## Effective Questioning in the Mathematics Classroom

Effective questioning in the mathematics classroom aims to support critical thinking about mathematics and helps students explain their understanding for themselves and others. Such thinking is a necessary part of the development of numeracy. Numeracy helps students to develop their ability to use what they have learned and increase their retention of the ideas of mathematics.

MCC8.G.3: Describe the effect of dilations, translations, rotations and reflections on two-dimensional figures using coordinates.

The coordinates of three corners of a house roof are (1,4), (5,4) and (3, 9). If the entire house is moved by reflecting in over the y-axis, then translated 2 units up and 1 unit left, what are the new coordinates of the house roof?

Our Math Team students cordially invite you to participate in their first annual Martin Luther King Middle “Making Math Meaningful” Tournament to be held this year on Thursday, December 11th, 2014 at Martin Luther King Middle. We hope that your school will be able to join in this event.

At this Math Tournament there will be one level of competition: Middle School (6th, 7th, and 8th Grade). You may bring up to a maximum of 9 middle school students to participate (3 students for each grade level).

The schedule for this competition is as follows:

5:00 - 5:30 PM Registration

5:35 - 6:35 Individual Written Test: The individual written test contains 20 multiple-choice questions and 5 free-response questions with a 60-minute time limit. A student can expect questions from the following area of mathematics: The Number System (6th, 7th and 8th Grade), Expressions and Equations (6th, 7th and 8th Grade), Functions (7th and 8th Grade), Geometry (6th, 7th and 8th Grade), Statistics and Probability (6th, 7th and 8th Grade), Ratios and Proportional Relationships (6th Grade). The scoring for the written test is 5C+B, where C is the number correct and B is the number left blank. Incorrect answers earn zero points. NO calculators may be used on any part of this written test.

6:40 - 7:25 Team Ciphering: The team ciphering consists of 5 problems, given one-at-a-time, each with a two-minute time limit. Students earn 11 points for answering correctly within the first minutes, and 5 points for the second minute. Calculators will NOT be allowed for the individual ciphering questions. . (Only one set of answers can be submitted from each three member team.)

This course will engage teachers as mathematical thinkers by having them solve problems to deepen their understanding of mathematics.

The objective of this course is to build teachers’ mathematical knowledge and capacity in order to use it to increase student achievement.

The session will take place in the South Atlanta School of Health and Medical Science Media Center.
