  • 2017 Summer Mailing Forms - Update 8/10/17

    Please see the Connect-Ed message that was sent to families on the morning of July 18 regarding the new process for the 2017 Summer Mailing Forms. Please select "Read More" for updates.

    SUBMISSION OF PHYSICAL: You may now upload an electronic copy of a doctor-completed physical form within the Physicians section of the Summer Mailing Forms. If you have already completed your other forms and would now like to upload a physical, please log in to view your summary and select Edit from the drop-down. You may also send it in hard copy to the child's school, or email it to the school's klschools address located in the Contact Information. You do not need to provide it here if it has already been submitted in a 2017-18 Fall Athletics registration.

    STUDENT NAME NOT APPEARING: your student's name will be pre-populated as a participant choice only if he/she has previously participated in HS or MS athletics.

    SECTION SELECTION (the first data-entry field): please select the SECTION that corresponds to the grade level that this PARTICIPANT will be entering in the Fall. If the school and grade level that you need do not appear, then you may have selected the incorrect program for this PARTICIPANT. Please return to the dashboard and enter the full name of the school into the "I want to register for a program at" field.

    FINDING ANOTHER PROGRAM: if you have finished with your John Jay High School 2017 Summer Mailing Forms submission, and would like to next submit your HS athlete's forms for the Athletics Dept, please  return to the dashboard and enter  John Jay Athletics into the "I want to register for a program at:" field.

    UPLOADING A HEALTH APPRAISAL FORM: if you have completed your child’s summer mailing forms, and would like to go back in to upload his/her Health Appraisal Form (required for grades K, 2, 4, 7, 10 and all new entrants), please use the “View or Edit my Registrations” button to update the existing Participant record for your child.

Hands-on learning opportunities provide exploration and practice.

 Mr. Egeler's classroom is festive with one-of-a-kind cellophane kites. They hang in rows from the ceiling and wave as students walk below..

 "Seventh graders designed kites as  part of unit on quadrilaterals," said Mr. Egeler. "They were free to do what they wanted as long as the shapes were symmetrical." The resulting squares, rhombuses, trapezoids, pairs of acute triangles, and kites were painted, and demos scheduled on John Jay's Contest Field.

"The secret is in the surface area," said Mr. Egeler, "That, and the angle that the bridle is attached."  

The seventh grade kite project bridges the Big Ideas Math unit on quadrilaterals and the following one on calculating  the surface area of various geometric shapes. 

Step Inside Seventh Period Surface Lab

  Mr. Egeler met his seventh period, seventh grade math class at the door, handing each student a number as they entered the classroom.

“We're doing a surface area lab,” he said. “This is your seat assignment today.”

The desks had been moved into seven groups of four. On top of each grouping of desks, a box with a number on it held four calculators and two shapes.

The students found their tables and began taking the shapes out of the box. Some found a Morton Salt cylinder and a triangular Toblerone chocolates prism, others found a Rubik cube or pyramid, and a clear plastic rectangular prism. All were familiar friends, as the class had just finished a unit on calculating the surface area of these shapes.

“All you need on your desk is a pencil. I will give each group a lab data sheet,” said Mr. Egeler. “You will be working as a group, and graded as a group.”

A stopwatch on the whiteboard showed four minutes.

“You will have four minutes to pick a shape from the box, measure it, and calculate its surface area,” he said. “I will walk around and help you if you need it.”

Mr. Egeler gave the students four rules.

  1. Write your group’s answers on your lab data sheet.
  2. After four minutes are up, you will change tables. Table one will move to table two, and so on. Take your data sheet with you.
  3. You cannot repeat shapes as you rotate through the tables.
  4. Take your measurements in centimeters, and provide your answers in square centimeters.

As soon as Mr. Egeler said, “Begin,” the room began to buzz with math talk.

“I'll measure its circles and sides,” said a student in the group that picked out the Morton’s Salt container.

 “Use the formula,” said another. “Do you remember it?” Their hands shot up.

Mr. Egeler arrived. “The surface area of a cylinder is 2 × pi × r2   +  pi × d × h.

“What do we do with this?” asked a student in another group, holding the Toblerone box.”

“The surface area is made of five shapes. Two triangles at each and, and three rectangles around the sides,” a group member reminded him.

“I know the formula?” said another, scribbling it down. The students knew there are multiple approaches to solve problems.

Around the room, seventh graders practiced collaborative discovery, helping each other measure, analyze and calculate.  

Seven rounds of four minutes, plus instruction, fit neatly into the 40-minute period.

Big Ideas Math Is Used in JJMS' Seventh and Eighth Grade


  Last year, the district set up a comprehensive study of various math programs with the intention of adopting one for implementation in seventh and eighth grades.

The Middle School Math Committee selected Big Ideas Math because of its robust features that support all levels of students, from Skills Review and Basic Skills Handbook for students who are struggling to the Enrichment and Extension worksheets for advanced students. The program also has additional online materials which provides immediate feedback,  extra practice problems, online homework checks, and live tutorials for some homework problems.

Big Ideas Math is published by Big Ideas Learning. It is created by Dr. Ron Larson, a professor at Penn State whose textbooks are known for their readability, accuracy, and real-life applications, and Dr. Laurie Boswell, an experienced math teacher. Big Ideas Math grew out of the National Council of Teachers of Mathematics’ Focal Points for K8 and the Common Core State Standards.
