As more schools across the country begin emphasizing the importance of STEM education and preparing students for college and career readiness in the fields of math and science, teachers are looking for innovative ways to engage young learners. One area that has gained a lot of attention lately is the concept of translations of functions. A translation is a movement of a graph along the x and/or y-axis, either up, down, left, or right, without changing its general shape. By incorporating these activities into your lesson plans, you can help students understand the meaning of these translations and deepen their understanding of functions. Here are a few activities to get you started:
1. Graph translations scavenger hunt: This activity is perfect for kinesthetic learners and groups of students working together. Create multiple sets of graphed functions, each with a different translation. Cut each graph into several pieces and mix them up. The students’ task is to find the matching translation of each graph and put them back together. The first team to put all of their graphs together wins.
2. Describing translations: In this activity, students will work in pairs to translate a graph and then describe that translation to their partner. Provide pairs of students with the same function, and instruct one to move the graph up or down, and the other to move it left or right. Each pair then describes their new graph to the other, explaining how they moved it.
3. Coordinate plane game: Create a coordinate plane on the classroom floor, using masking tape or painter’s tape. Choose a starting point for each student and have them take turns rolling dice that will tell them how to translate their point. For example, if they roll a four, they must move their point four units to the right. As they move around the graph, have them take note of what happens to their previous points and how the overall function is being translated.
4. Translation flashcards: Create sets of flashcards with functions on one side and translations on the other. Students can work independently or in pairs to match the translation with the correct graph. Have them discuss their answers and explain why they made certain choices.
5. Writing translation rules: After students have had several opportunities to practice translating functions, have them create their own rules for how to translate graphs. They can use these rules to create their own functions and translate them accordingly. This is also a good opportunity to reinforce the importance of precise language and mathematical notation.
By utilizing these activities and others like them, you can help students develop a strong understanding of translations of functions and deepening their overall understanding of math. Helping students see the real-world applications of math beyond the classroom is one key to engaging and preparing them for their future careers.
