All “Zeroes” Addition facts and Subtraction counterparts ## Lesson 2: Ones Facts

Lesson 2 uses the Rule Strategy to teach students how to add “1″ to any number. The Addition facts in this group are very simple for students to master. The instructional videos feature an underwater theme (and island-style music) that keeps students engaged!

Use this Factivation!® Lesson to Teach:

All “Ones” Addition facts and Subtraction counterparts ## Lesson 3: Skip-Twos

Lesson 3 uses the Rule Strategy, with an emphasis on odd and even numbers.  The instructional videos lead students on a mission to build fluency with the focus facts as they travel alongside spaceships carrying Addition cargo. Up-tempo music adds to the excitement and adventure of mastering these facts.

In the Lesson 4 instructional videos, students are taken on a virtual field trip to a garden where they observe snakes, dragonflies, ants, and spiders. Students learn to connect new information to prior knowledge, as all of the creatures they encounter represent the Addition facts  in this lesson. Because of these brain-friendly connections, students have little difficulty remembering the sums.

Use this Factivation!® Lesson to Teach:

1+1, 2+2, 3+3, 4+4, and Subtraction counterparts ## Lesson 5: Little Neighbors

Lesson 5 builds upon the Doubles facts learned in the last lesson. A simple trick makes these facts simple to learn! The instructional videos take students on a trip to the movies as they build fluency down a “haunted” hallway! Cinematic elements make the Lesson 5 videos a hit with students!

Use this Factivation!® Lesson to Teach:

1+2, 2+3, 3+4, 4+5, Addition commutative counterparts (2+1, 3+2, 4+3, 5+4), and Subtraction counterparts ## Lesson 6: Big Doubles

In the Lesson 6 instructional videos, dancing cows make a virtual farm field trip memorable! Students connect the new Lesson 6 focus facts to prior knowledge and are entertained throughout the video lesson, increasing motivation to master the facts from this lesson.

Use this Factivation!® Lesson to Teach:

5+5, 6+6, 7+7, 8+8, and Subtraction counterparts ## Lesson 7: Big Neighbors

Lesson 7 builds upon the Big Doubles facts from Lesson 6. Students are presented with a familiar, previously learned strategy that can be utilized again to master the Big Neighbors facts in this lesson.

Use this Factivation!® Lesson to Teach:

5+6, 6+7, 7+8, 8+9, Addition commutative counterparts (6+5, 7+6, 8+7, 9+8), and Subtraction counterparts ## Lesson 8: Double in the Middle

The last “Doubles” lesson is Lesson 8: Double in the Middle.  The little-known strategy in this lesson allows students to put their Doubles facts to use again, increasing both confidence and fluency. The instructional videos feature scenes of summer fun, including marching picnic ants absconding with the focus facts.

Use this Factivation!® Lesson to Teach:

3+5, 5+7, 6+8, Addition commutative counterparts (4+2, 5+3, 7+5, 8+6), and Subtraction counterparts.

*NOTE: The Double in the Middle strategy can be used for other facts as well: 1+3 and 3+1, 4+6 and 6+4, 7+9 and 9+7.  However; these facts are addressed using alternate strategies in other lessons.  Although 2+4 and 4+2 were previously covered in Lesson 3, we have included them in Lesson 8 to demonstrate to students that there is often more than one strategy from which to choose. ## Lesson 9: Little Nines

Lesson 9 uses the Trick Strategy and a sports-theme to teach students a simple way to remember the sums of all facts with “9″ as an addend.

Use this Factivation!® Lesson to Teach:

9+2, 9+3, 9+4, 9+5, Addition commutative counterparts (2+9, 3+9, 4+9, 5+9), and Subtraction counterparts.

*NOTE: Although 9+2 and 2+9 were previously covered in Lesson 3, we have included them in Lesson 9 to demonstrate to students that there is often more than one strategy from which to choose. ## Lesson 10: Big Nines

Lesson 10 builds upon the last lesson, utilizing the same strategy to conquer all “Big Nines” facts.  The instructional videos’ fairy-tale theme, cinematic music, and familiar characters keep students enchanted and engaged in their learning.

Use this Factivation!® Lesson to Teach:

9+6, 9+7, 9+8, 9+9, Addition commutative counterparts (6+9, 7+9, 8+9, 9+9), and Subtraction counterparts.

*NOTE: Although 9+8 and 8+9 were previously covered in Lesson 7, we have included them in Lesson 10 to demonstrate to students that there is often more than one strategy from which to choose. ## Lesson 11: Tele-Tens

Lesson 11 uses a familiar cell phone keypad to teach students all facts with a sum of 10!  Isn’t technology wonderful?

Use this Factivation!® Lesson to Teach:

1+9, 2+8, 3+7, 4+6, Addition commutative counterparts (9+1, 8+2, 7+3, 6+4), and Subtraction counterparts.

*NOTE:  Although 1+9 & 9+1 and 2+8 & 8+2 were previously covered in Lessons 2 and 3, we have included them in Lesson 11 to demonstrate to students that there is often more than one strategy from which to choose. ## Lesson 12: Final Facts

The groovin’ animals in the Lesson 12 instructional videos will tickle your students’ funny bones as they are practicing the Final Facts!  The last five Addition facts are presented using the Chant Strategy.  At the completion of this lesson, all Addition facts have been mastered.
