Lesson: 

 


         

Introduction:  The teacher will explain the importance of knowing the correct time of when Jews can’t eat anymore chometz on the eve of Pesach.  The teacher will work through an example using hypothetical times.  Students will work along with the teacher, using their calculators.  This will help the students understand the process and will be able to do it themselves.

 

Lesson:  The teacher has to supply the students with two times, sunrise and sunset.  To find out the crack of dawn you have minus 72 minutes from sunrise.  For example sunrise this year on the day before Pesach is 6:41am seventy-two minutes before that is 5:29am.  Then to find the time the stars come out, you take the sunset time, which this year is 8:11pm and adds seventy-two minutes, which would be 9:23pm.  A whole day is considered from 5:29am till 9:23pm.  Then the student will have to divide the day into 12 equal parts.  The child will find out that the day is divided into 12 parts of one hour and nineteen and half minutes each, for our example.  It is brought down from our sages that we can only eat chometz till one third of the day.  In our example that would be until 10:47am.  Our sages also teach us that a person can only get benefit from the chometz up until one fourth of the day.  In our example that would be until 12:06pm. 

          The teacher will provide only two times sunrise and sunset and the students will have to figure out using the calculations what time can they last eat chometz and the last time to get enjoyment from the chometz.

 

          Closing Activity:  The students will be expected to calculate the times of when they can’t eat chometz if Pesach would come out a week later.  They would have to figure out the times using May 1st as hypothetical beginning of Pesach.  Students will look in the newspaper for the sunrise and sunset times.  Using that information they will calculate the times and bring the answer to class.
