

Computational thinking is a new way of problem solving that involves thinking about a problem in a way that can be solved by using computing tools like logic, decomposition, abstractions, algorithms, patterns, data collection and analysis, and simulation or modeling.

Computational thinking can be used to solve problems in almost all areas of our lives and helps kids develop some pretty great life skills that can apply to a variety of situations.

A computational thinker approaches problems by:

• Experimenting and playing to solve a problem that might have more than one possible solution
• Working together with others to reach a common goal
• Persevering when faced with a difficult problem
• Finding and fixing errors in complex problems
• Designing and making solutions for open-ended problems
• Understanding their own strengths and weaknesses

## Logical Reasoning

Logical reasoning is the ability to analyze and make predictions about things or explaining why something is the way that it is.

Easter Egg Sudoku is a great puzzle to use to emphasize the concept of logical reasoning by explaining why an egg cannot go in a certain space. Due to the rules of the puzzle, kids can speak to why each block is not certain egg colors, which helps them to identify the solution.

## How to Play Easter Egg Sudoku

This activity is most effective when it is modeled by an adult or older sibling before starting. For example, solve one block space and explain why the square can’t certain eggs.

Repeat the process for columns and rows as well as squares. Use the following rules to reference when modeling your logical reasoning.

1. Each Easter egg color can only appear once in each row
2. Each Easter egg color can only appear once in each column
3. Each Easter egg color can only appear once in each 2X2 block

### Use an Algorithm to Solve Your Easter Egg Sudoku Puzzle

An algorithm is a series of instructions to solve a problem. Begin with teaching the rules of Sudoku. You can turn these rules into an algorithm that automates how you are solving each square.

Repeat your algorithm over and over again. Think about how this process starts with a series of steps and evolves into a program that is written for a computer to automate a task. Sudoku like a robot! For example,

1. Choose square
2. Check row for Easter egg color
3. Check column for Easter egg color
4. Check box for Easter egg color

### Use Decomposition to Simplify Your Easter Egg Sudoku Puzzle

Decomposition is the process of breaking down a complex problem into smaller, easier to solve, pieces. Focus on each 2X2 grid. Try to solve each square by using the Easter egg colors in the block and following rule #3.

Another way to use decomposition (my personal favorite!) is to work on one letter at a time. For example, start with the purple egg and work your way through the rest of the colors.

## Easter Egg Sudoku for Preschoolers to 3rd Grade

Use the Easter Egg pieces to solve this Sudoku worksheet with your preschool through 3rd grade kiddo. Remember to model the logical reasoning process.

For example, solve one block space and explain why the square can’t be a certain color egg. Repeat the process for columns and rows as well as squares.

The worksheet download contains printable Easter egg pieces that you can cut out to use again and again with your puzzle as well as an answer sheet and blank grid for you to create your own puzzles.

For a fun twist, you can even use plastic Easter eggs to complete your puzzles!!
