Making Addition and Subtraction Facts Stick

I've been wracking my brain for years, trying to think of a way to get those basic facts to stick! There is way too much math that depends on knowing the basic facts, so we want the little ones to go beyond the "counting on fingers" or "counting on in your head" stage!

We've been using this sequence for learning facts at my school, and I must say, the kids are getting it! We all know it's not a good idea to introduce all the facts at once. There are 200 facts to be learned, and learning them in some systematic way is necessary. My knowledge of brain based learning tells me we need to help the children make connections, use visuals like color and pictures, practice frequently, add a social component, and make it fun. This will all help those facts stick!

I've taken 8 basic patterns and made 8 color coded sets of cards to be practiced based on these concepts:  plus one families, plus 10 families, plus 9 families, sums of 10, doubles, doubles plus 1, plus 2 families, and the remaining facts.  The "families" include 2 addition and 2 subtraction facts for each fact.  (For example, 1+8=9, 8+1=9, 9-1=8, and 9-8=1 are all connected.) These connections help children remember! I've even included a game that's connected to the cute little pictures on each card.

Practicing the facts is only half the challenge.  The other challenge is showing mastery.  

I've included assessments with each set.  There are 2 basic assessments with each family. The 2 assessments are both similar. I just thought you'd like a second option so they aren't taking the exact same assessment each time. Each assessment has 5 columns of 10 facts.  I give the children one minute to complete as many facts as they can. (The timing helps distinguish between the kids who know the facts, and the kids who still need to figure them out.) I have found that kids that get 20 - 25 facts in a minute are definitely ready to move on to the next level. (This, of course, is up to you.) Some kids really need a one on one assessment with the cards, as their writing skills just can't keep up with their thinking skills.

  4. The last thing you want is for your room addition to have to be modified or even torn down if you have problems with it that could have been addressed during the planning stage. If you intend to sell your home in the future, it would also be very wise to have a home appraiser take a look at your home as it is now. construction san francisco ca
