Your Kids Aren’t Learning Their Addition Facts? Try This…Part 4
So far if you have followed my previous posts, students will have learned their bonds of 10, their +1, +2, +9, +10, and adding one more to their bonds of 10 facts. Next, I like to focus my students’ attention on learning their doubles. Most of the time students are already comfortable with their doubles up to 5+5 since they easily see these doubles on their fingers, on dice, and in other real world examples. At least when working with my intervention groups, this is the case. The doubles kids most often struggle with are 7+7, 8+8, and 9+9. When writing the doubles on the board, kids can easily see that the sums of double numbers turn out to be even numbers or the numbers that count by 2’s.
I also like to use videos and games to help kids remember their doubles. Here is one of the videos that I like to use.
This is only a preview of the video. The other part used to be free but is no longer free. The video costs $2.49 to download the 6-10 doubles, but is worth the purchase in my opinion.
After kids have learned their doubles, show them these doubles plus one more. Don’t tell them that they are doubles plus one more, but let them see the pattern and tell you about them.
Allow the kids to notice the pattern in the doubles and doubles plus one and express to you how the numbers change when one is added. Kids will excitedly see the relationship between the double and how it goes up by one more. After discussing the patterns from the previous posts, students will more readily see this pattern and relationship. Then when using flashcards to follow up, students will sometimes think out loud about their strategy, and you will hear them thinking about the relationships they see to get to a new sum. When you hear this you know you have taught them well!
