How much time do you give your students to complete timed addition facts drills? How many problems do you give them at a time? How many problems do you expect them to solve correctly in that time? How about for subtraction facts?

I use Saxon math which incorporates daily fact practice. Right now we've covered doubles [4+4], adding 1, adding -, subtracting the same number [6-6], subtracting 1 and subtracting 0. They do a 20 problem, mixed fact sheet each day, and most are able to finish within 3-4 minutes with very few mistakes. We also do flashcards [either whole class or individually] daily, so we get lots of practice.

Timed Math Facts

In the district I teach in timed math facts (subtraction and addition) are a part of the students report cards. For the first trimester the students were expected to complete 36 problems in 6 minutes. This time was for both sub and add. My students did really well. For the second and third trimesters the students will need to complete 42 problems in 7 minutes. We practice at least three times a week so the students will not feel so overwhelmed when it comes to repot card time

timed tests

In my district students are expected to pass 40 problems in two minutes. They must get all of them correct to move to the next level. Addition and subtraction are not mixed together. We work on both addition and subtraction in math, but for timed tests, students must pass all the addition tests before moving to subtraction. We also put a timed test grade on the report card.

timed tests

I use great books called one minute math and they cover addition 0-10 in one book - move onto addition 11-20 and the same for subtraction. I also call the timed tests "Beat the Clock" and the kids love it. The word "test" is not mentioned. I give 2 minutes and allow 2 errors. There are 30 problems on the page. It also gives a fun recordiing sheet that I send home - I NEVER post standings in the classroom. I am finding these very successful - it's my first year using them.

What is the name and publisher of the book? It sounds like something that would help my students. Thanks.
