How long do you give your students for the 25 multiplication problems?

Hi Julia and thanks for your question. We have found that research supports 4 seconds per problem, so in our district we give students a minute and 40 seconds. (1 minute and 30 seconds in some classrooms.) We know that other districts opt for less time. Our sons are given 1 minute for 25 problems in the district we currently live in. Our suggestion would be to start with 4 seconds per problem to show mastery, but then push some students who may enjoy the challenge to complete the 25 problems in one minute.
