This is really long, but I hope it is some help to you.
My daughter is 7. We work with only a few new facts at a time. We started with all the facts that add up to 3, then 4, then 5, etc. She learns subtraction at the same time. I do not move her along until she is able to answer an oral drill quickly. I quiz her out loud on both addition and subtraction and I make sure I do not ask her facts in order. I want to make sure she has mastered them. I will also quiz the problem facts over and over to help her learn them.
We start new facts with manipulatives and gradually move to worksheets and oral drill. Our manipulatives are sometimes goldfish or m&ms to spice things up a bit.
I have a chart posted with all the addition and subtraction facts I want her to learn. Whenever she can consistently and quickly answer my oral drills we put a star on the chart near that fact and celebrate.:hurray:
My chart is divided into 4 sections. When she reaches the end of a section she gets a reward which is usually a trip to Borders with mom.
Every morning I have her doing online drill from the Saxon or Math-u See websites. She likes these because they are like a game to her. You can set the drill to target specific problems so that your child is working on mostly the facts you have been teaching. It takes her all of 5 minutes, but it provides a good reinforcement while I am getting things ready for the day.
Before her daily math lesson she uses Mathshark, which is something like Flashmaster. She is currently working on adding and subtracting 2 and 3. I set the drill so that she is asked the facts out of order.
Our daily lesson consists of worksheets from a website that is no longer online mixed with worksheets I have made myself that are tailored to her weaknesses. Previously mastered facts are also included in worksheets periodically. There are many online sites where you can print worksheets. I prefer to make my own because I can specifically target weak areas based on the oral drill I've done. I also spice them up with pictures that interest her. Horses work really well! I sometimes have her do some timed tests on facts she has just about mastered. The tests I use are short and I don't make it a high pressure situation. With my son I would have had to use a different approach to timed tests because he would have freaked out.
For my Math phobic child I would highlight one row (about 5 facts) of problems and ask how long he thought it would take him to finish them. He would say something ridiculous like "a half hour". Then I would challenge him to complete them. Of course he would finish in minutes. This served the purpose of giving him a realistic idea of how quickly he could finish the page.
My daughter is also working her way through Two Plus Two is Not Five: Easy Methods to Learn Addition and Subtraction, by Susan Greenwald. This is a reproducible book. I have grown tired of making copies, but recently discovered that my local copy store will copy up to 30 percent of the book at a time. I may end up having the rest of the units copied for me. I wish I had used this with my son. It seems to help them remember without making them completely rely on tricks.
Every 2-3 days I quiz her orally to see how well she knows new facts and also to see if she is retaining previously mastered facts. This is when she can earn stars for the chart, or possibly move into a new section. I often make notes on the chart so I know which ones she had trouble with. That is how I know which facts to include in my worksheets.
Every now and then for variety I mix in a lesson about time, money or measurement or some other chapter from our Bob Jones 2nd grade Math. But addition and subtraction drill is the core of her math for this year. We will continue making our way through the BJU Math 2 lessons after I see that she has mastered her facts. My son was rushed through this stage of learning and operated with a "fact handicap" for years which really frustrated and slowed him down as he tried learning more advanced math.
Her actual lessons do not take long, but the copying and prep are time consuming. I've tried many drill programs and have found that this method works best for us. I think it will pay off in later years.
Forgive me for going on and on. If you are interested in seeing some of the worksheets I designed feel free to e mail me.
