An Inquiry Maths lesson
Seven components of mathematical inquiry
Inquiries that develop from the same prompt can follow very different pathways. They might last one lesson or extend over a series of lessons and might involve students in working collaboratively on one line of inquiry or individually on multiple lines. Nevertheless, the teacher should bear in mind the following seven components of mathematical inquiry when navigating a lesson.
1. Orientation to the prompt: questioning, noticing and wondering
The teacher invites pairs of students to make an observation or pose a question about the prompt, providing the class with stems (examples below) if appropriate.

2. Establishing aims and planning actions
The teacher reviews the questions and observations (perhaps 'thinking aloud') and might take the opportunity to comment on possible lines the inquiry. Students participate in directing the inquiry by selecting a regulatory card - a selection that is then justified in a class discussion.
Students might decide on a period of exploration when they aim to generate more examples or find a case that satisfies the condition in the prompt. At the end of this period, they might have formed a generalisation through induction.
4. Teacher or student explanation
Students might identify an impasse that can only be overcome with new conceptual or procedural knowledge. Their request for an explanation might lead to a whole-class episode when knowledge is shared or constructed collaboratively. Alternatively, the teacher might encourage small-group instruction (led by the teacher or a student).
5. Explaining and proving
Students prove a conjecture or generalisation they have made earlier in the inquiry. They reason deductively, perhaps with formal algebra or through a structural analysis of a mathematical model.
6. Presenting results
Students present their results in written or other forms. The teacher often calls on students to present their work in progress or suggest new ideas and directions to the class.
7. Reflecting and evaluating
The teacher leads students in reflecting on the course of the inquiry, and in evaluating how successfully the class has resolved the questions posed at the beginning.
Elements more than steps
Inquiry Maths lessons are responsive to students' questions and observations about the prompt. The seven components of mathematical inquiry are, therefore, not intended to be seen as a linear process in which each component follows on from the one before in strict order. Rather, as Kath Murdoch says in The Power of Inquiry, the parts are "phases more than they are stages, elements more than they are steps." For example, the teacher should promote questioning throughout the inquiry, not just at the beginning. In this way, students deepen their initial questions and generate more lines of inquiry.
However, the Inquiry Maths model is built on Polya's view of mathematics as a process in which deduction 'completes' induction.
Polya's description suggests mathematical inquiry is linear, advancing from inductive exploration to deductive reasoning. While this might be the general trend, the relationship between the two is not necessarily linear. Inquiries can zig-zag between induction and deduction when, for example, students use empirical tests to amend deductive arguments. Students can also use algebraic or structural reasoning from the start and extend the inquiry by changing the properties of the prompt.
What level of inquiry should you plan? What is the profile of your class? Would your students learn best through a structured, guided or open inquiry? How much structure does the class need in each of the different phases of the inquiry?
Ten frequently asked questions
1. Can you expect students to inquire without being given content knowledge beforehand?
Yes. Inquiry provides a meaningful context to learn content and empowers students to make decisions about how they use that content. Inquiry lessons do not preclude the 'transfer' of knowledge. If students identify a need for new conceptual or procedural knowledge to make progress during an inquiry, the teacher is responsible for making it available. Moreover, if students request an explanation, they are more likely to be motivated to listen and engage actively with what the teacher or another student says.
2. Can you expect students in bottom sets to take part in inquiry?
Yes. All students deserve the opportunity to experience the excitement of inquiry. Often students are in bottom sets because they do not have the higher order skills required to regulate learning. Inquiry Maths gives all students the opportunity to develop those skills. Moreover, it is not the case that attainment in mathematics can be used to predict an inquiry disposition. Students with higher prior attainment in the subject can be more anxious about inquiry because they are likely to have achieved their 'success' in traditional classrooms by answering repetitive exercises.
3. What happens if the students don't ask any questions at the start of the inquiry?
Three steps make this highly unlikely: firstly, set the prompt just above the understanding of the class to engage students' natural curiosity; secondly, structure the questions and observation phase by providing appropriate stems; and, thirdly, praise all mathematical contributions and return to them as they arise during the inquiry, acknowledging the author as you do so. In the event of not receiving any questions, probe students' understanding of the prompt and proceed with a teacher-directed, structured inquiry.
4. Isn't learning through inquiry too slow to cover the curriculum?
Inquiries might seem to start slowly, but the construction of a shared understanding in the first phase leads to a deeper understanding of procedures and concepts later in the inquiry. Indeed, it is essential that inquiries start slowly to ensure the involvement of everybody in the inquiry. Students are often more motivated to learn when answering their own questions and, consequently, their learning is faster and more memorable than in normal lessons.
5. How can you be sure that the students meet lesson objectives during inquiry lessons?
The inquiries on the Inquiry Maths are linked to standard curricular objectives. As the teacher monitors the mathematical validity of students’ aims during inquiry, objectives will be met even if they are not in the order prescribed in a scheme of learning. Moreover, inquiries integrate concepts from different areas of mathematics, making the subject more connected and meaningful (as opposed to being viewed as a list of discrete objectives). It is also often the case in inquiry lessons that students will challenge themselves to meet objectives at a higher level than expected in pursuit of answers to their own questions.
