Almost 900 children from 27 schools across the UK - and one from Israel - have tested their Jewish knowledge at the Etgar challenge at Wembley Stadium.
In its fifth year, the annual cross-communal event sees Year 5 pupils answer questions on Judaism and Jewish history.
Pupils' creative talents were also on show, with teams writing a rap, designing a poster and creating a newspaper front page.
One of the teams from Beit Shvidler Primary School, in Edgware, scored 96 out of 100 to win the quiz, narrowly beating Kerem School and North West London Jewish Day School.
"BSPS are really delighted to have won Etgar, " said Eliezer Segal, Director of Jewish Life and Learning and Assistant Head of the school. "It's a real testament to the children's and teachers' efforts."
Kerem was also named best overall school, while Sacks Morasha won the best front page, judged by JC editor Stephen Pollard, and North Cheshire Jewish Primary School created the winning poster.
Jo Rosenfelder, Etgar co-founder and director, said: "It's great to have so many schools take part. It was our biggest event yet. The northern schools in particular always talk about how much they look forward to it and you can see the children engaging."
Rabbi Jeremy Lawrence, the senior rabbi at Kinloss Synagogue and honorary principal of Sacks Morasha School, said it was an "absolutely outstanding" event.
He said: "It's great to see such huge enthusiasm. The kids are really psyched up for study. It's amazing."
The quiz was interspersed with live music, led by Rabbi Marc Levene, and Chief Rabbi Ephraim Mirvis and Rabbi Joseph Dweck also spoke.
Danny Bootle, a pupil at Brodetsky Primary School, in Leeds, said it was an "amazing day".
He said: "There aren't that many other Jewish people in Leeds, and it's really fun to be here. It makes you feel less alone. It's really fun seeing so many other Jewish kids."
