What are the ingredients for a good mathematics lesson? Teachers are continually faced with a range of advice or ideas to improve their mathematics lessons. It’s a little bit like recipes. New cookbooks appear on bookstore shelves, but often they’re just adaptations of recipes that have been around before, and their foundation ingredients are tried and tested, and often evidence based. There are always the staple ingredients and methods that are required for the meal to be successful.
The following is a list of what I consider to be important ingredients when planning and teaching a successful mathematics lesson. The list (or recipe) is split into two: lesson planning and lesson structure.
- Be clear about your goal. What exactly do you want your students to learn in this lesson? How are you going to integrate mathematical content with mathematical processes? (The proficiencies or Working Mathematically components)
- Know the mathematics. If you don’t have a deep understanding of the mathematics or how students learn that aspect of mathematics, how can you teach it effectively? Where does the mathematics link across the various strands within the mathematics curriculum?
- Choose good resources. Whether they are digital or concrete materials, make sure they are the right ones for the job. Are they going to enhance students’ learning, or will they cause confusion? Be very critical about the resources you use, and don’t use them just because you have them available to you!
- Select appropriate and purposeful tasks. Is it better to have one or two rich tasks or problems, or pages of worksheets that involve lots of repetition? Hopefully you’ve selected the first option – it is better to have fewer, high quality tasks rather than the traditional worksheet or text book page. You also need to select tasks that are going to promote lots of thinking and discussion.
- Less is more. We often overestimate what students will be able to do in the length one lesson. We need to make sure students have time to think, so don’t cram in too many activities.
- You don’t have to start and finish a task in one lesson. Don’t feel that every lesson needs to be self-contained. Children (and adults) often need time to work on complex problems and tasks – asking students to begin and end a task within a short period of time often doesn’t give them time to become deeply engaged in the mathematics. Mathematics is not a race!
- Begin with a hook. How are you going to engage your students to ensure their brains are switched on and ready to think mathematically from the start of each lesson? There are lots of ways to get students hooked into the lesson, and it’s a good idea to change the type of hook you use to avoid boredom. Things like mathematically interesting photographs, YouTube clips, problems, newspaper articles or even a strategy such as number busting are all good strategies.
- Introduction: Make links to prior learning. Ensure you make some links to mathematics content or processes from prior learning – this will make the lesson more meaningful for students and will reassure anxious students. Use this time to find out what students recall about the particular topic – avoid being the focus of attention and share the lesson with students. Talk about why the topic of the lesson is important – where else does it link within the curriculum, and beyond, into real life?
- Make your intentions clear. Let students know what they’re doing why they’re doing it. How and where is knowing this mathematics going to help them?
- Body: This is a good time for some collaboration, problem solving and mathematical investigation. It’s a time to get students to apply what they know, and make links to prior learning and across the mathematics curriculum. This is also a time to be providing differentiation to ensure all student needs are addressed.
- Closure: This is probably the most important time in any mathematics lesson. You must always include reflection. This provides an opportunity for students to think deeply about what they have learned, to make connections, and to pose questions. It’s also a powerful way for you, the teacher, to collect important evidence of learning. Reflection can be individual, in groups, and can be oral or written. It doesn’t matter, as long as it happens every single lesson.
There are many variables to the ingredients for a good mathematics lesson, but most importantly, know what you are teaching, provide opportunities for all students to achieve success, and be enthusiastic and passionate about mathematics!
