2nd Grade Math Facts: Addition and Subtraction
I thought my son was pretty good at his addition and subtraction math facts. We had used math fact triangles as part of his math homework, and he plays math apps (when forced between no screen time and math app screen time). We worked on math all summer with Rising 2nd Grade Daily Math Problems assigned by his school.
His teacher was excited to introduce a free program called XtraMath. It tracks what problems your child gets correct and serves up the facts you need to work on. You need to get the facts correct within 3 seconds per problem to pass. It turns out that he had more to learn in order to get his math facts 100% correct within 3 seconds per problem. We never limited the time before and that made a huge difference.
At first, my son was fine with XtraMath but he’s better at addition than subtraction. After 6 days of subtraction, he still had about half his math facts to go. I thought that pretty good but then the XtraMath sessions got tortuous with him. He simply found it painful. He refused to focus. Used his toes or a toy to hit the key. Held the key down too long so the next problem was wrong.
The issue is it’s basically online flashcards. Nothing fun about that. I wish there were modules to give the fact problems in a gaming style. Or, math games tracked what problems are incorrect and correct and served up problems accordingly. XtraMath, the race the teacher mode, has a nice feature that repeats any problem that is incorrect thus helping to reinforce that math fact.
The green boxes show the facts my son knows. Yellow are facts he usually gets correct (within 3 seconds) and grey are the facts he needs to master. We see this chart with the fact each time we log in.
Today, we switched to a free web subtraction shooting game called Minus Mission. My son needed a change of pace. Here are more great games on free websites to try if you need to change it up:
- Minus Mission Shooting (you know the answer and have to shoot down the problem)
- Island Chase Subtraction (subtraction racing game against other kids)
- Sailboat Subtraction (tug of war against another team using subtraction facts and the “muscle”)
- Alien Munch (you can choose the fact families 1-12)
- Flying High (design your own plane to fly through the correct answer. Choose the fact family you want to work on.)
How about you? What are you using to learn 2nd grade math facts for addition and subtraction? Thank you for sharing!
