Starting a Number Talk in Kindergarten
To begin a number talk in kindergarten, it is important to create an engaging and supportive environment where students feel comfortable sharing their mathematical thinking. Here is a step-by-step guide on how to start a number talk in kindergarten:
1. Set the stage: Start by explaining to the students that you are going to have a “math talk” where everyone will have the opportunity to share their ideas and strategies for solving a math problem. Emphasize that there are no right or wrong answers, and all ideas are valued.
2. Choose the problem: Select a math problem that is appropriate for kindergarten level. The problem should be simple enough for students to mentally solve and encourage multiple strategies. For example, you might choose a problem like, “There are 5 apples. If I eat 2, how many apples are left?”
3. Present the problem: Write the problem on the board or display it on a document camera. Read the problem aloud to the students, allowing them time to think about the question. Encourage them to mentally solve the problem without using manipulatives or paper and pencil.
4. Think time: Give students a moment to think about the problem individually. This allows each student to form their own strategy and answer before sharing with the class. It is important to give enough think time to ensure that all students have a chance to engage in the problem-solving process.
5. Share strategies: After the think time, ask students to share their strategies for solving the problem. Encourage students to explain their thinking in words or drawings. As they share, make sure to validate and acknowledge each strategy, even if it differs from the traditional algorithm. This helps build a positive and inclusive classroom environment.
6. Record strategies: As students share their strategies, write them down on the board or chart paper. This allows the class to visually see the different ways of solving the problem. It also provides a reference for future discussions and reinforces the idea that there are multiple ways to approach a math problem.
7. Discuss and compare strategies: Once several strategies have been shared, facilitate a discussion comparing and contrasting the different approaches. Encourage students to explain why they chose their strategy and how it connects to other strategies. This promotes mathematical discourse and helps students deepen their understanding of mathematical concepts.
8. Summarize and connect: As the number talk comes to a close, summarize the different strategies that were shared and highlight any connections or patterns that emerged. This helps students see the big picture and reinforces the idea that math is a flexible and creative subject.
By following these steps, you can start a number talk in kindergarten that fosters critical thinking, builds mathematical understanding, and promotes a positive classroom culture. Remember to create a safe and supportive environment where all ideas are valued, and encourage students to take risks and share their mathematical thinking.