6. How often should you use inquiries?
The frequency of inquiries depends on your national or state curriculum. In England, for example, inquiry encompasses one of the three aims of the National Curriculum. So a third of lessons, it could be argued, should be based on the processes of mathematical inquiry. Furthermore, students will become fluent in applying procedures (another aim of the curriculum) during inquiry, so the fraction could justifiably be more than a third. It is our contention that the whole curriculum could be taught through inquiry, but that might not be possible because of departmental, school or curricular restrictions.
7. Isn't inquiry too unpredictable for inexperienced teachers?
The potentially unpredictable nature of inquiry can be a concern for all teachers, not just for those who are newly qualified. Students need to be trained to be inquirers. Teachers new to inquiry should take small steps, building up to open inquiry over months and years, rather than weeks. You could open up the start of the lesson for students’ questions and observations about the prompt, then use a pre-planned structure for the rest of the inquiry. In subsequent inquiries, you could give students the choice of more than one pathway to follow before encouraging them to devise and pursue their own ideas.
8. Isn't it too difficult for individual teachers to use inquiry on their own?
Sometimes it is hard to go it alone in a department that promotes teacher transmission and student performance. However, when you try inquiry, you might find unexpected interest from colleagues who themselves are looking for ways out of the sterile traditional model of teaching. Students who are used to repetitive practice are likely to find the thinking processes associated with inquiry challenging at first. Use a structured approach in your first attempts.
9. What prompt should I choose to get started?
Inquiry Maths prompts are designed around concepts in the school curriculum. You might start by choosing a prompt linked to the topic in your scheme of learning. However, the prompts on the website will not suitable for all classes and should not be simply 'taken off the shelf'. The prompts should be adapted to sit just above the understanding of the class, thereby promoting curiosity.
An example comes from a secondary school maths department that was using the percentages prompt. The prompt on the website would have provided little intrigue for the highest set and would have been too challenging for the lowest. So the teachers adapted the prompt for their own classes as shown in the table.
10. How can you make inquiry more accessible?
This question comes from Alex Zisfein, a secondary teacher of mathematics in New York City, who felt the prompts are more suitable for advanced classrooms, rather than for general education groups. There are two ways to make the prompts more accessible Firstly, the teacher can take more responsibility for structuring the inquiry by, for example, preparing a pathway for students to follow in the first lesson and then planning subsequent lessons that respond to the students’ questions and observations. Secondly, prompts can be adapted to ensure they are both familiar and unfamiliar. Familiarity gives students confidence to analyse and transform the prompt; unfamiliarity generates curiosity to understand the prompt more deeply.
Structures of mathematical inquiry
The 4D-cycle of mathematical inquiry
The inquiry cycle was devised by Professor Katie Makar (University of Queensland). Each part of the cycle is described in more detail on this page from Thinking through Mathematics. Additional information appears in Professor Makar's 2012 chapter 'The Pedagogy of Mathematics Inquiry'* and on the IMPACT website.* In Gillies, R. M. (Ed.). Pedagogy: New Developments in the Learning Sciences. New York: Nova Science Publishers, pp. 371-397.
One aim of the IB diploma programme for mathematics is to promote inquiry approaches in which students "investigate unfamiliar situations, both abstract and real-world, involving organising and analysing information, making conjectures, drawing conclusions and testing their validity." In order to achieve the aim, teachers are encouraged to use the flow chart when planning inquiry lessons.
Language acquisition as the first phase of inquiry
Sonya terBorg blogged about using Inquiry Maths prompts with her primary class in Idaho (US). Her post describes how the class carried out a preliminary inquiry into concepts and language related to angles. The pupils then conducted an open and collaborative inquiry into the prompts by applying the language acquired earlier.
Inquiry Maths lesson structure
The lesson structure was developed in a community of teachers from different subject areas who were studying inquiry teaching. The school had 100-minute lessons, which explains the scale on the left. After the initial responses to the prompt, the teacher is expected to structure the inquiry by putting the students' questions in order.
An alternative lesson structure
This diagram of a lesson structure was devised by Satvia Bahia (a secondary school mathematics teacher) for a presentation about Inquiry Maths that she was giving to trainee teachers. It shows the teacher deciding on the level of structure (for individual students or the whole class) as the inquiry progresses, although the decision about the type of inquiry might have been taken before the lesson based on the profile of the class.

Maths inquiry template
Amelia O'Brien, a grade 6 PYP teacher at the Luanda International School (Angola), has shared her Mathematics Inquiry Template with Inquiry Maths. The template helps students think about concepts relevant to the prompt and plan the inquiry. In their most recent inquiry, Amelia's pupils posed generative questions that opened up new pathways for inquiry (see a report here under the title 'Question-driven inquiry').
