LEGO BEIS HAMIKDASH PROJECT
​
Rabbi Worch and Reb Reuven along with the young boys at Cheder Lubavitch completed the building of the Third Beis Hamikdash…out of LEGO. With incredible detail such as windows and awnings-all to scale (a lego block per cubit)- the boys learned the Laws of the Beis Hamikdash while having fun in the process. The Lego edifice will be housed in the library at the school. Rabbi Worch explained to the boys that each time we do a mitzvah we have to see it as another block added to the House of Hashem. If we all work together we can merit the full size version speedily in our days.​

THE TORAH MATH PROJECT
​​​
The Torah Math Project website is meant to be a collaborative effort to teach Torah while bolstering students’ math skills. The goal is to have thousands of new Torah MATH problems so we need your help! Submit a Torah question that requires math to answer. Make sure to include the solution and steps you took to get there.
Click here to go to the website! Here is a sample Torah math problem:
​
In Parshas Emor (Vayikra 23:42) we are commanded to sit in a succah on Succos. A sukkah cannot be more than 20 amahs high and it cannot be lower than 10 tefachim. The opinion of R Avraham Chaim Na’eh is that an amah is 18.9 inches. According to the opinion of the Chazon Ish an amah is 22.7 inches (Frank, The Practical Talmud Dictionary) there are six tefachim to an amah.
​
What is the tallest possible sukkah to the nearest foot without going over 20 amahs? Give the answer according to the Chason Ish and of R Avraham Chaim Na’eh .
According to of R Avraham Chaim Na’eh
20 amahs x 18.9 inches = 378 inches = 31.5 feet
​
Since rounding to 32 feet would be above 20 amahs according to R Avraham Chaim Na’eh we would have to round down to 31 feet.
According to the Chazon Ish
20 amahs x 22.7 inches = 454 inches = 37.8 feet
​
Since rounding to 38 feet would be above 20 amahs according to Chazon Ish we would have to round down to 37 feet.
What is the shortest possible sukkah in feet to the nearest foot without going under 10 tefachim? Give the answer according to the Chason Ish and of R Avraham Chaim Na’eh
According to of R Avraham Chaim Na’eh 10 tefach = 1.67 amah
1.67 amahs x 18.9 inches = 31.56 inches = 2.63 feet
We would round up to 3 feet.
According to the Chazon Ish
10 tefach = 1.67 amah
1.67 amahs x 22.7 inches = 37.9 inches = 3.15 feet
​
Since rounding to 3 feet would be below 10 tefachim according to the Chazon Ish we would have to round up to 4 feet.
