As part of our morning procedures, my students solve the problem and drop it in the bucket.
I had a parent question why I was using ONE question to determine if they needed additional homework on that particular skill. After all, no one is perfect. My justification is that there may only be ONE problem on high stakes testing that determines if they know how to complete this skill. I need them to be able to demonstrate in only ONE problem, what they can do! It also encourages students to slow down and double check answers. I often remind them that it makes more sense to take your time on that one problem than to rush through and receive additional homework.
In many cases, my students answers are very close to the correct answer. For example, when we multiplied decimals, I had many students who had all of the correct numbers, but their decimal was in the incorrect place. On Indiana's standardized test, our questions are no longer all multiple choice. Many of our answers require the students to type in their answer. Meaning, it is 100% up to the students to compute and key in the correct answer. I really feel that this has helped the computation portion of this.
