While I am generally not a proponent of memorizing math facts, there are some facts that are important and helpful to know because they aid students in problem solving strategies and form a solid foundation for later learning.

When working on addition, knowing and easily recalling the doubles addition facts helps with number sense and fluency, and can then be used to solve harder problems.

• Ladybug matching game (doubles from 1-9)
• "Doubles +1" strategy page and practice

The first pages in this download are cute ladybug matching cards, because practicing by playing games is so much more fun!

• To set it up, simply print the cards on card stock or scrapbook paper so they are not see through and then laminate for durability.
• Then cut out the cards and you're ready to play!

To play, simply lay the cards out in rows, face down.

Players then take turns flipping two cards. If they find a match between a ladybug and a math equation, they must solve the problem.

(For example, they must match the "2 + 2 =" card to the ladybug showing 2 spots plus 2 spots. They would then say, "2 + 2 = 4.")

If they do not solve the problem correctly, they must replace the cards.

Players take turns looking for matches and solving the problems until no cards remain.

The player with the most matches wins!

Students use the picture of the ladybug to write an addition sentence and then solve the problem.

And finally, after practicing addition and mastering the doubles addition facts, you can introduce your kids to the "doubles + 1" addition strategy.

The point of this strategy is to use known facts (such as 7+7) to solve unknown problems (such as 7+8).

In other words, if your child knows that 7 + 7 = 14, then they can solve 7 + 8 as 7 + 7 + 1. This would be 14 + 1 = 15. (Hence the name, "Doubles + 1.").

The key to this is helping kids see when to use this strategy. The fact page gives one example, but take some time looking at lots of different examples and ask your child how they can use what they know to figure out what they don't know.

And try to let them think through and explain it in their own words rather than trying to get them to repeat things back word for word (because that's just more memorizing).

For example, give them the problem 6 + 5.

Now, since we have called this the "doubles + 1 " strategy, you can solve it using "5 + 5 = 10" and then add 1.

But your child might see that it is also just as true to add 6 + 6 and then subtract 1.

And that's great! There's always more than one way to solve a math problem, so encourage thinking, discussing and problem solving!

I hope you find this ladybug math pack to be not only a fun way to practice but also a tool to help your child with addition strategies!
