What type of ques4ons?

When you think about the Bingo game, what types of quesFons were asked? What student understanding would be evident in the game? Talk in your group and describe the focus of the quesFons.

Ques4oning Techniques

  • Factual quesFons

comprise the majority of quesFons asked in a mathemaFcs class

– More than 145 quesFons in 48 minute class period – Less than 2 seconds for response

Ques4ons to Promote Problem Solving and Generaliza4ons

  • Reversibility quesFons:

– Promote the ability to think in different ways – Give the answer, students create the problem

Ques4ons to Promote Problem Solving and Generaliza4ons

  • GeneralizaFon quesFons:

– Ask students to find and describe pa^erns – What pa^erns do you noFce?

Ques4ons to Promote Problem Solving and Generaliza4ons

  • Flexibility quesFons:

– Ask students to solve a problem in mulFple ways OR to use what they know about one problem to solve another one – Solve the problem in another way – How are these soluFons alike? How are they different?

Your turn

Select a lesson in your text. Write two reversibility, flexibility, and generalizaFon quesFons for the lesson. OR Write two reversibility, flexibility, and generalizaFon quesFons related to a problem set that is focused on problems such as:

Three types of ques4ons

  • Exploring: underlying

mathemaFcal relaFonships and meanings

  • Probing: gecng students

to explain their thinking

  • GeneraFng: moFvaFng

discussion

What other types of ques4ons can be used?

Use the descripFon of Ms. Quigley’s class.

  • Find different types of quesFons that she

uses in her class.

  • What are the purposes of the quesFons?
  • What do they accomplish?

What types of ques4ons are used in your curriculum?

  • Look at your own

curriculum.

  • What types of quesFons

are suggested for you to use?

  • What could you add to

the suggesFons?
