Here are the steps that will help students become proficient!

Here is a FREE game to learn the combinations or pairs of 10. This is a great game to help memorize the pairs. Just click the picture on the left to download this free game.

Next, teach adding a 10 to a number. For example; 3+10. This should be done with no thinking. Counting by 10's from any number is essential! They should NOT be counting 10 more on their fingers. This needs to be automatic. They should be able to count by 10's going forward and backwards from any number. Students should also be proficient at counting 1 more and 1 less from any number. Here is a FREE resource to help with adding and subtracting by 1's and 10's.

Then, teach adding a 9 to a number. For example: 3+9. If they know how to add 10, they just subtract 1 less. This will help exercise the brain moving forward and backwards on a number line. Most students need help seeing the 9 in the equation. Sometimes they sit and stare at the addition fact with a blank stare until I say, "I see a 9." Then right away they know what to do. It's training the brain to see the 9 and connecting it with a trick they know. If you know how to add 10, then you can add 9 with ease. This is helpful when subtracting too. Students really need to be proficient in counting forward and backwards on a number line with simple arithmetic like 1 more or 1 less.

Once these steps are masters, students will be thinking in their heads combinations of numbers, looking for pairs that make 10 or a double, and begin using a strategy other than their fingers.

When they get to a fact like 4+7, they may think, "I know that 3+7 is 10, therefore 4+7 must be 11." or they may think, "I know that 4+4 is 8, therefore 3 more make 11." Or they may think, "I know that 4+6=10, then 1 more would make 11." These 3 examples use strategies other than fingers.

The best way to learn these strategies is to practice, practice, and practice. We can't be good at something if we don't practice. Right?

Teaching to take numbers apart like using Number Bonds and connecting them with what you know is very helpful. I found a YouTube video that explains Number Bonds pretty well. Click here to watch a video about Number Bonds.

Here are some fun resources that will help master addition facts and to practice the strategies listed above.

Is this a good place to start for kindergarteners?? Or should this be more geared towards first graders?

ReplyDeleteI think the earlier the better. Start simple with facts of 10.
